The difference between the electronic tag and bar code technology and cost

In recent years, RFID because of the remote reading with high storage capacity and other characteristics have attracted much attention. It not only helps companies to dramatically improve a cargo information management efficiency, but also allows Internet sales companies and manufacturing companies, which more accurately receive feedback information, the control information needs, optimize the entire supply chain.

The difference between a cost of

Because of the different components, intelligent barcode label is much more expensive than the cost of bar code is a bar code paper and ink costs, while active RFID tag memory chip prices more than $ 2, passive RF tag costs are more than $ 1. But there is no built-in chip price tag of only a few cents, it can be used not so high in the case of data requirements, but also has a bar code does not have the security features.

Two technical difference

Conceptually, the two are very similar, the goal is to quickly and accurately confirm the tracking target object. The main differences are as follows: Have written information or the ability to update memory. Barcode memory can not be changed. RFID tags, unlike bar codes, its unique barcode scanning can not be copied. The tag is not only confined to the field of view, because the information is transmitted by the radio waves, and the bar code must be within the field of view. Due to the low cost of barcodes, a sound standard system, has spread around the world, it has been generally accepted, the whole, RF technology is only confined to the limited market share. Currently, a variety of bar code control templates already be in use, in terms of access to information channels, radio also have different standards.
