Abstract
Protocol-specified RFID tag inventorying can be modified to streamline information exchange. For example, RFID tags may be able to respond to certain RFID reader commands with additional or other information instead of only a pseudorandom number or a certain tag identifier, or may not even respond at all. Such other information may include all or portions of other tag identifiers, or information associated with tag identifiers, such as error-checking codes or protocol control bits. Tags may also choose data stored in tag memory with location of the data known only to the tag, compare to a mask received in an inventorying command and decide to participate or not in an inventory round based on a comparison result.
