Japan's pan-center experiment wireless label and two-dimensional barcode in the ID center and uses the Japanese BP network on the collaboration of Sanfu Japan Bridge Board, Japan, has started wireless label in the mall in the ID center. Senior melons such as melons sold in the store food counter, beef and pork are experimental objects. This shopping mall experiment started 2 weeks since February 2, 2005. In addition to the experiment, Japan, Broiler, Today, Japan Sun Fruit, Jinggang County Greenhouse Rural Cooperatives Jing South Branch, Tokyo Qinggui, Second, Japan Meat-Companion and Hengqi Tech Park (Telecom Research Park, YRP). In February 2004, the ID Center was jointly Japanese Beijing, Ye Yushan Rural Cooperatives, Hengqi He Ye Yushan Rural Cooperative, Hengqi Heiqi, Hengqi Tech Park, jointly implemented a 1-month mall experiment. This shopping mall experiment has a great difference between the experiments conducted in Beijing last year, which is the use of wireless labels and two-dimensional barcodes. The product has a transparent box with a wireless label, which is equipped with a card with a two-dimensional barcode and a normal barcode. When you need to check the production process of the product, the portable information terminal - "is w so on the communication terminal (Ubiquitous Communicator). Alternatively, a card with a two-dimensional bar code is placed in the store in the mall, which can display information such as the production process. Using wireless tags from the production site to the shopping malls, use two-dimensional barcodes after the goods are available, see the production process -, because the wireless tag and two-dimensional barcode are used, for more consumers, goods Trackability is more realistic. Because many mobile phones have functions that read the two-dimensional barcode, it is gradually become a function of a Puchong. If you use your mobile phone, you can easily review product information such as production process even at home. The prerequisites identified by the verification experiment last year were from the production site, to the mall, and then to consumers all managed by wireless tags. Therefore, the participating personnel participating in the verification experiment will be collected and rented it to them in the communication terminal. For this method, if consumers cannot easily get terminals with wireless tag reads, it is difficult to use in actual use. At the same time, use wireless tags and two-dimensional barcodes, there is another advantage. That is to solve the privacy problem that has become a problem in the United States. If the item is sold in the case of a wireless label, then in the way of shopping home, the product information may be read from the third party using the wireless tag card reader. In other words, when consumers don't know, I bought something such as personal information will leak. However, if the two-dimensional barcode is used as this time, the possibility of personal information leakage will be reduced.
