Abstract
An RFID system for verifying whether an object that has been transported to a first destination has reached its intended destination. An RFID transceiver tag is mounted on the object. The intended destination is stored in a memory within the tag. An interrogator at the first destination sends an RF interrogation signal, to which the tag responds by transmitting an RF signal containing its intended destination. The interrogator compares whether the intended destination transmitted by the tag is the same as the first destination and, if not, the interrogator signals that the object should not be delivered to the destination.
