An anti-collision method to identify and select contactless electronic modules (MDL) by a terminal is provided. A module may generate a random identification number prior to a communication, and respond to a general or complementary identification request on a time slot that varies according to its identification number. A non-selected module may generate a new random identification number when it receives a complementary identification request. Thus, the time slot of a non-selected module provided in response to a complementary identification request is not statistically the same as its time slot in response to a previous identification request, and it varies according to its identification number (ID).
