Description

Memory card with smart chip

The present invention relates to a memory card, and more particularly to a memory card having a smart wafer.

With the development of mobile communication technologies, such as 3G (3rd-Generation), WiMAX (Worldwide Interoperability for Microwave Access), LTE (Long Term Evolution) and other mobile communication technologies, and with the development of wireless communication technologies, for example: Near Field Communication (NFC) technology, thus developing a mobile payment mechanism (Mobile Payment), allowing users to easily pay for mobile consumption purposes, and thus various mobile payment mechanisms that implement mobile payment mechanisms, Payment media has therefore been continuously developed.

Memory card (such as secure digital card, ie SD card) is a memory device based on semiconductor storage technology. It has high memory capacity, fast data transmission, small size, easy portability and high security. It is widely used. Used on portable electronic devices. The existing smart SD card (Smart SD card) combines the smart card chip and the storage function, and the mobile communication device can be implemented by SWP (Single Wire Protocol), CLF (Contactless Frontend), contactless communication module. And the antenna communicates with the smart SD card. However, with such a smart SD card, the mobile communication device must have a CLF and an antenna, and cannot implement contact transactions through an external device (for example, a 7816-3IC reading device). It is even more difficult to complete contactless transactions when the mobile communication device is under-powered.

Another smart SD card is to place the smart card chip, storage function, antenna and SD controller on an SD card, which can reduce the requirements for mobile communication devices, but for metal case phones or other mobile phone structures. When the non-contact signal is masked, the contactless transaction cannot be completed. Moreover, such a design cannot be contacted by an external device, for example, using a 7816-3IC reading device.

Moreover, the conventional smart SD card is different in shape from the standard financial wisdom card, and cannot adapt to the existing standard financial smart card reading device. At the same time, because the smart SD card is limited in size, even in an ideal environment, The non-contact performance of smart SD card products is still much worse than the standard dual interface (for contact and contactless communication) smart cards.

One of the objectives of the present invention is to achieve more action payment functions by combining a memory card of a smart chip to make up for the deficiencies of the prior art, thereby achieving the purpose of multi-purpose.

Another object of the present invention is to make the memory card incorporating the smart chip more suitable for the existing contact and contactless smart chip reading device, in addition to the non-contact communication capability.

To achieve the above and other objects, the present invention provides a memory card with a smart chip, comprising a substrate and a smart chip disposed on the substrate, a memory card controller and a memory card standard connection terminal group, the characteristics thereof The smart chip connection terminal group is connected to the smart chip connection terminal group, and the smart chip is connected to the memory card controller, and the memory is connected to the smart chip. The card standard connection terminal group and the smart chip connection terminal group are exposed on the memory card.

In an embodiment of the present invention, the substrate further includes: an inductive antenna connection terminal group connected to the smart chip and connected to the sensing antenna independent of the external memory card; an internal sensing antenna module; and one day The line signal processing module is connected to the internal sensing antenna module, the memory card controller and the sensing antenna connection terminal group, wherein the antenna signal processing module has a signal processing unit and a switching unit, and the signal processing unit Processing the signal received by the internal sensing antenna module, the switching unit is connected to the sensing antenna connection terminal group to output the processed signal to the smart chip, and the switching unit is configured to be connected in the sensing antenna connection terminal group The external sensing antenna disconnects the connection path between the signal processing unit and the sensing antenna connection terminal group.

In an embodiment of the present invention, the memory card controller is configured to control the switching unit to turn on the signal processing unit and the sensing antenna connection terminal group when the memory card standard connection terminal group receives an external input voltage. Connection path between.

In an embodiment of the invention, the signal processing unit includes a preamplifier processor for amplifying the signal received by the internal sensing antenna module.

In an embodiment of the invention, the sensing antenna connection terminal group is exposed on the memory card and located between the memory card standard connection terminal group and the smart chip connection terminal group.

In an embodiment of the invention, the smart chip connection terminal group is composed of a VCC terminal, an RST terminal, a CLK terminal, an IO terminal, and a GND terminal.

