Abstract
For controlling access rights between a read/write device (1) and a transponder module (2) configured to exchange data via an electromagnetic field (3), the read/write device (1) obtains via the electromagnetic field (3) from the transponder module (2) a technology release code (T) which indicates a version of technology of the transponder module (2). Subsequently, the read/write device (1) sets access rights for the transponder module (2) using the technology release code (T). Setting access rights based on a technology release code (T) obtained from a transponder module (2) makes it possible to block transponder modules (2) selectively, depending on their inherent technology release, so that transponder modules (2) with a technology release that is without a security breach may remain in operation whereas transponder modules (2) with a technology release having a compromised security can be blocked from access.
