摘要:
A transponder for wirelessly receiving external data and for monitoring access to application data, the transponder including: a data storage storing application data; a data storage control region; and a data storage access controller configured to store, in the data storage control region, data indicative of an access to the application data stored in the data storage, when the application data was accessed based on the external data. Further, a method and a reader for monitoring access to application data stored in a transponder are described.
摘要:
A device for use in electronic article surveillance EAS is disclosed which comprises a resonant circuit, typically designed for 8.2 MHz operation, in addition to a transponder, such as RFID, for non-contact communication with a communication station. The RFID transponder can provide a signal to detune the resonant circuit to disable the EAS and optionally another signal to tune or retune the resonant circuit to enable or re-enable the EAS. The detuning and tuning or retuning may preferably be achieved using phase change memory material, configured as a programmable switch having two states with different resistances.
