ABSTRACT:
Interfacing is provided, to a utility of an RFID reader. The utility causes the RFID reader to instruct tags to reply using changed reply timing. The interfacing enables an agent to control the utility, for installing it, configuring it, enabling it, disabling it, or operating it. In a number of embodiments, the tag timing change is achieved by causing a custom timing command to be transmitted to a tag. In some embodiments, the changed reply timing alters the delay before a tag backscatters a reply.
