201023662 六、發明說明： 【發明所屬之技術領域】 本發明通常係有關於無接觸之通訊裝置，而更具體而 吕之，是指小型無線射頻識別（RFID)+。 【先前技術】 RFID「標籤」（tags)可被分成兩個寬廣的範疇：主動標 ❹ 籤《 及被動標籤。主動標籤之特徵為一區域電力來源， 像是電池。主動標籤通常藉由在尺1?載波頻率之選擇上進 行廣播之方式來傳輸資訊，其中RF載波頻率之選擇係使 用用一區域產生之RF載波。主動標籤一般是用來在長距 離上傳輸’通常被稱為「遠場通訊」（far fieid communications，FFC)。採用主動RFID標藏之天線有做 的較大的傾向，以允許在長距離上之通訊。 被動標籤則未被供電。被動標籤能從一訊問 (lnterrogating)RF場中取得供給該標籤所需之能源，並藉 由調變該阻抗（其為天線呈現給該訊問場之阻抗）之方式 使用那能源來傳輸回應碼，借此調變該反射回到讀取天 線之訊號。被動標籤一般用來在短距離上傳輸，通常被 稱為「近场通訊」（near field c〇niniunications，NFC)。例 如’運作在13.56MHz的被動標籤一般被設計成能在距 若干公分遠的距離與rFID讀取器通訊。 被動元件一般係連接到「迴路天線」（loop antennas) 〇 201023662 迴路天線之範例係如於2〇〇3年5月27曰授與匸虹以打以 及其他人之美國專利號：6 568 6〇〇中所示。在美國6 568 6〇〇 號專利中所描述之裝置可被認為是「信用卡尺寸」的被動式 RFID卡（更具體而言’一種能符合ISO 7816尺寸需求的卡）。 該迴路天線有必要是大的，因為被動標籤係使用由該天線所接 收的能源來供電，該能源係來自由RFID讀取器處所傳輸之訊 號。 ^ 第12圖顯示隨著時間所發展之電力供應電壓，其係藉由在一 訊問RF場之存在下而整流在迴路天線中所感應之電壓。一旦該 電力供應電壓達到一臨界值’則該標籤作業可不符合回應時間 之規格。低於此一天線尺寸，該電力供應電壓會永遠無法達到 該臨界值’而該標籤則永遠無法啟動。 針對RFID應用之天線设計係在Microchip Technology，Inc之 Youbok Lee博士在2003年所發表（月份未記載）之應用筆記中所 敘述，標題為 “Antenna Circuit Design for RFID Applications”。Lee 博 φ 士的應用筆記詳細描述了如何針對一運作在13.56MHz之被動 式RFID標籤天線來決定其尺寸需求。在該應用筆記之第5頁， Lee博士展示了迴路天線線圈（c〇il)之最佳半徑是等於所需讀取 距離的1.414倍。此分析確認了對於大約若干公分之讀取距離 而言，一信用卡尺寸的迴圈天線可幾乎達到最佳化。 在許多應用中’可看到被動標籤正被廣泛使用著。例如，行 動裝置製造商將被動式RFID標籤嵌入到用於NFC應用之行動 裝置中。示範性行動應用包括，但不限於，票卷販賣以及行動 式付款。於2008年2月19日授與Leizerovich及其他人的美 201023662 國專利號：7,333,062顯示一用於NFC裝置之具有整合式迴圈天 線之行動電話。如美國專利7,333,062號所示，行動電話提供了 實作一 13·56ΜΗζ之迴路天線所必要的真實狀況(real estate) » 在較小的行動裝置中實作被動標籤之方式已嘗試過多次。這 些嘗試未能達成有限的成功，部分是由於該迴路天線尺寸之 故。例如，第13圖顯示一在一安全數位（SD)記憶卡中之RFID 標藏實作，該安全數位（SD)記憶卡係由Wireless Dynamics, Inc. of Calgaiy，Alberta Canada所製造。卡1300包括一天線，但是因此SD 卡明顯地太大。同樣地舉例而言，美國公開號：2006/0124755Α1 顯示一具有被動標籤之記憶卡，但是該卡必須被插入到一插槽 中以存取在不同裝置上之迴路天線。按此實作方式，行動裝置 之真實狀況是仍依賴迴路天線之實作。因此，可預見的是，天 線的尺寸會被當作為要進一步微塑化被動式RFID標籤的障礙。 對於能不用依賴外部裝置來收納天線之小型足跡 (footprint)RFID標籤的需求是存在著。對於能相容於在行動裝 置上之標準記憶卡插槽的記憶卡相容RFID標籤的需求，亦是 存在著的。 【發明内容】 本發明之一態樣係揭示一種對一記憶卡相容之附加插 槽維持未受干擾之電力的方法，該方法包含週期性地對 該記憶卡相容附加插槽發送記憶卡寫入命令。 本發明之另一態樣係揭示一種修改對一雙介面智慧卡 201023662 控制器之電力傳遞的方法’該方法包含以下步驟：將一 隱藏命令喪入到一記憶卡寫入命令内，該隱藏命令係對 一在一記憶卡相容無線射頻識別（RFID)卡上之雙介面智 慧卡控制器’指定進行電力傳遞之修改；以及將該記憶 卡寫入命令發送到該記憶卡相容RFID卡。 本發明之又一態樣係揭示一種修改對一雙介面智慧卡 控制器之電力傳遞的方法，該方法包含以下步驟：在一 鲁 記憶卡控制器處接收一命令’其中該命令包括一指令， 以用來修改對一雙介面智慧卡控制器之電力傳遞，該雙 介面智慧卡控制器係與該記憶卡控制器共同放置在一記 憶卡上；以及修改對該雙介面智慧卡控制器之電力傳遞。 . 本發明之又另一態樣係揭示一種用指令所編碼而成之 • 電腦可讀取媒體’其中當由一記憶卡控制器存取時該等 指令會造成該記憶卡控制器能執行以下動作：在該記憶 卡控制器處接收一命令’其中該命令包括一指令，以用 Φ 來修改對一雙介面智慧卡控制器之電力傳遞，該雙介面 智慧卡控制器係與該記憶卡控制器共同放置在一記憶卡 上；以及修改對該雙介面智慧卡控制器之電力傳遞。 【實施方式】 在以下詳細敘述中可參考隨附圖式，該等圖式僅作為 說明用途而顯示本發明之各具體實施例。該等具體實施 例係充分描述以讓該領域中熟悉技術人士能實現本發 201023662201023662 VI. Description of the Invention: [Technical Field of the Invention] The present invention generally relates to a contactless communication device, and more specifically to a small radio frequency identification (RFID)+. [Prior Art] RFID "tags" can be divided into two broad categories: active labeling and passive labeling. Active tags are characterized by a source of electrical power, such as a battery. Active tags typically transmit information by broadcasting over the selection of the carrier frequency, where the RF carrier frequency is selected using an RF carrier generated by a region. Active tags are typically used to transmit over long distances, commonly referred to as "far fieid communications" (FFC). Antennas that use active RFID tags have a greater tendency to allow for communication over long distances. Passive tags are not powered. The passive tag can obtain the energy required to supply the tag from an lnterrogating RF field, and use the energy source to transmit the response code by modulating the impedance (which is the impedance that the antenna presents to the challenge field). Thereby the reflection is modulated back to the signal reading the antenna. Passive tags are typically used for transmission over short distances and are often referred to as "near field c〇niniunications" (NFC). For example, passive tags operating at 13.56 MHz are typically designed to communicate with rFID readers at distances of a few centimeters. Passive components are typically connected to "loop antennas" 〇201023662. Examples of loop antennas are as follows: May 27, 2002, awarded to Yuhong to play and others' US patent number: 6 568 6〇 Shown in 〇. The device described in U.S. Patent No. 6,568,600 can be considered a "credit card size" passive RFID card (more specifically, a card that meets ISO 7816 size requirements). The loop antenna is necessarily large because the passive tag is powered by the energy received by the antenna from the signal transmitted by the RFID reader. ^ Figure 12 shows the power supply voltage developed over time, which rectifies the voltage induced in the loop antenna by the presence of an interrogating RF field. Once the power supply voltage reaches a threshold value, the labeling operation may not meet the specifications of the response time. Below this antenna size, the power supply voltage will never reach this threshold' and the tag will never start. The antenna design for RFID applications is described in the application note published by Dr. Youbok Lee of Microchip Technology, Inc. in 2003 (not documented in the month) under the heading "Antenna Circuit Design for RFID Applications." Lee Bo's application note details how to determine the size requirements for a passive RFID tag antenna operating at 13.56 MHz. On page 5 of this application note, Dr. Lee showed that the optimal radius of the loop antenna coil (c〇il) is 1.414 times the required read distance. This analysis confirms that a credit card sized loop antenna can be nearly optimized for a read distance of approximately several centimeters. In many applications, it can be seen that passive tags are being widely used. For example, a mobile device manufacturer embeds a passive RFID tag into a mobile device for NFC applications. Exemplary operational applications include, but are not limited to, ticket sales and mobile payments. The benefit of Leizerovich and others was granted on February 19, 2008. 