Abstract
A method provides a tamper loop status of a radio-frequency transponder to a reader. The transponder communicates with the reader at a first frequency according to a first communication protocol. The transponder includes a first non-volatile memory for storing a first set of data of the first communication protocol. The first memory includes a user memory having two portions and each portion includes a data item specific to a status of the tamper loop. The method is performed by the transponder after receiving a request according to the first protocol to read the user memory and includes generating a logical view of the user memory, the logical view including only one of the two portions that is selected according to a value of a binary parameter representative of a status of the tamper loop. The method also includes providing the logical view to the reader via the first protocol.
