Embodiment Construction

[0013] figure 1 is a functional diagram of the first embodiment of the present invention. In this embodiment, the bank card 100 is a contact smart card comprising a security chip 101 with a communication interface according to the ISO 7816 standard connected to a connector 102 comprising contact pads also defined by the 7816 standard (contact pads). The secure chip 101 is, for example, a chip that complies with the EMV standard and contains data with restricted access and other so-called public data. Restricted-access data requires the use of passwords or encrypted messages, whereas public data can be accessed for reading and / or writing by any reader conforming to the ISO7816 standard.

[0014] During a payment using the security chip 101, the bank card 100 is inserted into a security reader which verifies the PIN number entered by the card's holder in order to verify that the card holder is the correct card holder , followed by the exchange of secure information via encry...

Abstract

To allow the display of the latest transactions, a chip card 100c for secure transaction comprises at least one secure chip 101c, for example of EMV type, furnished with at least one communication interface so as to be able to communicate with a card reader so as to perform a transaction, an electronic display 103, an autonomous battery 104, a card reader circuit 150c connected to a communication interface of the secure chip so as to be able to access information contained in the secure chip so as to be able to display same on the display.

Description

technical field [0001] The invention relates to a bank card with a display screen. Background technique [0002] Bank cards have electronic chips for transaction security. The EMV standard was created by Europay, MasterCard and Visa, the acronyms involved in the definition of interoperability and security standards between smart bank cards. In order for a card to have EMV certification, the card must have a chip which itself is certified and has a contact-type interface according to the ISO7816 standard and / or a contactless interface according to the ISO14443 standard. To limit the risk of hacking, the EMV chip does not have any other communication interfaces. [0003] Furthermore, the manufacture of smart cards having a screen and one or more buttons for communicating with the card holder is also known. These cards are not currently widespread and are used to generate single use passwords for computer transactions. Such cards typically have a chip with a contact or cont...