Therefore, the effect of using the technical features of the case is as follows:

1. The conventional smart SD card cannot use the existing contact reading device because there is no direct contact (smart chip connection terminal group) for the smart chip communication protocol, such as: the bank ATM cash machine, in this case After adding the smart chip connection terminal group (7816 interface) to the external memory card of the smart chip, the existing contact reading can be directly inserted through the adapter (such as an external card sleeve to simulate the size of the existing card). Take the equipment, because the smart chip connection terminal group in this case is consistent with the layout and function of the IC contact of the existing bank card issuance system. After the smart SD card is inserted into the adapter, the overall length and width of the smart SD card are compared with the standard bank financial IC card. The same, and the overall thickness does not exceed 1mm, can smoothly use the contact reading device of the existing bank card issuing system, will not be stuck, and the contact reading device of the existing bank card issuing system can pass through the original reading head, The personalized data is transmitted to the adapter and directly transmitted to the smart SD card, which can realize the production of a large number of cards on the existing distribution equipment without further conversion.

2. The existing smart SD card cannot directly use the 7816 interface communication protocol because there is no direct contact, so it is impossible to use a payment device such as a contact card reader, and add a smart chip connection terminal group (7816 interface) outside the smart SD card. Through the adapter, the front end of the adapter can be inserted into the IC card socket of the device such as the credit card machine, and the payment transaction can be completed without other agreement conversion, for example, to the current financial card credit card.

3. After adding the smart chip connection terminal group (7816 interface) outside the smart SD card, in the contact payment process of the smart SD card combined with the adapter, the data is directly transmitted from the terminal device such as the credit card machine to the smart SD through the adapter. The smart chip in the card does not need to pass through the memory card controller, avoiding the component damage caused by the inconsistent working voltage between the memory card controller and the ordinary IC card, and eliminating the need for additional voltage conversion on the memory card or the adapter. The cost of the module and the possibility that the memory card or the adapter will increase in thickness due to the setting of the voltage conversion module.

4. After adding the smart chip connection terminal group (7816 interface) outside the smart SD card, the information in the smart chip can still be retained by retaining the contact structure of the original smart SD card and the connection relationship between the memory card controller and the smart chip. It is transmitted from the memory card standard connection terminal group through the memory card controller, so it can still be inserted into the mobile phone to realize online transaction through the operation on the mobile phone.

5. After adding the smart chip connection terminal group (7816 interface) outside the smart SD card, since the memory card standard connection terminal group of the original smart SD card is retained, the existing external device can still be inserted as the mobile storage device. .

In order to fully understand the objects, features and advantages of the present invention, the present invention will be described in detail by the following specific embodiments and the accompanying drawings.

First, please refer to FIG. 1 , which is a functional block diagram of a memory card with a smart chip according to an embodiment of the invention. The memory card with the smart chip is a memory card product for adding a substrate 100 to the outer casing. The appearance of the memory card product can be various types of memory cards when the thickness permits, and is Micro in the present invention. The SD card is taken as an example. In the embodiment of the present invention, the substrate 100 includes: a smart chip 110, a memory card controller 120, a memory card standard connection terminal group 122, and a smart wafer connection terminal group 112. The smart chip connection terminal group 112 on the substrate 100 is a connection terminal disposed under the communication protocol specification of the smart chip 110. For example, when the memory card with the smart chip is an SD card, the smart chip connection The terminal group 112 is composed of VCC terminal 112a, RST terminal 112b, CLK terminal 112c, IO terminal 112d, and GND112e terminals.

As shown in FIG. 1, the smart chip connection terminal group 112 is connected to the smart chip 110, and the smart chip 110 is connected to the memory card controller 120. In addition, although not shown in FIG. 1, the memory card standard connection terminal group 122 and the smart chip connection terminal group 112 are exposed on the memory card, so that the memory card standard connection terminal group 122 can be used for the memory phantom. The group 130 plays the original access function, and the smart chip connection terminal group 112 can be used for the external adapter card to guide the terminals to the position of the smart chip of the original smart chip card (refer to the following fourth figure). On the other hand, the smart chip connection terminal group 112 can also be directly arranged as the position of each contact terminal of the smart chip, and can be directly used after the adapter card is connected without being connected to the terminal ( See the third figure below).

