20100253481 | Method and system for miniature passive RFID tags and readers - This invention makes possible small size, long range, reliable, low-power, low-cost RFIDs fulfilling the needs of the industry and the roadmap set for RFID, as by Walmart and the DoD. Tag energization and data communication take place by independent means. The invention employs low-power communication means, such as ultra wideband (UWB), for transfer of data between Tag and Reader, and relatively high power narrowband means to remotely energize the Tag. Said means of powering and communication mechanisms, further, are independent of the underlying process, or technology, of implementation of the Microchip on the Tag, as well as from the transceiver technology aboard the Reader. As such, they provide an ideal method and system by which to power and communicate with RFIDs, through cycles of evolution and changes in physical implementation technology. | 10-07-2010 |
