Abstract: A method for transmitting information from a first security module to a second security module involves a system comprising the first and the second security modules. An anti-collision phase comprises a sequence of anti-collision queries, and a communication phase follows the anti-collision phase. The first security module transmits the information to be transmitted to the second security module in the anti-collision phase by sending responses of the first security module to the sequence of anti-collision queries, with the information to be transmitted being encoded in the responses of the first security module. The second security module decodes the information to be transmitted from the sequence of the received anti-collision queries. Furthermore, the invention discloses a first and a second security module, in particular for transmitting information.
