Abstract

Official abstract text for this publication.

A multi-mode RFID tag includes a power generating and signal detection module, a baseband processing module, a transmit section, a configurable coupling circuit, and an antenna section. In near field mode, the configurable coupling circuit is operable to couple the transmit section to a coil or inductor in the configurable coupling circuit to transmit an outbound transmit signal using electromagnetic or inductive coupling to an RFID reader. In far field mode, the configurable coupling circuit is operable to couple the transmit section to the antenna section, and the multi-mode RFID tag then utilizes a back-scattering RF technology to transmit the outbound transmit signal to RFID readers.

First claim

Opening claim text (preview).

The invention claimed is: 1. A radio frequency identification (RFID) device, comprises: at least one processing module operable to generate an outbound transmit signal in a near field mode and a far field mode, wherein the at least one processing module is configured to encode the outbound transmit signal using a first protocol when in the near field mode and encode the outbound signal using a second protocol when in the far field mode. 2. The RFID device of…
