In January 2008 for Xi'an Jiaotong University Intelligence Laboratory provides ultra-high frequency reader and labels, Xi'an Jiaotong University is to use RFID technology to develop a set of RFID intelligent laboratories, the advantages of radio frequency technology for the laboratory Provides a perfect solution.
And the traditional bar code identification technology, RFID has the following advantages:
1. Quick scan
Bar code can only be a bar-code scanning; RFID reader can be read at the same time to identify a number of RFID tags.
2. Small size, the shape of diversification
In the RFID reader is not affected by the shape and size restrictions, in order not to read with accuracy and fixed-size paper and printing quality. In addition, RFID tags can be to small and diverse patterns of development, to apply to different products.
3. Durability and anti-pollution
The traditional bar code is a carrier of paper, so vulnerable to pollution, but RFID for water, oil and chemical substances, such as a strong resistance. In addition, due to the bar code is attached to the outer plastic bags or cardboard boxes, so are particularly vulnerable to impairment; RFID label is the existence of the data chip, it can be free from fouling.
4. Reusable
Today's bar code printing will not be able to go after the change, RFID tags can be repeated to add, modify, delete
RFID tags inside the store data to help update the information.
5. Penetrating and barrier-free reading
In the coverage of the case, RFID can penetrate paper, wood and plastic, and other non-metallic or non-transparent material, penetrating and able to carry out communications. The bar code scanners at close range and there is no need to stop the objects, can read bar codes.
6. Data memory capacity
One-dimensional bar code is the capacity of the 50Bytes, two-dimensional bar code can store the maximum capacity of 2-3000 characters, RFID is the largest capacity of a few MegaBytes. With the memory of the development of the carrier, data capacity is also growing. Future articles carried by the amount of data needed to be more and more, the label can expand the capacity of a corresponding increase in demand.
7. Security
RFID is due to carry electronic information, the data are available through a password-protected so that content can not easily be altered and forged.
In recent years, RFID has distance by their reading, high storage capacity, and other characteristics of a great deal of attention. It not only helps a substantial increase in cargo business, information management efficiency, but also allows the sale Internet companies and manufacturing enterprises in order to receive more accurate feedback, information needs to control and optimize the entire supply chain.
