RFID V/S Barcode

Radio Frequency Identification (RFID) is a wireless communication technology that can define particular objectives and read and write associated information via radio signals without creating mechanical or optical contact between identification scheme and particular objectives. Radio signals are transmitted from RFID tags attached to objects by electromagnetic fields tuned to radio frequencies to automatically identify and track the objects.

Barcode technology is the abbreviation of barcode auto-identification technology. It is an automatic technology for the recognition of symbols based on modern IT. It can incorporate symbol coding features, data acquisition, automatic identification, information input, and storage. It can efficiently fix the issues of big amounts of at acquisition and automatic input in the logistics system.

The advantages of RFID technology over barcode technology:

1. RFID tags are more secure:

Because RFID carries electronic information, it’s data content can be protected by encryption technology, so that its content is not easy to be forged and altered, while barcode is exposed to physical information, and the use of common coding rules, data security can not be guaranteed.

2. Higher efficiency of RFID:

The recognition frequency of barcode scanning is limited, only one barcode can be scanned at a time, and the RFID reader can identify and read several RFID tags at the same time.

3. The storage capacity of RFID tag Data:

The capacity of the one-dimensional barcode is 50 bytes, the maximum capacity of the two-dimensional barcode can store 2 to 3000 characters, and the maximum capacity of RFID is several megabytes. With the development of memory carriers, data capacity is also expanding. In the future, the amount of data needed to be carried by articles will be increasing, and the demand for expanding the capacity of storage media will increase accordingly.

4. Anti- Pollution ability and durability of RFID tags:

Traditional barcode carriers are paper, so it is vulnerable to pollution, but RFID has a strong resistance to water, oil, and chemicals. In addition, because the bar code is attached to plastic bags or cartons, it is particularly vulnerable to damage; the RFID label is the data stored in the chip, so it can be free from contamination and prolong service life.

5. The external forms of RFID tags are various:

RFID is not limited by size and shape in reading. It does not need to solve the size or printing accuracy of the carrier in order to read accurately. In addition, RFID tags can be used in different products with the development of miniaturization and diversification.

6. RFID Technology can be re-used:

Traditional barcode carriers are paper, so it is vulnerable to pollution, but RFID has a strong resistance to water, oil, and chemicals. In addition, because the bar code is attached to plastic bags or cartons, it is particularly vulnerable to damage; the RFID label is the data stored in the chip, so it can be free from contamination and prolong service life.

7. RFID is more penetrating and accessible:

In the case of coverage, RFID can penetrate non-metallic or non-transparent materials such as paper, wood, and plastics, and can carry out penetrating communication. The barcode scanner can recognize the barcode only at close range and without object obstruction.
