Patent abstract

A method for pipelined processing of access commands to a population of radio frequency identification (RFID) tags is provided. The method includes transmitting a first queued access command to a first tag in the population of RFID tags, transmitting a second queued access command to a second tag in the population of RFID tags, and transmitting a status request command to the first tag. The queued access command causes the first tag to perform an operation and upon completion of the operation, to suspend transaction processing. The second queued access command is transmitted while the first tag is performing the command operation. The status request command causes the first tag to resume normal processing.
