Abstract
An inventory system configured for detecting and counting potentially retained surgical items within a body of a patient includes a signal generator which generates an energizing signal for a first RFID tag affixed to a secure package or the second RFID tag affixed to a surgical item, an antenna operably coupled to the signal generator, a processor, and a memory. The antenna is configured to receive at least one of the first return signal transmitted by at least one of the first RFID tag or the second return signal transmitted by the second RFID tag. The memory includes instructions which when executed by the processor cause the system to energize the first RFID tag, receive from the antenna the first return signal including a first unique identifier, and generate a key based on the first unique identifier and a master private key stored on the memory.
