Abstract: A method of adding TTO functionality to an RTF RFID air protocol, such as ISO/IEC 18000-63 and EPC C1G2 protocol, Chinese GB/T 29768-2013. The starting wait state is changed after power-up of the RTF protocol to a TTO state where the tag automatically transmits an ID or an ID plus additional data at intervals to a reader while still waiting for possible RTF commands. A new command is added that enables the reader to obtain a handle from the tag directly from the TTO state to access the tag in an identical manner to the RTF access. The TTO functionality is as defined by the ISO/IEC 1800-64 protocol or IP-X protocol.
