Abstract

A reader and method to allow verification or access to an RFID component of a device using analog optical properties of the RFID device. In the method, a reader analyzes optical properties of the device, obtains information on these properties from the reader or from data on the device. These optical analog properties are required to be verified prior to access to the RFID data from the RFID component.

Claims

1. A method comprising:

providing an RFID device;

reading an optical signal from a location on said device generate analog optical data; and

using said analog optical data to access RFID data.

2. The method of claim 1, wherein said optical signal is from a specific targeted location on said RFID device.

3. The method of claim 1, wherein said optical signal is from a marked target.

4. The method of claim 1, wherein said optical signal is from an optical media on said RFID device.

5. An optical reader for analyzing an RFID device, comprising:

an optical analytical component configured to obtain analog optical data from a target;

an RFID reader able to interrogate an RFID component of a target; and

a processor configured to access RFID data using said analog optical data.
