- This portable device which can be directly worn by the user thus allows the latter to follow in real time the state of the stock and therefore the self-triggering of the various labels, without however being obliged to periodically check the shelves to check if a label has been triggered.
- the transmission circuit 4 and the antenna 3 of each of the labels will be suitable for transmitting messages with a range in free field of 50 to 800 m.
- the external device can be arranged outside the stocks.
- the microcomputer 13 of the external device can also include a table. allocation which includes in a third field ( Figure 5) data relating to the exact location of the item in the stock.
- the user searches through the database relating to the different identification codes of all the labels, for an identification code of a available label, i.e. a label which is not yet assigned to any of the articles and assigns this identification code in the first field of the allocation table. Then, the user enters the microcomputer by any means of acquisition such as a keyboard, the data relating to the article in question so that the microcomputer affects these data (task to be carried out, serial number of the article and / or type of article, etc.) in the second field in correspondence with the identification code of the label. And finally, the user enters in a third field of the allocation table the data relating to the exact location in which the article in question will be stored.
