Abstract

A system for dynamic pairing between a first peripheral, which can dialogue with a memory card, and a second peripheral, which is connected to a computer. The first peripheral is configured to read the data contained in the memory card, to receive via a first communication channel a first item of information emitted by the second peripheral, and to emit via a second communication channel a second item of information. The second peripheral is configured to emit via the first communication channel the first item of information and to receive via the second communication channel the second item of information. The value of this second item of information conditions the authorization to open a bidirectional communication channel between the first and the second peripherals.
