A READING DEVICE ABLE TO IDENTIFY A TAG OR AN OBJECT ADAPTED TO BE IDENTIFIED, RELATED METHODS AND SYSTEMS

摘要

A reading device for identifying a tag or an object adapted to be identified is disclosed. The reading device includes a reading element for reading a first set of identification features located in the tag or the object adapted to be identified, wherein the reading element is a magneto-optical reading element. The reading element also reads a second set of identification features located in the tag or the object adapted to be identified; wherein the reading device is configured such that a first signal generated from reading the first set of identification features and a second signal generated from reading the second set of identification features are independently used to derive a first signature and a second signature for identifying the tag or object.