201023662 Patent No. 7,333,062 shows a mobile phone with an integrated loop antenna for NFC devices. As shown in U.S. Patent No. 7,333,062, the mobile phone provides the real estate necessary to implement a loop antenna of 13.56. » The manner in which passive tags are implemented in smaller mobile devices has been tried many times. These attempts failed to achieve limited success, in part due to the size of the loop antenna. For example, Figure 13 shows an RFID tag implementation in a secure digital (SD) memory card manufactured by Wireless Dynamics, Inc. of Calgaiy, Alberta Canada. Card 1300 includes an antenna, but the SD card is therefore significantly too large. Similarly, for example, US Publication No. 2006/0124755Α1 shows a memory card with a passive tag, but the card must be inserted into a slot to access loop antennas on different devices. According to this implementation, the actual condition of the mobile device is still dependent on the implementation of the loop antenna. Therefore, it is foreseeable that the size of the antenna will be used as an obstacle to further microplasticizing passive RFID tags. There is a need for a small footprint RFID tag that can accommodate an antenna without relying on external devices. There is also a need for a memory card compatible RFID tag that is compatible with the standard memory card slot on the mobile device. SUMMARY OF THE INVENTION One aspect of the present invention discloses a method of maintaining undisturbed power for an additional slot compatible with a memory card, the method comprising periodically transmitting a memory card to the memory card compatible additional slot Write command. Another aspect of the present invention discloses a method of modifying power transfer to a dual-interface smart card 201023662 controller. The method includes the steps of: dropping a hidden command into a memory card write command, the hidden command Modifying the power transfer by a dual interface smart card controller on a memory card compatible radio frequency identification (RFID) card; and transmitting the memory card write command to the memory card compatible RFID card. Yet another aspect of the present invention discloses a method of modifying power transfer to a dual interface smart card controller, the method comprising the steps of: receiving a command at a memory card controller, wherein the command includes an instruction, For modifying power transfer to a dual interface smart card controller, the dual interface smart card controller is co-located with the memory card controller on a memory card; and modifying the power of the dual interface smart card controller transfer. Yet another aspect of the present invention discloses a computer readable medium encoded by instructions which, when accessed by a memory card controller, causes the memory card controller to perform the following Action: receiving a command at the memory card controller, wherein the command includes an instruction to modify power transfer to a dual interface smart card controller with Φ, the dual interface smart card controller and the memory card control The devices are placed together on a memory card; and the power transfer to the dual interface smart card controller is modified.

In addition, it is to be understood that the <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; Therefore, the following detailed description is not to be considered as limiting, and the scope of the invention is defined by the scope of the appended claims . In the drawings, like reference numerals will be used throughout the Figure 1 shows a mobile computing device and a small RFID card compatible with the memory card slot. The mobile computing device 11 is shown in Figure i as a mobile phone, but this is not a limitation of the invention. For example, the mobile computing device 110 can be a personal digital assistant (PDA), a smart phone, a mobile phone, a handheld computer, a desktop computer, or any other device capable of functioning as described herein. The mobile computing device 110 includes a memory card slot 112. The memory card slot 112 is a slot that accepts the RFID card 120. For example, the memory card slot 112 can have a physical dimension that is compatible with the RFID card 120 and can have a communication interface that operates using protocols that are compatible with the RFID card 120. As used herein, the term "memory card slot" can be any add-on slot that accepts a card with memory and can be acted upon by a mobile computing device such as the first circle. access. For example, a memory card slot can be compatible with an industry standard communication protocol, or can be compatible with the widely accepted 201023662 protocol. This communication protocol does not have to be officially incorporated into an industry standard. Compatible with the Multimedia Memory Card (MMC) protocol slot, Memory Stick DUO (Memory Stick DUO) protocol, Secure Digital (SD) protocol, and Smart Media (Sinart Media) protocol. The above list is for illustrative purposes only and is not intended to be exhaustive. In addition to the agreements explicitly set forth above, the memory card 112 may be compatible with many memory card slot agreements without departing from the scope of the present invention. The RFID card 120 includes an electronic contact 122' that is part of a host interface that can communicate with the memory card slot 112. For example, the electronic contacts 122 may provide connectivity to a memory card communication protocol. The RFID card 12 includes RFID functionality and may also include memory that is accessible by the mobile computing device 11A. For example, in some embodiments, rFid card 120 includes a smart card controller and an inductive component that can interact with an nfC reader (e.g., an ISO 14443 suitable interface). In other embodiments, the RFID card 120 does not include the φ memory. The RFID card 120 accessed by the mobile computing device 11 can include functions other than memory and RFID. In various embodiments