Abstract
For controlling access rights between a read/write device () and a transponder module () configured to exchange data via an electromagnetic field (), the read/write device () obtains via the electromagnetic field () from the transponder module () a technology release code (T) which indicates a version of technology of the transponder module (). Subsequently, the read/write device () sets access rights for the transponder module () using the technology release code (T). Setting access rights based on a technology release code (T) obtained from a transponder module () makes it possible to block transponder modules () selectively, depending on their inherent technology release, so that transponder modules () with a technology release that is without a security breach may remain in operation whereas transponder modules () with a technology release having a compromised security can be blocked from access.
