Un telephone portable qui lit les codes bares et donne toutes les infos sur le produit scané.

Ce prototype de tel portable developpé par Ubiquitous ID Center comporte un lecteur de codes bares et de tag magnetiques qui permet d'identifier instantanément le produit en question et ses proriétés/caracteristiques.

Un utilisateur pourait ainsi trouver immediatement grace a son portable des info telles que l'origine exacte du produit ... ou bien son prix de vente dans d'autres magasins.

Edit: A terme il serait eventuellement possible de payer l'objet directement par le portable (on peut deja payer bcp de services par virement bancaire directement sur le portable), on passerait alors a la caisse uniquement pour demagnetiser les tags magnetiques antivol (s'il y en a) et emballer l'objet si necessaire.

Ubiquitous ID Center Incorporates Wireless Tag Reader/Writer in PHS

December 10, 2003 (TOKYO) --
The Ubiquitous ID Center has made a prototype Personal Handyphone System (PHS) terminal, dubbed "UC Phone," that incorporates a wireless tag reader/writer and a barcode reader.


'UC Phone' by Ubiquitous ID Center. It incorporates a wireless tag reader/writer and a barcode reader

UC Phone reads "ucodes," identification numbers determined by the Center, from wireless tags or barcodes. It can also perform address resolution of ucodes via a PHS network.

From the scanned ucode, the address resolution process gets the IP address of a server on the network that stores information relating to the article to which the wireless tag or barcode is attached. This allows the user to retrieve information about the scanned ucode. Having accessed the URL at which the information is located, the user can browse or download the information. For example, from the ucode of a barcode attached to lemons, the user can find out the producing area, cultivation history, distribution routes, and other information.

The reason for supporting barcodes as well as wireless tags is that the company believes barcodes will still serve a purpose even if wireless tags become widely used in the near future.

"I don't imagine that wireless tags will be used on ultra-cheap articles. Barcodes are so much cheaper than wireless tags. I expect tags and barcodes will be used differently, as befits the type of product," said Ken Sakamura, a professor at the University of Tokyo and representative of the Ubiquitous ID Center.

"PHS base stations are getting less expensive to build. Some have cost less than one million yen. The cost outlay is now within reach of small and mid-size companies looking to deploy PHS. Incorporating a Ubiquitous ID reader/writer in a PHS terminal that can be used both outdoors and indoors means greater opportunity for utilizing handheld mobility. And if you consider the lower call charges and base station costs, PHS at present is the more practical option compared with third-generation mobile phones," Sakamura explained.

The built-in reader/writer module is made by Toppan Printing Co, Ltd. It communicates in the 2.45GHz band over a distance of about 5cm with an output of less than 10mW. The module measures 50mm x 40mm x 10mm, and consists of two boards one on top of the other. The printed circuit board contains the communication circuitry, and the other board serves as the antenna. The barcode reader is capable of scanning one-dimensional barcodes compliant with EAN128, which allows up to 128 bits of information to be encoded.

The Ubiquitous ID Center has licensed two companies, Sato Corp and Toppan Printing, to act as issuing agents for ucode-based barcodes. The Center categorizes barcodes and wireless tags into seven classes differentiated by the enabling technology. Barcodes belong to Class 0. The two licensed companies will manage the ucodes issued by the Ubiquitous ID Center, and will be able to assign them to their customers.

The Ubiquitous ID Center and its two agents will begin issuing ucodes for barcodes in 2004. No details about the service have been decided, but ucode issue will cost about the same as the Japanese Article Number (JAN) codes currently in use, the company said.
