Abstract
A detectable identification device (DID) comprising a communication device, a power converter device, memory, and a processor and/or read-write logic and counter logic is disclosed. The counter logic of the DID may selectively increment a counter value stored in the memory ever time the DID has been accessed by a reader. Furthermore, a method for detecting and monitoring the number of times the DID has been accessed is disclosed. This may comprise comparing a reader access count to the DID counter values to determine if unauthorized access is occurring.
