Abstract
A method of associating radio-frequency identification (RFID) tags with a region, location, or container is provided. The method can comprise, among other steps, transmitting an interrogation signal with an RFID reader corresponding to a read zone of a first size, receiving a response from at least one of the plurality of RFID tags in the region as a new tag, recording an indicator of the response of the at least one of the plurality of RFID tags, thereby designating it as a recorded tag, increasing the read zone of the RFID reader until no new tags are detected, and associating of each of the recorded tags with the region.
