Identification card
Technical Field
The invention relates to the technical field of intelligent identification cards, in particular to an identification card.
Background
Common smart cards are classified into single interface cards and dual interface cards. The single interface means that the intelligent card is in a contact or non-contact mode with external information communication. The contact smart card generally uses ISO7816 standard, i.e. IC card with 8 metal contacts. Contactless smart cards generally use NFC or RFID standards and utilize passive electromagnetic coils to communicate with the outside world. The dual-interface card refers to a card having both contact and non-contact communication modes. A typical application is the use of a joint-banking flash payment card commonly used by banking systems. The IC card part can be used for transacting services such as balance inquiry, deposit and withdrawal and the like, and the non-contact NFC part can be used for consuming and recharging change. Two operation modes of the dual-interface card can share operation data and a storage area.
The various smart cards have been widely used in real life. However, in the prior art, it is generally required to use a dedicated read-write device to read data from the smart card (for example, to inquire the balance in the card) or write data into the smart card (for example, to recharge the smart card), which is inconvenient. For example, if a card user wants to add value to his/her contactless smart card, he/she must go to a teller machine designated by the card issuer, which is very inconvenient.
Therefore, how to make the ordinary user more conveniently read and write the data of the smart card is a technical problem that needs to be solved by the technical personnel in the field.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
In the embodiment of the invention, the Bluetooth chip and the corresponding operation interface are added on the basis of the existing identification card, so that other Bluetooth devices including Bluetooth reading heads, smart phones, smart tablets or personal computers and other devices with Bluetooth communication technology can operate the identification card, including inquiring information in the identification card or modifying information in the identification card and the like. The technology breaks through the limitation that the traditional single-interface or double-interface intelligent identification card can only be operated by special equipment, and widens the use scene of the intelligent identification card. The method has important practical significance for services such as intelligent identification card air recharging, mobile POS and the like. Specific implementations are described in detail below.
Example one
In the first embodiment, referring to fig. 1, the identification card 10 may include an identification card standard chip 101, a bluetooth chip 102, and a power module 103. The standard chip of the identification card may be a single interface chip or a dual interface chip, in short, a contact chip or a non-contact chip that can be produced by various manufacturers in the prior art, and the like. Various data in the identification card are still stored in the identification card standard chip 101. For convenience of description, the identification card standard chip is hereinafter simply referred to as "standard chip".
The bluetooth chip 102 is provided with at least one first operation port for connecting with an operation port provided by the standard chip 101. Among them, regarding the operation ports provided by the standard chip 101, the number, name, etc. of the operation ports provided may be different for the standard chips of the identification cards produced by different manufacturers, and some standard chips may be provided with only external pins (for example, contacts on a contact chip, etc.) for performing data communication with external devices, and some standard chips may be provided with internal pins for performing data communication, etc. Therefore, the specific operation port to which the bluetooth chip is connected can be determined according to the actual situation of the standard chip used. For example, on a certain contact chip, eight metal contacts such as C1-C8 on the surface can be used as external pins to perform contact communication with the outside, and at this time, the bluetooth chip may include three first operation ports respectively connected to the C2-RST, C3-CLK, and C7-I/O ports of the contact chip, so that data communication can be performed between the bluetooth chip and the standard chip.
That is, in the embodiment of the present invention, two chips are included in one identification card, one of the two chips is an identification card standard chip produced according to the standard of the prior art, and includes a contact chip and/or a contactless chip, and the other chip is a bluetooth chip. Data communication can be carried out between bluetooth chip and the standard chip, and bluetooth chip can carry out data communication with the external control equipment who has bluetooth function again, consequently, just can realize the data communication between the external control equipment who has bluetooth function and the identification card standard chip through the bridging of bluetooth chip. Thus, even if a special standard chip reading and writing device is not used, the reading and writing of the identification card can be realized, and the device only has the Bluetooth function.
In a specific implementation, a bluetooth protocol is used for communication between the bluetooth chip and the external control device having a bluetooth function, and a serial port protocol is generally used for data processing and communication between the standard chip and the bluetooth chip (of course, the standard chips produced by different manufacturers may use different protocols). For this reason, in the embodiment of the present invention, the bluetooth chip 102 may further include:
the first conversion module is used for recoding the first data/instruction according to the data protocol of the standard chip of the identification card when receiving the first data/instruction sent by the external control equipment through the Bluetooth protocol;
the first transmission module is used for transmitting the recoded first data/instruction to the identification card standard chip for processing through the first operation port;
the second conversion module is used for recoding second data/instructions sent by the identification card standard chip according to a Bluetooth protocol when the second data/instructions are received through the first operation port;
and the second transmission module is used for sending the recoded second data/instruction to external control equipment for processing through a Bluetooth protocol.
That is, the bluetooth chip 102 needs to perform data bridging and also perform data encoding format conversion, so that the standard chip 101 and the bluetooth chip 102 can correctly recognize data/instructions from each other.
It should be noted that the power supply module 103 on the identification card can simultaneously supply power to the bluetooth chip 102 and the identification card standard chip 101. Furthermore, the power supply module 103 may be in the form of a battery, which may or may not be rechargeable. In most cases, data in the identification card does not need to be read or written, so that, to achieve the purpose of power saving, the identification card may further include a power supply control module, and the bluetooth chip 102 may further include a second operation port, where the bluetooth chip 102 is connected to the identification card standard chip through the second operation port. Thus, the power supply control module may be configured to set the power supply line from the power module to the standard chip 101 in a disconnected state in a state without data/instruction transmission, and set the power supply line from the power module to the standard chip 101 in a connected state when the bluetooth chip 102 receives the first data/instruction sent by the external control device through the bluetooth protocol. That is to say, only under the condition that data/instructions need to be transmitted, the power module will supply power to the standard chip 101, and the standard chip 101 will not consume the electric energy of the power module in most other time periods, so that the purpose of saving power can be achieved.