of the present invention, the RFID functionality in the RFID card is accessed by the mobile computing device 110 using a memory card access command. The memory card access commands have been defined for the memory card. Slot 112. Accordingly, embodiments of the present invention enable the RFn) function to perform functions other than memory access without the need to define new commands. In some embodiments A, new commands for RFID are embedded in the data bits, and the new commands are followed by a memory card read/write command. The RFID card 120 then determines whether the newly entered data bit is 201023662 for the regular read/write function of the RFID function. In other words, functions other than the standard memory card function can be accessed through the "hidden" command in the data stream, which can be exchanged using existing memory card access commands and functions. In accordance with various embodiments of the present invention, both existing memory card functions and RFID functions can be implemented without requiring changes to the manner in which the host-side agreement is established. The combination of mobile computing device 110 and RFID card 120 can be used for any purpose. For example, in some embodiments, the RFID card 120 can interact with a point-for-sale payment device to achieve the effect of a mobile payment. Also as an example 'in some embodiments' the RFID card 120 can be used in a mass-transport environment for the sale of tickets in a wave and pay manner, such as MIFARE. Figure 2 shows a block diagram of a mobile computing device. The mobile computing device Π0 includes an antenna 240, a radio frequency circuit 230, a processor 210, a memory 220, and a memory card slot 丨12. In some embodiments, the action calculation β device U0 is a mobile phone, or a mobile phone function. For example, antenna 240 and RF circuitry 23 can be used to communicate with a cellular telephone network. Moreover, in some embodiments, the mobile computing device no is a wireless local area network (WLAN) or wireless wide area network (WWAN) device. For example, antenna 24A and RF circuitry 23 can be used to communicate with a wireless access point. In some embodiments, the antenna 2 and the wireless circuit 230 are ignored, and the mobile computing device i 110 is unable to utilize the wireless connection. The processor 210 represents a processor capable of communicating with other blocks shown in the mobile computing device 11A 201023662. For example, processor 210 can be a microprocessor, a digital signal processor (DSP), a microcontroller, or the like. Further, the processor 210 can be constructed in accordance with a state machine or other sequence logic. The processor 210 can read instructions from the memory 220 and perform actions in response to the instructions. For example, processor 210 can execute program instructions that affect communication between mobile computing device 110 and devices coupled to memory card slot 112. The memory card slot 112 is referenced in conjunction with Figure 1 and described above. Memory card slot 112 includes circuitry that is compatible with RFID card 120. The mobile computing device 110 can communicate with the RFID card 120 by using a standard set of memory card access commands. For example, the processor 210 can use the memory card write command 'to write to the memory within the RFID card 120 and can use the memory card read command to read data from the memory within the RFID card 120. The mobile computing device 110 can access the RFID function in the RFID card 120 using a "hidden" command embedded in the memory card access. For example, a memory card write command can include a unique data string to The memory card write command recognizes a command that is transferred to a purpose other than memory write. In addition, the sector address supplied to the memory card write command can be set to a specific address value to further identify the memory card write command as a converted command. In addition to specifying the address/data value to identify the memory card access command as a command to be converted for purposes other than memory access, the memory access command may include a data bit to further specify the type and function of the hidden command. . The sample format of the hidden command is entered into a 201023662 step as described below. In some embodiments, a read command is issued immediately after a write command to initiate a stream of data from a non-memory card function to a host side, wherein the data of the write command has a hidden command. The combination of the memory card write command and the memory card read command can be used in this manner to form a hidden read command. In some embodiments, the 'memory card slot 112 is powered off after an inactive period' to conserve power. For example, power can be initiated to memory card slot 112 when processor 21 〇 issues a memory card write or read command, but power can be turned off later to conserve power. When the memory card slot 112 is turned off, any device that is lightly connected to the memory card slot is also powered off. For example, if the RFID card 120 (Fig. 1) is face-to-face connected to the memory card slot, the rfid card 120 is also powered off when the memory card slot 112 is powered off. In various embodiments of the invention, processor 210 executes software resident in memory 220 to maintain power to memory card slot ( 12 (and ❿ to RFID card 120). For example, a periodic hidden command may be sent to the RFID card 12 for the purpose of continuing power supply, while the RFID card 120 is expected to provide the functionality of the RFID. Also as an example, a hidden command may be used to cycle power to a station. The purpose of the smart card controller on the card is transmitted to the RFID card 120. These hidden commands are described in detail below in conjunction with the following figures. Figure 3A shows an RFID card with integrated sensing elements and compatible with a memory card. The RFID card 300 represents a possible embodiment of the RFID card ι2 (Fig. 1). The RFID card 300 includes a host interface 31, a memory 201023662 controller 340, a memory 360, a smart card controller 340, a program recorder, a body 3 32, and a small inductive component 35A. The rfid card can communicate with a memory card slot in the "10 computing device. Further, the RFID ίλλ 〇〇 does not require a memory card slot to achieve extended input/output force energy, for example, and is not limiting. In the specific embodiment of the SD, the card 300 can operate on any SD memory card. A memory card slot in the slot that does not require a secure digital input/output (SDIO).