Wuhan: RFID quietly changes life

the identification system automatically collects commodity information

1 second can calculate the account

suppose you walk into a supermarket now, there will be an automatic voice to greet you immediately, it will write down your name and remind you to buy milk, because you haven't bought anything for 3 days since the last purchase. Moreover, the machine knows which brand you want to buy, how often you should buy it when the exposed shaft end protrudes between the end faces of the housing, how many family members are there in your family, etc. This sounds like a science fiction story, but in fact it is not far from our reality. On May 9, Zou bin, a research and development personnel of Wuhan Feitian Intelligent Engineering Co., Ltd., told that the radio frequency identification system (RFID) they were developing might do this in the near future

Zou bin introduced that radio frequency identification (commonly known as electronic tag) technology originated from the friend or foe identification system applied in the Second World War. It takes wireless communication technology and large-scale integrated circuit technology as the core, uses radio frequency signals and their spatial coupling and transmission characteristics to automatically identify stationary or moving targets, and efficiently obtain target information data. If it is further combined with Internet technology, It can also realize global target tracking and information sharing. This expression may be more technical, and it is difficult for people to wash clothes more clearly and cleanly. You will understand it by looking at the application of electronic labels in real life

Zou Bin said that now when you go shopping in the supermarket and take the selected goods to the cashier to pay, the cashier will scan the bar code on the goods with a scanning device, and the type and price of the goods will be reflected through the bar code. This is familiar to everyone. However, there are defects in the way bar codes are used to identify goods. For example, the same kind of toothpaste produced this year and last year reflects the same information from the bar codes. The same is true of similar foods. This means that if we buy expired goods, they cannot be identified by barcode

is there a better technology to replace bar code? The answer is: Yes. That is electronic labels. Compared with bar code, the information reflected by electronic labels will be richer, more comprehensive and more personalized. It attaches to the goods through micro chips, and reflects the information and price of the goods, including the production month, production line, manufacturer information, etc. through such a system, merchants can automatically identify expired goods and understand the inventory of goods in real time, such as goods that are fast-moving can be replenished in time, expired goods can be removed from the shelves in time, etc. This series of printers is simpler than needle installation

for ordinary customers, the standard reference conditions are also called standard experimental conditions. In other words, the biggest advantage of electronic labels is convenience. We know that when we pay for shopping now, the cashier will scan the goods you choose one by one. When there are many people shopping in the supermarket, you may wait in line for a long time for payment. But in the future, with electronic tags, customers don't need to queue up to pay, and they don't need to scan all the goods one by one. As long as customers push their shopping carts through the RFID system to identify the safety door, in less than 1 second, the system will automatically collect all the goods you buy, including the price of each item, and automatically generate your bill. You don't even have to take the goods in the shopping cart to the checkout counter. All you have to do is swipe your card and leave

zoubin told that at present, it will take time for electronic labels to replace bar codes, but their technology has been applied in Wuhan Library

how convenient is it for borrowers to use the electronic tag system in the library? Zou Bin said that in the past, the procedure for readers to borrow books was: first find the books that need to be borrowed from the bookshelf, and then go to the service desk to go through the borrowing procedures. However, after adopting the electronic tag system, the borrower does not need to go to the administrator to handle the borrowing procedures at all, and the library can even be unattended, because the chip is attached to each book, and the reader's library card also carries an electronic tag. After selecting the book, as long as the password is entered in the autonomous borrowing and returning system, the borrower can smoothly pass through the security door, just like withdrawing money with an ATM
