Tag "and" radio frequency identification "is going on here?

RFID is radio technology and its application in the field of automatic recognition, its English-language for Radio Frequency Identification, RFID for short. It consists of two parts: the tag (name Tag) and the reader (the English name for the Reader). Because it uses radio waves to transmit identifying information, so no space limit, faster goods tracking, exchange of information, classification, statistical analysis, and so on.

Automatic identification technology can be divided into optical technology and wireless technology, optical technology in barcode and camera are widely used in people's daily lives. Bar code technology is relatively cheap, in supermarkets and other retail sectors have been widely used, but the information cannot be changed, storage capacity is relatively small.

Radio frequency identification is a two-way communication by wireless means, its greatest strength lies in non-contact, you can implement bulk reading and remote reading to identify rapidly moving objects, compared with the commonly used barcode system, such a system can greatly simplify inventory control of product, easy to meet the increasing information flow and of increasing the speed of information processing needs.

RFID tag supports two kinds of bands: HF and UHF. Their advantage lies in: HF RFID chip can record large amounts of data, so products can be in the added value chain from production to processing to track all the important stages of, and interpretation of large quantities, thus saving time, while UHF read/write stable, long reading distance, also applies to identification of metal goods, thus enabling optimization of logistics processes. UHF opens up new space for tracking/tracking applications.

In today's rapid development of the logistics industry, radio frequency technology with its unique advantages, overcoming the need optical barcode recognition Visual, short distance recognition, information cannot be changed and so on shortcomings, automatic recognition becomes a dazzling highlights. According to Allied business intelligence (ABI) estimates that by 2008, RFID labels, readers and related software and services is expected to increase to as much as $ 3 billion in sales.
