Embodiment Construction

[0025] In different drawings, the same elements are designated by the same reference signs.

[0026] For clarity, only those steps and elements useful for the understanding of the embodiments to be described are shown and detailed. In particular, the exchange between the proximity coupling device and the proximity integrated circuit after the communication is completed is not detailed, and the described embodiment is compatible with general exchange.

[0027] The embodiments are described using a contactless card forming a proximity integrated circuit card (PICC) and a contactless card reader forming a proximity coupling device (PCD) as examples. However, they are more generally applicable to any device used as a proximity coupling device and to any contactless communication integrated circuit in which similar problems are caused. In addition, although referring to payment applications, the described embodiments are applicable to applications of different attributes as long as the...

Abstract

The invention relates to a configuration of a transaction in a proximity circuit and specifically provides a method of configuring a contactless communication circuit hosting at least two applications compatible with different communication protocols, wherein, as a response to a first anticollision process initiated by a proximity coupling device, the circuit transmits two identifiers of the communication protocols to cause a collision on the side of the proximity coupling device.

Description

[0001] Cross references to related applications [0002] This application claims the priority right of French Patent Application No. 16 / 51712, the content of which is incorporated by reference in its entirety to the maximum extent permitted by law. Technical field [0003] The present disclosure relates generally to electronic circuits, and more specifically to contactless communication circuits. The present disclosure more specifically aims to select a communication mode between the contactless communication terminal and the contactless communication circuit. Background technique [0004] Contactless communication between a proximity coupling device (PCD) (such as a contactless terminal (contactless card reader)) and a contactless integrated circuit (proximity integrated circuit PIC) or a contactless integrated circuit card (proximity integrated circuit card PICC) The development of useful applications in China creates new difficulties. [0005] In particular, communications comply...
