The invention relates to a device for monitoring physical objects that comprises one or more short-range remote readers, memory elements to be attached to physical objects, and a controller 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.

Device and method for checking the integrity of physical objects

The invention relates to a device for monitoring physical objects that comprises one or more short-range remote readers (), memory elements () to be attached to physical objects, and a controller () 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.

The inventive information distributing system (), in particular for railway stations or airports, comprises a control unit () delivering information items selected according to a first key value to a main distributor (), a short-range communications relay () for establishing connections with mobile terminals (). Said control unit comprises a relay interface and a control module carrying out a function of general distribution to the distributor, an inventory function for interacting with the terminals by storing state data received therefrom and by setting a second key value according to a state data sub-group and a particular distribution function for transmitting the information items selected according to the second key value to the terminals having the second sub-group state data.
