A coated roller comprising
- a roller core made of metal,
- a coating on said roller core, and
- an externally inducible microtransmitter, which microtransmitter is attached at or below the surface of the roller core in such a way that the microtransmitter is not non-destructively removable, and which microtransmitter emits, when induced, a multidigit alphanumerical code of identification.
In a method of making a coated roller involving applying a coating to a roller core made of metal, the improvement comprising
- attaching an externally inducible microtransmitter at or below the surface of the core in such a way that the microtransmitter is not nondestructively removable, which microtransmitter emits, when induced, a multidigit alphanumerical code of identification.
