Method and apparatus to facilitate setting RFID tags to a particular read state

摘要

A wireless transmitter is configured to transmit compatibly to RFID tags and a control circuit operably couples to that wireless transmitter and is configured to use the wireless transmitter to transmit to those RFID tags a message to cause the RFID tags to have a particular read state without also soliciting a corresponding response from any of those RFID tags. For example, this can comprise causing RFID tags having a B inventory state to switch to an A inventory state (while permitting RFID tags already having an A inventory state to so remain).

主权项

1. An apparatus for use with radio-frequency identification (RFID) tags having selectively changeable read states, the apparatus comprising:
a wireless transmitter configured to transmit compatibly to the RFID tags; a control circuit operably coupled to the wireless transmitter and configured to use the wireless transmitter to transmit to the RFID tags a message to cause the RFID tags to have a particular read state without soliciting a response from any RFID tag, wherein the particular read state specifies, at least in part, whether to respond to a read request.