主机 The host interface 310 includes an electronic contact to interact with the memory card slot. For example, the host side interface 31 includes contacts such as contacts 122 (Fig. 1). Also by way of example, in some embodiments the host interface 310 includes concealed electronic contacts. The host interface can also include circuitry such as drivers, receivers, terminals, and the like. In the particular embodiment represented by the third map, the memory card controller 340 uses the memory card access command to communicate with the mobile device. The memory card controller can also communicate with the memory 360. The memory card controller determines whether each command should form a memory operation with the memory 360, whether a hidden command should be converted into a smart card controller 33, or whether it is memorized. The card controller 340 should take action in response to the 9 hidden command. In some embodiments, memory card controller 340 executes instructions in addition to being stored in internal memory or stored in memory 360. In some embodiments, memory card controller 340 includes special purpose hardware that is useful in determining whether a command should be converted. In other embodiments, memory card controller 340 can be - in various aspects It is equivalent to the microcontroller of the controller found in the memory card, except for the program it executes. 12 201023662 Can be any type of volatile or non-volatile

For example, 300 is being inserted into a memory card within a mobile computing device that can transmit a memory card access command to access memory 36. Also as an example, the mobile computing device can send a memory card access command with a hidden command. The memory card controller 340 detects the presence of the hidden command and uses the communication bus 342 to transfer all or part of the memory access command to the smart card controller 330. The communication bus 342 can have any number of wires • (C〇nduCt〇rs) and can take any form. For example, the communication bus 342 can be a serial port, a parallel port, or can include a plurality of data wires, a plurality of bit guide lines, and/or a wire capable of carrying a control signal, such as a clock signal. In some embodiments, the memory card controller 34 takes one or more actions in response to a hidden command. For example, the memory card controller 34 can modify the clock signal in response to a hidden command. The memory card controller 340 can detect hidden commands in a number of ways. For example, in some embodiments, the memory card access command can include a particular address value or a particular data value. The memory card controller 34 detects the packet 13 201023662 A command that includes one or both of a specific address value or a specific data value, and appropriately routes the command. The particular address value and special shell value used for this purpose can be considered here as a hidden command address value and a hidden command data value. In some embodiments, the 'memory card controller 34' can detect the presence of a hidden command based solely on the hidden command address value. In these embodiments, the memory card controller 340 checks for a wide memory in a memory. The address value in the card access command, and if the command matches the hidden command address value, then it is converted (or taken some action). ^ In some embodiments, the memory card controller 340 is based only on The command data value is hidden and the presence of a hidden command is detected. In such embodiments, the memory card controller 340 checks a data value included in the memory card access command and converts the command if it matches the hidden command data value. In still other embodiments, the memory card controller 340 can detect the presence of a φ of the hidden command based on both the hidden command address value and the hidden command data value. In these embodiments, the memory card controller 340 will only switch commands if both the memory card access address and the data match the hidden command address value and the hidden command data value, respectively. Hiding command address values and hiding command data values can be specified in a number of ways. For example, all RFID cards can be released with a fixed value. In these specific embodiments, the same hidden command address and/or data value is included in the memory card access command each time the RFID function is accessed. Also as an example, different RFID cards can be released with unique values. In these specific embodiments, each RFID card can provide these values when needed. Also as an example, the hidden command address and/or data value may be specified by the mobile computing device. In other further examples, the hidden command address and the f-value can be dynamic. The hidden command address and the data value may be changed each time power is applied or on a periodic basis. The smart card controller 330 receives the hidden memory 7 smart card controller 330 converted by the memory card controller 34 to further translate. These hidden commands include hidden commands such as φ and perform actions in response to this. The smart card controller 330 executes the instructions