摘要： A transponder (1) comprises at least one memory (MEM1, MEM2) for storing encrypted information (E_k(EPC, PI)) that has been encrypted by use of a key (k) and for storing the key (k) associated with the encrypted information (E_k(EPC, PI)). The transponder (1) is adapted to send the key (k) slower response than the encrypted information (E_k(EPC, PI)) in response to queries of a reading device (2), which is preferably done by delaying the transmission of the key (k) or by limiting the response rate at which the key (k) is transmitted. In particular the invention is related to RFID systems.

摘要： A radio frequency identification, RHD, device (116) for use at an article (114) is described that communicates information with a washing machine (100). The RFID device (116) comprises RFID circuitry (118), an antenna (120) connected to the RFID circuitry (118), as well as switching means (122) connected to any of the RFID circuitry (118) and the antenna (120) and configured to react to contact with a fluid (108) in the washing machine (100) by switching the RFID circuitry (118) from a first mode of operation to a second mode of operation. The two modes of operation comprise at least a respective first and second ability to communicate with the washing machine (100).
