1. An electronic tag which includes:
- an RTF protocol engine and a TTF or TTO protocol engine, respectively to operate the tag in RTF protocol mode and in TTF or TTO protocol mode;
a switch operable to switch the tag between an RTF protocol mode and a TTF or TTO protocol mode;
a detector including an RTF protocol detector and a TTF or TTO protocol detector, respectively operable to detect automatically whether a conventional reader or interrogator is broadcasting in an RTF protocol mode or a TTF or TTO protocol mode, the switch being operable to switch the tag automatically to the detected mode.

6. A method of operating an electronic tag, the method including:
-
receiving a signal from a conventional reader or interrogator; detecting by means of the tag an RTF protocol preamble or a TTF or TTO protocol header in the signal, thereby to detect whether a reader or interrogator is operating in an RTF protocol mode or in a TTF or TTO protocol mode; and switching the tag automatically to that mode.