stored in the program memory 332. In some embodiments, the program memory 332 is embedded in the smart card controller 33, while in other embodiments the program memory 332 is part of the memory 36'. The smart card controller 330 is a dual interface smart card controller having one of a plurality of interfaces including the rFID function. In some embodiments, the smart card is a passive rfid tag reader that is compatible with the NFC application. For example, smart card controller 330 can be a device that implements all or part of the ISO 14443 standard for contactless NFC devices. Also as an example, the smart card controller 330 can be a dual interface smart card controller capable of implementing both ISO 7816 and ISO 14443 for contact/contactless requirements. The "SmartMX" family of controllers available from NXP in Netherlands is an example of a suitable dual interface smart card controller. These controllers provide RFID functionality at 13-56 MHz. Various embodiments of the present invention operate at 13.56 MHz, but are not limited to operating at this frequency. In some embodiments, the Smart 15 201023662 card controller interacts with the MIFARE system for ticketing applications. The smart card controller 330 receives power from the host interface. By not receiving power from the interrogating RF field, the necessity of a loop antenna for power generation can be negated. The smart card controller 33 includes an antenna 334 334. The antenna 埠 334 is coupled to the small inductive element 35A. The small inductive element 350 includes a coil wound around a magnetic core. The coil is too small for drawing power from the interrogating RF field, but the power card controller 330 is powered by the host device through the host interface 310, so this method is not necessary. The small inductive component 35 interacts with the antenna within the RFID reader and interacts in a manner similar to the interaction of the primary and secondary coils within the transformer. The RFID reader has a coil that resonates at 13.56 MHz, which functions as a main line of a transformer. The small inductive component 35〇 functions as a secondary line of the transformer. Accordingly, the transmitter can "see" the impedance of the secondary coil (small sensing element 350). The smart card controller 334 can use the circuitry to modulate the reflected signal to modify the impedance at the antenna 埠 334. The small sensing element 350 can be made very small. For example, in some embodiments the RFID card 120 is a miniSD card and the small inductive component 350 is small enough to be completely contained within the apparent size of the miniSD. The specific embodiment of the small inductive element within the apparent size of the delta memory card is as described below with reference to Section 4. In various embodiments of the invention, the memory card controller 34A and the smart card controller 330 are implemented in a number of different manners. For example, in some embodiments, the various components are implemented as hardware. In these 16 201023662 implementations, various (4) can be implemented as individual integrated circuits, or as a combined-composite integrated circuit. Also by way of example, in some specific embodiments, the various components can be implemented as a software, or a combination of hardware and software. In some embodiments, the RFID card can include a - microprocessor ' and the components can be implemented as a software module running on the microprocessor. In other embodiments, rfid+3〇〇 can include multiple processors' and the components can be implemented as software modules interspersed across the plurality of processors. The figure shows a block diagram of a memory card compatible card with integrated sensing elements. The RFID card 302 represents a possible embodiment of the RFID card 12 (Fig. 1). The RFID+3〇2 includes a host interface 31〇, a “• hidden card controller 340, a memory 360, a smart card controller 34”, a program memory 332, and a small sensing element 35〇, all of which are referred to above. 3A is as described. The RFID card 3.1 can communicate with a three-memory card slot in the mobile computer device. Further, the φ card 322 does not require a memory card slot to implement an extended input/output function. For example, and not by way of limitation, in an SD embodiment, the RFID card 3〇2 can operate in any SD memory card slot without the need for a secure digital input/output (SDIO) memory card slot. In the particular embodiment represented by Figure 3B, the smart card controller 33 receives power from the memory card controller 340. In these embodiments, the memory controller 340 can be directly controlled by the power provided by the smart card controller 33A. The memory controller 34 can apply and/or remove power from the smart card 17 201023662 controller 330 in response to commands received through the host interface. For example, the memory controller 34 can receive a hidden command to reset the smart card controller 330 by re-starting through power cycling. Figure 4 shows a photo of a memory card compatible RFID card with integrated sensing components. The RFID card 12 is displayed in an apparent size of an SD card, which is not a limitation of the present invention. The RFID card 12 includes an electronic contact 122, a memory card controller 340, a smart card controller 33A, a memory 36A, a magnetic core 450, and a coil 452, all of which are fixed to the circuit board 4〇2. The magnetic core 450 and the coil 452 can be implemented as a small inductive element 35 (Fig. 3). As can be seen in the photo, the small sensing element can be assembled into the overall size of the memory card. The small inductive component does not provide power to the smart card controller 33, so it is not necessary to make the size larger for this purpose. Figure 5 shows the data portion of a memory card write command. Included are hidden command data values 510, status bar 52 