Display card with a protection chip

Abstract

The invention relates to a display card with a protection chip. The display card is provided with a card structure in which an electronic system is arranged. The electronic system comprises a display and an input device exposed out of the card structure. The input device comprises an operation area for inputting verification data. The display and the input device are electrically connected with a microprocessor. The microprocessor is equipped with an authentication module for verifying whether verification data is correct and is electrically connected with a control unit. The control unit is connected with a security chip storing data and a communication interface for inputting / outputting data in cooperation with a reading device in a connected manner. The control unit receives a control signal provided by the microprocessor and selectively connects or disconnects the security chip with the communication interface. Accordingly, whether a card holder is a valid user is confirmed before the card is used, thereby greatly improving the use security of a transaction IC card.

Description

technical field [0001] The invention relates to a flexible display card with a protection mechanism, in particular to a display card that needs to input verification data to confirm the legitimacy of the cardholder before transaction. Background technique [0002] 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. [0003] 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 a...

Problems solved by technology

[0005] However, whether it is a general integrated circuit card without a display device or a new version of an integrated circuit card with a display device, when it is used in a transaction, it is nothing more than directly debiting the stored value of the integrated circuit card without any other Otherwise, it is like a credit card will be connected to the bank, and then the cardholder will sign on the receipt to complete the so-called transaction action. Although the general credit card will do the so-called signature confirmation, in the actual transaction situation, the general seller Most of them only check whether the signature is correct, but do not confirm the handwriting of the signature in detail. If the cardholder is not a legal user, it will often be impossible to prevent illegal users from stealing in the first place, which often results in Unnecessary trouble and financial loss for legitimate card holders

[0006] In view of the fact that traditional integrated circuit cards still have insufficient security in the use of transactions, it is necessary to improve and innovate the security mechanism of integrated circuit cards
