Abstract

Transponder (104), comprising a storage unit (106) having stored a number of different applications, a processing unit (108) which, on request of a reader (102), is adapted to generate a response interpretable using an encryption scheme known by both the transponder (104) and the reader (102) so that the reader (102) is capable of determining whether an application is supported by the transponder (104) by analyzing the response using the encryption scheme, and a transmission unit (110) adapted to send the response to said reader (102).