密码, password block 530, device 1D 532, command index 540, and hidden command related information 55 〇. In the example of Fig. 5, the length of the data portion is 512 bytes, which is not a limitation of the present invention. Any number of numbers can be included in the write command, and each of the blocks in Figure 5 can be of any length. In the example of Figure 5, the hidden command data value is 256 bits long, although any length can be used herein without departing from the scope of the invention. In some embodiments, the hidden command data value 51 is used to identify a s replied write command as a hidden command. When a write command receives a data owned by the first 256 bits (which matches the hidden command data value 201023662), the command is recognized as a command to be converted to the smart card controller. As noted above, the hidden command address value can be used to correlate or otherwise be unrelated to a hidden command value to identify the memory write command as a hidden command. When the memory is written as a hidden command, the remaining blocks are more important. For example, if the first 256 bits do not match the hidden command data value (or if the write address does not match the hidden command address value, or ❹ is both), then in the data block The remaining bits are treated as if they were in the general memory write command. Conversely, when the memory write is a hidden command, the remaining fields are used to further translate the hidden command. Memory card controller 340 (Figs. 3 and 4) verifies the hidden command data value 510, status bar 520' and, if possible, the password bar 530 and device ID 532. In some embodiments, if the command is recognized as a hidden command, the memory card controller 340 forwards the password 530, the command index 54 〇 Φ, and the associated material 550 to the smart card controller 330. In other embodiments, memory card controller 340 can take action directly based on hidden commands. Status bar 520 can include any information related to the status of the hidden command. For example, the status bar 520 can include one or more bits to indicate to the memory card controller 340 whether the host side (mobile computing device) desires the smart card to return data in response to the hidden command. For example, when the status rotten 520 indicates a write meaning, the memory card controller 34 will forward the password, device ID, 19 201023662 command index, and related data without expecting to return any data to the host. . Similarly, as an example, when the status bar is not the same, the memory card controller will be in the expectation that the smart card 330 will provide the data in response to a memory card read command to send the material to the host. , forward the cryptographic device 1, command index, and related materials. The combination of the S memory card writer command followed by the memory card read command can be used to provide the "read" function to the smart card to cry Α ^ A ^ tl control tl IS. The reading operation from the smart card controller is further described below with reference to Fig. 8. The password field 530 includes a password to allow the smart card controller 330 to authenticate the token (10) en with the host. In some embodiments, each hidden command includes a milma. Each time the cryptographic device is out, the command index, and the related data are converted to the smart card controller, the password is checked to authenticate the token with the host. - Device 10532 uniquely identifies the host (mobile computing device). The device ID can be checked by the smart card controller to ensure that the token is inserted into the host side of (4) it is being inserted. Some embodiments of the present invention use device m to enhance a unique host/card pair, while other embodiments allow the smart card controller functionality to be accessed by any host. The command index 540 identifies the type of hidden command. The number of possible hidden commands is limited only by the number of bits configured on them. Any number of bits can be configured to the command index 54 without departing from the scope of the present invention. The hidden command related material 550 can be used differently for each type of hidden command. Any number of bit data 550. Used to conceal command related 20 201023662: The data shown in Figure 5 is provided as an example and the data block of the memory card access command may include the field shown in Figure 5 More or less of the data store y, the bar within the card access command::::: The invention is not limited by the memory. A flowchart is shown in accordance with various embodiments of the present invention. In some embodiments, the method 6 can be used by a mobile computing device to communicate with an rfid card within the memory card slot. In some embodiments, the method_, or a portion thereof, is performed by a mobile computing device having a memory card slot, while in other embodiments the 'method_, or portion thereof, is The software is executed. The various actions within method 600 can be performed in a different order, or concurrently, in the order presented. Still further, in some embodiments, some of the actions of 歹J in the sixth circle are ignored from method 6〇〇. The method 600 begins at 61 〇, where a data pattern (mailing and address value is received from an rfid card in the memory card slot. The data ❹ (4) corresponds to (4) the storage command f material value, and the address value corresponds to The command address value is hidden. In some embodiments, the mobile device only receives the data value, while in other embodiments, the mobile device only receives the address value. In some embodiments, when the RFID+ is first inserted In the memory card slot, the action of 610 occurs once. Whenever the mobile device establishes a hidden life 7, the mobile computing device can use the address and the data value. In other embodiments, each RFID card When inserted into the memory card slot, action 610 occurs. In still further embodiments, the data patterns may be the same or different, and the address values may be the same or different. 