Description

Display card with security verification

technical field

The present invention relates to a flexible card with safety verification, in particular to a display card that can actively read and display data on an intelligent integrated circuit, and provides the smart integrated circuit with a power management module. required power and controls.

Background technique

With the advancement of technology, many transaction and payment methods have been gradually replaced by integrated circuit (Integrated Circuit, IC) cards. For example, credit cards, debit cards, telephone cards, stored-value cards, etc. are all common IC cards at present, and generally used IC cards can be roughly divided into contact interface, contactless interface and non-contact interface according to the way of storing and reading data. There are three types of interface and composite interface.

The IC card with the so-called contact interface uses metal contacts to access data, such as general chip financial cards, etc., while the IC card with the so-called non-contact interface uses induction to access data, such as for the public Stored-value cards or e-money wallets for transportation vehicles, etc. Later, due to the emergence of many different types of cards on the market, IC cards with so-called composite interfaces were also developed, which integrated the functions of various requirements such as credit cards, financial cards, electronic money wallets, and stored value cards. In a single IC card, users only need to hold a single card to enjoy diversified services.

However, in the past, electronic smart cards did not have a display function, so that consumers had to read the card through bills or other machines before they could know the information (such as the balance). Therefore, an integrated circuit card with a display device was released on the market. , allowing the user to display the current usage message.

Please refer to Fig. 1, the traditional IC card with a display includes: a display 10, a communication interface 11, a microprocessor 12, a display drive circuit 13, a boost circuit 14, a rectifying and stabilizing circuit 15, and a non-volatile readable memory 16. Wherein, after the microprocessor 12 receives the signal from the communication interface 11, the data can be stored in the non-volatile rewritable memory 16, and the data can be converted into the driving signal of the display 10 through the display driving circuit 13. The voltage circuit 14 converts the DC power generated by the rectifying and stabilizing circuit 15 into the driving voltage of the display 10, so that the user can directly check the data on the display 10; in addition, the microprocessor 12 also transmits the corresponding signal through the communication interface 11 For external card readers.

Moreover, the traditional communication interface 11 is set as a composite design combining a contactless radio frequency smart card integrated circuit 17 and a contact smart card integrated circuit 18, and the inside of the integrated circuit card is based on different contactless radio frequency smart card integrated circuits 17 or contact smart card integrated circuits. The integrated circuit 18 is used to obtain the required driving power source.

The contactless radio frequency smart card integrated circuit 17 is designed with an antenna 19 inside, and the antenna 19 will receive the radio frequency signal from the external card reader, and the coupled signal will be demodulated through the communication interface 11. On the other hand, the coupled signal will be rectified The voltage stabilizing circuit 15 generates a DC power supply to supply internal required voltage. The contact smart card integrated circuit 19 receives the digital serial signal from the external card reader and decodes it for the microprocessor 12 to read. The external card reader also supplies DC power for internal use via the contact smart card IC 19 .

However, this traditional integrated circuit card does not have a power generator, and it must rely on the induction current generated by receiving external signals to cooperate with the internal boost circuit and rectification and voltage stabilization circuit to drive data communication and display. Users cannot obtain integrated circuit cards by themselves. The information in the card affects the convenience of using the traditional display card.

Therefore, another integrated circuit card has been developed on the market that hopes to overcome the above-mentioned deficiency. Please refer to FIG. 23 and a power generator 24; wherein, the display circuit 21 is connected to the flexible display 20, and the communication interface 22 is connected to the display circuit 21 via the smart card integrated circuit 23, and the smart card integrated circuit 23 performs security verification, and the communication interface 22 needs After the security verification is successful, the data can communicate with the display circuit 21 through the smart card integrated circuit 23 .

Furthermore, the display circuit 21 has a display driver 211 for driving the flexible display 20 and a display controller 212 for controlling the display driver 211, wherein the display driver 211 is connected to the flexible display 20, and the display controller 212 It is connected to the display driver 211 and the smart card integrated circuit 23 . In addition, the smart card integrated circuit 23 has a security module 231 and a storage unit 232, wherein the security module 231 is used to perform security verification to prevent hackers from intruding, and the data of the storage unit 232 can only be accessed after the security verification is successful. Moreover, the power generator 24 is respectively connected to the display circuit 21, the communication interface 22 and the smart card integrated circuit 23, and receives the radio frequency signal through the communication interface 22, and supplies the required working voltage according to the received radio frequency signal.

However, although this kind of integrated circuit card receives radio frequency signals based on the communication interface to drive the internal power generator to generate the required operating voltage, it must also cooperate with other devices such as card readers to generate operating voltage for data display. The user cannot independently obtain the stored information in the card without a matching device, and the voltage of the power generator is often unstable, resulting in poor induction or data communication. In view of the deficiencies in the use of traditional integrated circuit cards with displays, it is necessary to improve and innovate flexible display integrated circuit cards.
