RFID tags replying using changed reply timing
摘要:
RFID tags and chips for RFID tags are capable of replying using changed reply timing. In a number of embodiments, this timing change is achieved when a tag receives a custom timing command from an RFID reader. In some embodiments, the changed reply timing affects an amount of delay before a tag backscatters a reply.
