Abstract
The invention relates to a device for monitoring physical objects that comprises one or more short-range remote readers (13), memory elements (5) to be attached to physical objects, and a controller (15) adapted for executing a reading function capable of interaction with the one or more remote readers in order to acquire data contained in adjacent memory elements, and for executing an integrity validation function capable of distinguishing, from the acquired data, individual identifiers particular to each of the memory elements as well as group description data stored in at least some of said memory elements, and of checking the sufficiency of group description data while checking the compliance of individual identifiers with corresponding group description data.
