System and method for verifying RFID reads
First Claim
1. An RFID reader and imaging system for verifying an RFID read, said system comprising:
- RFID reader circuitry for performing the RFID read by receiving RFID tag data from an RFID tag;
an imaging engine having an array of image sensors for sensing an image of an object and generating image data;
a database storing a plurality of RFID codes and image data associated with each respective RFID code of the plurality of RFID codes, wherein the associated image data represents at least one image of at least one object having an RFID tag; and
a processing unit for receiving the RFID tag data from the RFID reader circuitry and the generated image data from the imaging engine, said processing unit comprising;
an RFID decoding module including programmable instructions executable on the processing unit for decoding the received RFID tag data and generating an RFID code;
a database query module including programmable instructions executable on the processing unit for accessing stored image data associated with an RFID code which matches the generated RFID code; and
a comparator module including programmable instructions executable on the processing unit for comparing the generated image data with the accessed image data for determining whether the generated image data corresponds to the generated RFID code for verifying the RFID read.

Abstract
An RFID reader and imaging system is provided having a device for imaging an object associated with a tag whose RFID code is read by an RFID reader. The imaging device generates image data associated with the imaged object. The system further includes a database storing RFID codes associated with a plurality of objects and complete or extracted image data associated with each stored RFID code. Verification software executable on at least one processor of the system is provided for verifying whether the RFID code presented to be read and processed by the RFID reader and imaging system corresponds to the imaged object. The process of verification is performed by comparing the acquired image data or other data associated with the imaged object with the stored image data or other stored data corresponding with the RFID code read. If the acquired image data or other data substantially matches the stored image data or other stored data, then the system verifies that the appropriate RFID code was read. If the acquired image data or other data does not substantially match the stored image data or other stored data, then the system verifies that the appropriate RFID code was not read, or that the system contains an error.
