Abstract

The invention relates to a method and an apparatus for controlling communication between a terminal and a number of chip cards. Electromagnetic waves are continuously emitted by the terminal to form a communication zone within which communication between the terminal and the chip cards is initiated and sustained. After the sequence emitted by a first chip card, an identifier is generated in the terminal identifying the same chip card and is stored in the terminal.
