  • System and method for communicating with multiple transponders
    Patent number: 6535109
    Abstract: The object of the invention is a system and method for identifying and communicating with a plurality of transponders which are at the same time in the same interrogation field. The system is based on an interrogator which sends interrogation bursts in a periodical manner, and transponders which send the response back with a random delay related to the end-of-burst event. The system is primarily suitable for passive (no additional power supply) transponders, but can also be used for active transponders.
