Storage unit comprising a main data carrier and a contactless chip

A storage unit comprising a main data carrier and a contactless chip associated with said main data carrier, said contactless chip comprising:

• receiving means for receiving a powering signal sent by a portable radio-communication device,
• processing means, memory means, and transmitting means for executing at least one of the following actions:
• a) returning chip data stored in said memory means and descriptive of said storage unit upon reception of a powering signal;
• b) if said powering signal carries device data relating to a storage unit wanted notice, checking whether the storage unit is the wanted storage unit and transmitting a warning to said portable radio-communication device if said storage unit is the wanted storage unit;
• c) if said powering signal carries device data relating to a request for storing specific data in said chip, storing said specific data in said memory means,
• d) if said powering signal carries device data relating to a request for retrieving specific data stored in said memory means, transmitting said specific data.

A method of manufacturing a storage unit, said method comprising:

• providing main data on a main data carrier,
• providing at least program instructions on a contactless chip that comprises receiving means for receiving a powering signal carrying data, processing means, memory means, and transmitting means for transmitting a signal carrying data,
• embedding said contactless chip in a caddy,
• packaging said main data carrier in said caddy,
• said program instructions being intended for the execution of at least one of the following actions when executed by said processing means:
• a) upon reception of a powering signal that carries a request for storing specific data in said chip, storing said specific data in said memory means,
• b) upon reception of a powering signal that carries a request for retrieving specific data stored in said memory means, returning a signal carrying said specific data.

A method of manufacturing a storage unit, said method comprising:

• providing main data on a main data carrier,
• providing at least part of said main data, that is descriptive of said storage unit, and program instructions on a contactless chip that comprises receiving means for receiving a powering signal, processing means, memory means, and transmitting means for transmitting a signal carrying data,
• embedding said contactless chip in a caddy
• packaging said main data carrier in said caddy,
• said program instructions being intended for the execution of at least one of the following actions when executed by said processing means:
• a) upon reception of a powering signal, returning data stored in said memory means and descriptive of said storage unit,
• b) upon reception of a powering signal that carries a wanted notice relating to a wanted storage unit, checking whether the storage unit is the wanted storage unit and, in such a case, transmitting a warning.
