Abstract
A reading device for identifying a tag or an object adapted to be identified is disclosed. The reading device includes a first reading element for reading a first set of identification features located in the tag or the object adapted to be identified, wherein the first reading element is a magneto-optical reading element; and a second reading element for reading 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.