2 is a functional block diagram of a memory card with a smart chip in another embodiment of the present invention. In this embodiment, the substrate 100 further includes: an inductive antenna connection terminal group 140, an internal inductive antenna module 150, and an antenna signal processing module 160. The sensing antenna connection terminal group 140 is connected to the smart chip 110 and is connected to the sensing antenna outside the memory card, that is, the sensing antenna connection terminal group 140 is used when the memory card of the present invention is mounted on the riser card. The sensing antenna on the adapter card can be connected, so that the signal received by the sensing antenna on the adapter card can be input into the smart wafer 110. The antenna signal processing module 160 is connected to the internal sensing antenna module 150, the memory card controller 120, and the sensing antenna connection terminal group 112.

It is to be noted that the antenna signal processing module 160 includes a signal processing unit 162 and a switching unit 164 for processing and switching signals sensed by the internal sensing antenna module 150 and signals sensed by the external sensing antenna.

The signal processing unit 162 is configured to process the signal received by the internal sensing antenna module 150. For example, since the internal sensing antenna module 150 on the memory card is small, the signal processing unit 162 can include a pre-processing. The amplifier is configured to amplify the signal received by the internal sensing antenna module 150.

The switching unit 164 is connected to the sensing antenna connection terminal group 140 to output the signal processed by the signal processing unit 162 to the smart wafer 110. The switching unit 164 is configured to disconnect the connection between the signal processing unit 162 and the sensing antenna connection terminal group 140 when the sensing antenna connection terminal group 140 is connected to the external sensing antenna. For example, when the sensing antenna connection terminal group 140 is not connected to the external sensing antenna, the connection path between the signal processing unit 162 and the sensing antenna connection terminal group 140 is turned on.

The control of the switching unit 164 allows the internal and external antennas to be used correctly, so that the sensing signals are smoothly received by the smart wafer 110. For example, when the memory card of the present invention is inserted into the electronic device and receives an external voltage, the external voltage is transmitted to the memory card controller 120 through the memory card standard connection terminal group 122, and the memory card controller 120 and can be configured to control the switching unit 164 to enable the switching unit 164 to open a connection path between the signal processing unit 162 and the sensing antenna connection terminal group 140. Conversely, when the memory card of the present invention is not inserted into the electronic device ( When the electronic card device is not inserted into the electronic device, the memory card controller 120 does not receive the voltage signal, so the switching unit 164 is not controlled, thereby maintaining the uncontrolled voltage of the switching unit 164. status.

For example, the switching unit 164 can use a switching element that can maintain a short circuit condition when the voltage is applied (ie, the memory card controller 120 gives a control signal), so that the sensing signal of the internal sensing antenna module 150 can pass through the signal processing unit. The 162 is processed and output to the smart wafer 110. When the switching unit 164 is not subjected to a voltage, the switching element generates an off state, thereby enabling the smart chip 110 to receive a signal sensed by the sensing antenna outside the memory card.

Next, please refer to FIG. 3, which is a schematic diagram of a memory card with a smart chip mounted on an adapter according to an embodiment of the invention. In this embodiment, the adapter 200 carries (for example, embedded or plugged) a memory card 300 with a smart chip, and the smart chip connection terminal group 112 (not shown) can be used. The smart chip terminal 220 on the adapter 200 is connected to the external sensing antenna module 210 on the adapter 200 through the sensing antenna connecting terminal group 140 to complete the small card conversion into a large card. It can be used as a general chip card, and it can also be compatible with the reading devices of existing smart cards (such as IC financial cards, leisure cards, etc.).

4 is a terminal configuration diagram of a memory card with a smart chip according to an embodiment of the present invention. The sensing antenna connection terminal group 140 is exposed on the memory card, and the smart chip connection terminal group 112 is located. The sensing antennas are connected between the terminal groups 140.

In summary, the smart chip connection terminal group on the memory card of the present invention can be used as an external adapter to transfer the memory card into a large card without using a new device to read, which not only solves the problem of the existing SD card. The problem is to expand the use of smart SD cards to make up for the shortcomings in the prior art. In addition, in the configuration of the present invention, the memory card with the smart chip can be used for a portable or wearable electronic device such as a mobile phone, a tablet computer, a smart watch, etc., and then the user can conduct electronic transactions for the purpose of multi-purpose.
