ABSTRACT:
RFID tags are identified. In one embodiment, RFID tags may be chosen to respond to an interrogator in accordance with an arbitration scheme. According to one arbitration scheme, each chosen tag may randomly pick a slot value. The interrogator may indicate that the number of slot values is to be adjusted. Each chosen tag may respond to the interrogator with a random number.
