The barcode Laser Scanner for identification RFID-metamorphosis

Technological innovation of the 1970s, the barcodes were developed to allow the monitoring of the product as better visibility of inventory information and improve supply chain management. The humble laser bar code scanner would follow the elements and open their position in the supply chain inventory in retail outlets.

However, for modern businesses this solution may seem rather limited. The process behind using a laser bar code scanner is a slow as bar codes are a line of linear vision technology, which required most of the time human interaction. In addition, the laser bar code are limited to the amount of information they can store. A new system had to be developed.

RFID is a wireless technology that can take the form of a small chip and can be bound to a data collection product. The use of radio waves means that the RFID chips are not required to be in direct contact with a receiver and can be tracked by location using GPS or wireless or mobile points. In addition, where the traditional barcode can be tampered with, information is the same chip. In addition, multiple tags can be read at the moment.

Features

As a relatively new technology, it is important to understand the characteristics of RFID tags that are different from traditional laser barcode scanner barcode. First, the memory is defined as the ability to read and write to the tag. A read-only tags often includes a unique identifier, such as the product code. The distance that can be read the RFID tag is always increased, and it is important to note that the high-frequency tags have autonomy, currently about 1 metre, while the low-frequency tags have a range of less than 25 cm. Finally, the smart tags are powered with an internal battery, but to maintain profitability and form small, passive RFID tags are powered by the reader.

Real-world applications

Since RFID tags are improving detection capabilities and the ability to transmit information, it is possible for the regulation of products or the stock market. Boxes of fish, the physical product that moves his way through the supply chain, temperature may be monitored or whether if it was stored correctly. If one of parameters of configured is violated, as a nominal temperature increase, an alert can be sent via SMS or another form of communication.

At the end of the Barcode Laser Scanner?

One of the aspects of supply chain improvement increases the effectiveness of sending and receiving of the goods. For example, a number of large retailers now requires suppliers to use RFID tags for goods, such as pallets, to allow the management of the stocks held in a much more effective on the retail site. Providers can label their goods when they leave the warehouse with information such as the identification of priority levels and stock to manage information.

RFID tags are extremely powerful devices that certainly have their advantages. However, just like laser barcode scanners and barcode, RFID tags should be standardized to allow effective communication between devices.
