Reading device for identifying a tag or an object adapted to be identified, related methods and systems

A reading device for identifying a tag or an object adapted to be identified, said reading device comprising:

• a reading element for reading both magnetic features and optical features located in the tag or the object adapted to be identified, wherein the reading element comprises at least one optical processing unit and at least one magneto-optical substrate;
• and wherein the reading element comprises at least one opening for a direct optical reading of optical features and/or alignment marks on the tag or the object adapted to be identified.

A method of identifying a tag or an object adapted to be identified, the method comprising reading both magnetic features and optical features with a reading element, wherein the reading element comprises at least one optical processing unit and at least one magneto-optical substrate;

• and wherein the reading element comprises at least one opening for a direct optical reading of said optical features on the tag or the object adapted to be identified.

A method of identifying a tag or an object adapted to be identified, the method comprising:

• generating a first signal from a magneto-optical reading of a first set of identification features located in the tag or object adapted to be identified only, wherein a first set of identification features comprises a disordered arrangement of magnetic or magnetisable particles included in an identification layer of the tag or object;
• wherein the first signal generated from reading the first set of identification features as such is used to derive a first signature for identifying the tag or object.

A method of identifying a tag or an object adapted to be identified, the method comprising:

• generating a first signal from a magneto-optical reading of a first set of identification features located in the tag or the object adapted to be identified, generating a second signal from reading a second set of identification features located in the tag or the object adapted to be identified;
• wherein the first signal generated from reading the first set of identification features and the 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 the object.
