The Difference Between RFID Scanning Technology and Ordinary Bar Code Technology

  • August 24, 2017

Shenzhen remote rfid reader manufacturers that the two also have a lot of the same place and different places, can be used to track the target body. In fact, the biggest difference is: bar code is a visual technology, the scanner must be under the control of manual work, can only receive a fixed range of bar code. And then the bar code is the optical signal, RFID is the electromagnetic signal, the same point: are fast and accurate to track the target object. Are printed with bar code, can be used for bar code recognition.


The detailed differences are as bellow:

1. Scan quickly

The RFID reader can simultaneously read and read multiple RFID tags, while the barcode can only have one barcode scanned at a time.


2. Small size and shape diversification

RFID is not limited by the size and shape of the read information, so it is not necessary to match the fixed size and print quality of the paper for the purpose of reading accuracy. In addition, RFID tags are more portable and diversified in order to be used in different products.


3. Anti-pollution ability and durability

The traditional barcode carrier is paper, so it is susceptible to contamination, but RFID is highly resistant to water, oil and chemicals. In addition, because the bar code is attached to the plastic bag or packaging cartons, it is particularly vulnerable to damage; RFID tag is the data stored in the chip, it can be free from fouling.


4. Reusable

Today's bar code printing can not be changed after the change, RFID tags can be repeated to add, modify, delete the RFID tag stored in the data to facilitate the update of information.


5. Penetrating and barrier-free reading

In the case of coverage, RFID can penetrate non-metallic or non-transparent materials such as paper, wood and plastic, and be able to communicate with each other. And the bar code scanner must be in close proximity and no objects blocked in order to be able to identify the bar code.


6. The memory capacity of the data is large

One-dimensional bar code capacity is 50Bytes, two-dimensional bar code maximum capacity can be stored 2 to 3000 characters, RFID maximum capacity is the number of MegaBytes. With the development of memory carrier, data capacity has also been expanding trend. The amount of information required for future items will be increased, the volume can be expanded capacity.


7. Safety

Because RFID is carrying electronic information, its data content can be password protected, so that its content is not easy to be forged and altered. In recent years, RFID because of its long-distance read, high storage capacity and other characteristics of high-profile. It can not only help a business to significantly improve the efficiency of goods, information management, but also allows sales companies and manufacturing enterprises to interconnect, so as to more accurately receive feedback, control demand information, optimize the entire supply chain.
