Bon, comme je visite les nouveautés hitachi, en voici une autre tout aussi impressionante que les nouveaux écrans.
C'est une micro-puce qui peut être intégrée dans du papier, par exemple billets de banque qui contient un ID spécifique.
Voici la puce comparée à des grains de riz
Avec l'article associé (en anglais) source http://www.rfidjournal.com/article/articleview/556/1/1/
| Citation: | Sept. 4, 2003 - Japanese semiconductor giant Hitachi has unveiled a prototype of its tiny RFID µ-chip, or mu-chip, which features an antenna built onto the microchip. The new tag is so small that the company believes it can be embedded in paper and used to authenticate banknotes and valuable paper documents.
Chips dwarfed by grains of rice.
Hitachi says the tiny tag, which holds a 128-bit serial number, can be used in stock and bond certificates; tickets, gift certificates and coupons; and identification documents, such as passports. The mu-chip can prevent counterfeiting because it provides a traceable number and can't be duplicated easily.
Reports that the mu-chip will be used in Japanese yen banknotes are untrue, according to Kantaro Tanii, a Hitachi spokesman. But Hitachi does anticipate that the mu-chip will be used to prevent counterfeiting of banknotes. "We have no government or bank contracts as yet, but it's a market we expect to grow," Tanii says.
The prototype mu-chip is 0.4 mm x 0.4 mm, the same size as the original version, which required an antenna to be attached. The tags should be more durable because there is no antenna to break off. And Hitachi says the new mu-chip should be less expensive than the existing mu-chip, because the company has eliminated the need to attach an antenna. The new chip is expected to cost half of the 50 to 70 yen each (43 to 60 U.S. cents) the current chip costs. It will be commercially available next year.
The new design uses a process called bump metalization to create the electrical contacts of an integrated circuit on the chip rather than etching the antenna onto the chip during the CMOS process. Hitachi says that, unlike etching, bump metalization eliminates the need for any specialized equipment to manufacture the chips. "We don’t need to add any additional investment to the manufacturing process for this chip," says Tanii.
The one drawback of putting the antenna right on the tiny chip is that it shortens the read range. The new mu-chip can be read from just 1 mm (.04 inch). Even so, Hitachi is convinced that the new mu-chip makes RFID tracking possible in extremely minute and precise applications that had been impractical until now. The company already has plans to embed the new mu-chip in entrance tickets for Expo 2005 Aichi Japan, which opens on March 25, 2005.
Another high-potential application is agricultural products, where the chips can help ensure the safety of food by providing traceability of ingredients, says Tanii. The company also believes its new tag is suited to more traditional retail and supply chain applications.
Hitachi’s first mu-chip, with the external antenna, was announced in July 2001. The company says the new tag is fully compatible with all systems that use Hitachi’s current mu-chip technology.

Et la page de chez hitachi : http://www.hitachi.co.jp/Prod/mu-chip/
Moi je vois déjà venir d'autres applications, du style Big Brother. A lire cet article avec comme titre RFID tags: Big Brother in small packages (en anglais) ici http://news.com.com/2010-1069-980325.html
petit édit
En rapport avec le Japon, on avait parlé sur un autre fil des nouveaux détecteurs dans les écoles japonaises pour savoir si l'enfant est arrivé, parti de l'école. Il s'agissait dans ce cas aussi de RFID tag.
J'attends le jour ou ils vont installer un système similaire dans les entreprises, peut-être même sans le signaler aux employés. N'oublions pas que vu la taille de ces puces, on peut les camoufler dans presque n'importe quoi
Et aussi, la nouvelle puce de hitachi est la plus petite 0.4 mm et la première à 128kbit, et ils résolvent aussi le problème de l'antenne.

