摘要:
Obscured radio frequency identification (RFID) tags are indirectly read by an RFID reader. Other tags operate to relay the information associated with the obscured tags from one tag to another, until the associated information is ultimately received by the RFID reader from a tag in direct communication with the RFID reader. The tags may be adapted to store the received information associated with the obscured tags and then to encode this associated information and resident information in return signal(s) transmitted to the RFID reader and/or to other tag(s). The RFID reader is adapted to decode the received return signals to obtain the information encoded therein, and to process the decoded information to identify irrelevant tags and obscured tags.