In the above case, the power supply module is always supplying power to the bluetooth chip 102, because the bluetooth chip 102 needs to monitor data/instructions from the external control device in real time. However, in order to further save power, a physical control key may be further added to the identification card 10, the physical control key may be connected to the bluetooth chip 102, and in a state without data/command transmission, the bluetooth chip 102 may be in a sleep state, and meanwhile, the bluetooth chip 102 may further include:
and the wake-up module is used for switching the bluetooth chip 102 into a working state when the physical control key is operated.
That is to say, in the above manner, in most cases, the standard chip 101 does not need the power module to supply power to the standard chip 101, and although the power module always supplies power to the bluetooth chip 102, the bluetooth chip is standby in a sleep state with very low power consumption most of the time, only when the physical control key is operated, the bluetooth chip 102 is switched to a normal operating state, at this time, the bluetooth chip 102 may monitor data/instructions from the external control device, but the power module does not yet supply power to the standard chip 101, and only when the bluetooth chip 102 monitors data/instructions from the external control device, the power supply line between the power module and the standard chip 101 is conducted through the power supply control module to supply power to the standard chip 101. After the whole communication process is finished, the bluetooth chip 102 waits for continuing the external command according to the predetermined program, and if no external command exceeds a certain time, for example, 10 minutes, the bluetooth chip 102 enters a sleep state with extremely low power consumption for standby.
In order to better understand the embodiment of the present invention, each functional module in the specific implementation provided in the embodiment of the present invention is described in more detail below by using a specific example.
Referring to fig. 2, a schematic structural diagram of an identification card according to a specific embodiment of the present invention is shown, wherein the standard chip of the identification card may be a dual-interface identification card supporting the ISO7816 standard, and it may perform contactless communication with the outside through an NFC antenna, or may perform contact communication with the outside through C1-C8 metal contacts (not shown in fig. 2) on the surface of the standard chip. Alternatively, the identification card standard chip may be a single interface identification card capable of only contact communication or only supporting non-contact communication. The Bluetooth chip is connected with a built-in rechargeable or non-rechargeable battery. The Bluetooth chip is led out of at least one first operation port to be connected to the operation port of the identification card. The Bluetooth chip is connected to the power supply control module through the second operation port, and the power supply control module can be switched on and off by the power supply of the standard chip. In addition, a physical control key (for example, a film button or the like) is also placed on the identification card, and is connected to the bluetooth chip to realize functions such as system wakeup and the like.
The first embodiment of the present invention is described above, and according to this embodiment, two chips may be provided in the identification card, where one is a standard chip storing specific data, and the other is a bluetooth chip, and as long as the external control device has a bluetooth function, the external control device can perform read/write operation on data in the standard chip through the bluetooth chip, and does not rely on a dedicated standard chip read/write device, so that the usage scenarios of the identification card are widened.
Example two
In the first embodiment, two chips are arranged in an identification card in a gluing method, and in the second embodiment, a bluetooth function can be directly integrated into a standard chip of an existing identification card, so that the same identification card can only comprise one chip, but the chip can read and write data through a special data reading and writing device in a traditional manner, and can also read and write data through an external control device with a bluetooth function by the integrated bluetooth function.
Referring to fig. 3, a second embodiment of the present invention provides another identification card 30, where the identification card includes a chip 301 and a power module 302, and the chip 301 includes an identification card standard module 3011 and a bluetooth module 3012;
the identification card standard module 3011 stores identification card data;
the bluetooth module 3012 includes:
at least one first operation port, which is used for connecting with the operation port provided by the standard chip of the identification card;
the first conversion module is used for recoding first data/instructions sent by external control equipment according to the data protocol of the identification card standard module when the first data/instructions are received through a Bluetooth protocol;
the first transmission module is used for transmitting the recoded first data/instruction to the identification card standard module for processing through the first operation port;
the second conversion module is used for recoding second data/instructions sent by the identification card standard module according to a Bluetooth protocol when the second data/instructions are received through the first operation port;
and the second transmission module is used for sending the recoded second data/instruction to external control equipment for processing through a Bluetooth protocol.
In addition, in order to achieve the purpose of power saving, the chip 301 may be in a sleep state in a state without data/command transmission, meanwhile, the identification card may also have a physical control key 303 connected to the chip 301, and the chip 301 may further include a wake-up module for switching the chip 301 to an operating state when an event occurs that the physical control key 302 is operated.
It should be noted that, this embodiment is equivalent to integrating a standard chip and a bluetooth chip together, so as to obtain a more comprehensive functional chip, where the standard chip may be a single-interface chip or a dual-interface chip. Under the condition that the standard chip is a double-interface chip, the integrated chip is equivalent to a multi-interface chip, the multi-interface card chip 301 is provided with a standard contact interface ISO7816 and can operate the identification card through an external card reader, and meanwhile, the multi-interface card chip 301 is provided with a standard non-contact NFC antenna interface and is connected with the coil 302, so that the external NFC card reader can operate the identification card through a non-contact mode. In addition, the multi-interface card chip 301 integrates a bluetooth module, and the identification card can be operated by a device such as a mobile phone having bluetooth connection capability.