21 201023662 At 620, memory The card access command's tribute block will be populated by the data pattern so that the command is converted to the smart card on the RFm card. The data pattern can be written as a hidden command data value and written to the data block. Bit (Fig. 5). At 630, one of the memory card access commands will be filled with the address value's step-by-step so that the command is converted to the smart card controller. In some implementations In the example, only one of 620 or 63 is used. (4) In some embodiments, the existence of the hidden command is represented by the data sheet alone or by the address value alone. At 640, the memory card is accessed. The data block of the command is filled with a command string to specify a purpose other than memory card access. For example, the command substring can be written to the data field as a command for the smart card controller. Index 54. This command can be used for any purpose. For example, one or more hidden commands can have the sole purpose of maintaining power to the memory card slot so that the RFID card continues to receive power. φ At 650, The data barrier of the memory card access command is filled with a PIN lock to authenticate the access of the RFID card that is lightly coupled to the memory card slot. In some embodiments, a password is included in each of the hidden Command data in the block. In other concrete In the example, a password is only included at the beginning of the exchange. At 660, the memory card access command is sent to the RFID card coupled to the memory card slot. For example, a mobile computing device (11 〇, 1, 2)) The memory card access command can be sent to an RFID card (120, pictures 1, 3, 4) in the memory card slot (112, pictures 1, 2). The RFID card includes record 22 201023662 The memory card controller (340, Fig. 3) converts commands based on data intercepts filled in method 600. Figure 7 shows a flow chart in accordance with various embodiments of the present invention. In the example, the method paste can be used by an ID card in a memory card slot. In some embodiments, 'method 7 (10) or T portion is 'received' by a memory card controller within the memory card compatible RFID + Execution 'and in other embodiments, the square & 700, or part thereof' is performed by the software. The various actions in method 7 can be performed in the order presented, in a different order, or concurrently. Further, in some embodiments, some of the actions listed in Figure 7 are ignored from method 700. The method 700 begins at 71 ,, where a memory card access command is received from the mobile device via the host interface. The action of the 71〇 corresponds to the memory card slot in the mobile computing device (RFm card, which receives a memory card access command. • At 720, the memory card controller checks the criteria in the memory card access command' To determine whether the memory card access command should be converted into a smart card controller resident on the RFID card. The criterion can be either - hidden command data value or - hidden command address value - or both. If there is a - criterion match, then the - hide command and at least part of the memory card access command will be converted at 74. If no criteria are met, no hidden command will be presented, and at 75 ( Performing a memory access. Figure 8 shows a flow 23 in accordance with various embodiments of the present invention. 201023662 = In some embodiments, the method _ can be used in a card. In the embodiment, the method_, ^ part is performed by the memory card controller in the RFID card, and in other specific embodiments, the method is just, or part of it, is performed by the body. Various actions in 800 Executed in the order presented, in a different order, or simultaneously. Further in some embodiments, it is omitted in Figure 8. Some of the actions in Figure 8 will be from the method method. 800 begins at 810, wherein a memory card access command is received from the sway computing device via a host interface. If the memory card write command is determined to be a _hidden command, then the handler is rated to 8 Otherwise, the memory write is performed at 830. At 840, the hidden command is converted to the smart card controller. If the hidden command at (4) is judged to be "read", the handler continues at 86 ' 'otherwise 'It is considered to complete the hidden command handler. In the meantime, the memory card controller will take the non-memory data from the smart card_me, and the memory card read command will be received from the mobile computing device. The non-memory data is then passed back to the mobile computing device. Method 800 illustrates how a mobile computing device can perform reading from a smart card controller within a memory card compatible RFID card. hair Layout - a memory card write command with a hidden command, the hidden command has a status check indicating the read, and then the mobile computing device issues a memory card read command. The process in the card, the sequential receive The hidden command 'recognizes it as a read and then passes the data back to the mobile computing device in response to the memory card read command following 24 201023662. Figure 9 shows a display according to various embodiments of the present invention. In some embodiments, the method _ can be used in the note: slot: the card. In some embodiments, the method, or part of it, is the wisdom in the rfid card. The card controller executes, and in other specific implementations, methods, or portions thereof, is executed by the software. The various actions in the method 900 can be in the order of the presented, in a different order, or simultaneously. Execution. Further, some of the actions listed in Figure 9 in some of the Zhao