Toujours à propos de ces RFID, je suis allé le week-end passé chez Virgin pour écouter des CD et là j'ai remarqué les nouvelles bornes sécurités, bien différentes de celles précédemment utilisées. En regardant bien un CD, mais ne serait-ce pas les nouvelles puces RFID qui font leur apparition.
Cela ne me surprend pas trop, mais ce qui me surprend c'est que je n'ai vu noté nulle part dans le magasin le changement de système, pourtant j'ai lu l'année passée une recommandation du gouvernement :
| Citation: | June 08, 2004
Japanese RFID Privacy Guideline Released
Japanese Ministry of Public Management, Home Affairs, Posts and Telecommunications (Soumu-Sho) and Ministory of Economy, Trade and Industry (Keizai-Sahgo Sho aka METI) jointly released an RFID Privacy Guideline today.
The ministries made their own guidelines in March. Since then, they have been discussing to integrate the two guidelines.
The guideline articulates the following points:
(1) Indication that RFID tags exist
(2) Consumers right of choice regarding reading tags
(3) Sharing information about social benefits of RFID, etc.
(4) Issues on linking information on tags and databases that store privacy information.
(5) Restrictions of information gathering and uses when private information is stored on tags
(6) Assuring accuracy of information when private information is stored on tags
(7) Information administrators
( Information sharing and explanation for consumers
In relation to (2), the guideline says that it is necessary to show consumers how to prevent their tags from being read. It also introduces a few sample methods like "covering tags with aluminum foil," "deleting information on tags using an electro-magnetic method," and "physically removing tags."

Donc le point (1) ou il recommande de signaler la présence de ces puces. Ce qu'on va s'amuser avec ses nouvelles puces, quand on sait que le japon va introduire pour 2006 les nouveaux passeport avec ces puces, les américains pour bientôt aussi :
| Citation: | | On Monday, Japanese government decided to introduce RFID-chippepd passports by March 2006. RFID chips will be used to store and communicate head-shot photos of passport holders. Yomiuri Shinbun |
Je me demande vraiment, un petit lecteur de RFID avec amplificateur dans la poche, et hop on peut lire les information des passeports des gens se trouvant autour de nous. Si on a aussi le petit soft, hop on efface les données de la puce. Je pense bien que ce ne sera pas si facile mais je ne pense pas que ce soit si difficile.
Pour ces passeports, les tests commencent le mois prochain à narita :
| Citation: | Narita Airport in Japan (which is actually where I am flying into very soon) will start a pilot test of RFID biometric cards this February. If you are a milage club memeber of All Nippon Airways or Japan Air Line, you can apply for a biometric RFID card that can make the check-in process of your next international air travel extremely efficient. The government and the airport collaborate in this pilot test project. Currently, travelers are recommended to arrive at the airport 2 hours before the departure of an international flight, however, they say, if you get a biometric RFID card, you can arrive 30 minutes before the departure instead of 2 hours. RFID readers will be available at some check-in counters, security check points, and departure control areas so that card holders can show their cards to the machines rather than human officers.
The pilot test will last for about 2 months until the end of March. |
Et pour finir, pour les gens vivant au Japon, je pense que tout le monde connait le système de payement Edy, mais est-ce que vous savez que dans ce cas il s'agit aussi de RFID, et pourquoi ce système et de plus en plus apprécié par les commercants, petit exemple chez Club Sega :
| Citation: | Club SEGA Osaki in Shinagawa, Tokyo started accepting RFID payments (i.e., payments by using Edy cards and wallet phones) some time ago and the company is loving RFID payments.
Recently, they put out a notice in the store, which says " Please use cards because we now only accepts digital money for playing games." They used to accept both coins and digital money, but not anymore. Now, coin slots of all arcade game machines are sealed with a sticker that says "Edy Only".
Why does the compnay like RFID payments so much? It's because the company now have all records about which games which customer played, how much a customer spent in the past, which other games a customer who played a certain game played, etc.
Keiichi Ito, the store's manager, says that most customers accepted the mandatory use of RFID payments. Earlier, the store's staff explained to each customer about RFID payments right after customers entered the store, however, "it negatively affected customers' motivation to play games." So, the store's new strategy is to explain about RFID payments when a customer sits in front of a game machine (i.e., just before he starts playing the game. )
Also, RFID payments freed the store's staff from the labor of collecting coins from each arcade game machine. Now the staff have more time to interact with customers.
