The security device has a first portion disposable on a first side of a separation boundary of a separable object, and a second portion disposable on a second side of the separation boundary. The security device further includes a first Radio Frequency Identification (RFID) circuit configured to provide a first return signal. The data device includes a microprocessor and system memory, an RFID reader 210 and a radio antenna 208. The data device is configured to transmit and receive radio frequency signals with the first RFID circuit, and to recognize the first return signal as indicating an untampered condition of the separable object.SELECTED DRAWING: Figure 2 |