embodiments are ignored from Method 9; The method 900 begins at 91 ,, where a smart card access command receives a command from the memory card controller - the command corresponds to a hidden command received by the memory card controller. At 95 (), the smart card controller determines if the command is a "dummy" command that is primarily used to maintain power to the memory card slot. If not, the smart card function specified in the command will be executed at 930. If so, ignore the command at 96 。. The method 900 can allow a memory card compatible RFID card within the memory card slot to remain powered while the memory card slot within the host device is being removed to save power. This is a cooperative effort between constructing a hidden command in the software within the memory card access command, a memory card controller that converts the hidden command to the smart card controller, and a smart card controller that ignores the command. According to the specific embodiment represented by FIG. 3A, the manner of providing power to the R]FID also provides power to the 25 201023662 smart card controller, thereby allowing the use of a small inductive device, as shown in Figures 3 and 4. Like. Figure 10 shows a flow diagram in accordance with various embodiments of the present invention. In some embodiments, method 1 can be used by an RFID card in a memory card slot. In some embodiments, the method 9〇〇, or a portion thereof, is performed by a memory card controller within the RFID card, while in other embodiments, the method 900, or portions thereof, is performed by The software is executed. The various actions in method 9 can be performed in the order presented, in a different order, or concurrently. Further, in some embodiments, some of the actions listed in Figure 10 are ignored from Method 1〇〇〇. Method 1000 begins at 1010 with a memory card controller receiving a hidden command from a touch computing device. If at 1020, the memory card controller determines that the hidden command is about to be converted to the smart card controller, the command is converted at 1030. If the command is not ready to be converted, then • the memory card controller does not convert the command; however, at 1 to 40 the memory card controller can take other actions based on the hidden command. For example, the memory card controller can modify the clock signal provided to the smart card controller. Also as an example, the memory card controller can assert a reset signal to the smart card controller. Still (4) as an example, the memory card controller can modify the power transfer to the smart card controller. In a particular embodiment represented by the πth diagram, the memory card controller can modify the power transfer to the smart card controller. Power transfer can be modified by removing power, applying power, circulating power, and the like. 26 201023662 The step of modifying the power transfer to the smart card controller can be a collaborative effort between the host computing device and the memory card controller within the RFID card. For example, the power supplied to the memory card slot can be maintained by supplying a virtual hidden command to the RFID card, as described above with reference to Figure 9. When power is continuously supplied to the memory card slot, a hidden command can be used to enable the memory card controller to modify, apply, or recycle power to the smart card controller.修改 Modification of power delivery may allow for additional security features. For example, turning off the power to the smart card controller will show that the smart card is inactive, and therefore allows the inferior reader to avoid unnecessary reading of the card. Since the antenna is too small to provide sufficient power to the smart card controller, in order to properly operate the card reading function, it is necessary to obtain power from the memory card controller or from the host interface. Figure 11 shows a method for authenticating a mobile computing device to one or more functions within a memory card compatible RFID card. The method i 1 starts 方块 starting at block U1〇, where an activation code is received at the RFID card from the mobile computing device. At 1120, the received activation code is compared to the code stored in the RFID card. If the activation code matches, the RFID card receives a password from the mobile computing device at i 14 , and stores the password in the RFID card at 115 以 for later use. If the activation codes do not match, then at 1160 the RFID card determines if the number of allowed trials has been exceeded. If the number of allowable attempts has been exceeded, then the RFID card issuer is contacted at 117, and if the number of allowable attempts has not been exceeded, then the method will repeat the attempt until the start code is not matched to allow the number of attempts 27 201023662 Exceeding β When an RFID card is issued to a user, the executable method 110〇β, for example, the RFID card can be a mobile payment card (payment, which is issued by a financial institution. The user can be provided to start The code is to "activate" the RFID card. When the user successfully enters the activation code, the user is provided with a set of passwords that will be stored for use in future hidden commands. In an embodiment, multiple non-memory functions within the RFID card are authenticated using method 1100. For example, each of the plurality of non-memory functions may have a stored boot code, and each function has been activated separately. The separately activated functions may have different passwords, or the multiple functions may share a password. Although the invention has been described in connection with several specific embodiments' It is to be understood that modifications and variations can be readily made without departing from the spirit and scope of the invention, as those skilled in the art can readily understand. And the scope of the patent application.
