Benefits of technology
The patent describes a method and device for verifying compatibility between a contactless communication circuit and a proximity coupling device. The contactless circuit detects the initiation of a first anticollision process and responds by transmitting two communication protocol identifiers to cause a collision with the device. The device then transmits a single communication protocol identifier selected based on the first anticollision process. The contactless circuit can also transmit a circuit identification code and can support different applications, such as EMV and MIFARE Classic or MIFARE Classic+. The technical effect of this patent is to ensure compatibility between different applications and devices using contactless communication.
Problems solved by technology
The development of applications usable in contactless communications, between a proximity coupling device (PCD), for example, a contactless terminal (Contactless Reader), and a contactless integrated circuit (Proximity Integrated Circuit—PIC) or a contactless integrated circuit card (Proximity Integrated Circuit Card—PICC) generates new difficulties.
In particular, communications comply with evolving standards, which may raise problems of compatibility between different generations of devices or circuits.
However, this generates false rejections, that is, a card which would be capable of communicating with a reader is refused by said reader.

Embodiment Construction
[0028]The same elements have been designated with the same reference numerals in the different drawings, unless the context indicates otherwise.
[0029]For clarity, only those steps and elements which are useful to the understanding of the embodiments which will be described have been shown and will be detailed. In particular, the exchanges between the proximity coupling device and a proximity integrated circuit once the communication has been completed have not been detailed, the described embodiments being compatible with usual exchanges.
[0030]The embodiments are described while taking as an example a contactless card forming a proximity integrated circuit card (PICC) and a contactless reader forming a proximity coupling device (PCD). Embodiments, however, may more generally apply to any device used as a proximity coupling device and to any contactless communication integrated circuit where similar problems are posed. Further, although reference is made to payment applications, the ...

A contactless communication circuit (card) communicates with a proximity coupling device (reader). The card hosts at least two applications. The card detects initialization of a first anticollision process by the reader and transmits two communication protocol identifiers in response to the detection of the first anticollision process. The communication protocol identifiers are associated with respective applications supported by the card. Transmission of the two communication protocol identifiers triggers detection of a collision by the reader.
