Radio Frequency Identification (RFID) what is it? How does it work?

With the tremendous technological development around the world, facilitating work for companies and tracking goods and mechanisms has become extremely important.

Primitive technologies such as barcodes or QR codes are no longer adequate due to the inability of these symbols to contain a large amount of information or to control it remotely and many other problems, therefore, a new technique appeared called: Radio wave identification

However, what is this technology and how does it work? And what is the use of it?

Radio wave identification is a technology that helps in tracking and monitoring objects and recording some information about them. It works through small chips that can be implanted in machines or even living bodies, but most of their use is for industrial or commercial goals of organizations.

The RFID technology consists of:

1-  RFID Tag (TAG)

2-  RFID Reader

3-  Antenna

4-  A computer system to analyze the incoming data

The RFID tag contains the antenna built into it, which enables the information to be easily read by the RFID reader.

The radio waves arrive from the tag to the reader and from the reader they are sent to the computer to be stored and analyzed. There are two types of RFID chips that can be distinguished.

1-  Passive RFID chips

2-  RFID chips equipped with batteries

Each of them has specific advantages and uses, and the difference between these two types is quite large from a cost perspective, as passive RFID chips can be provided at very low prices and certainly with the abandonment of some features and we will explain about this in a separate article ةore broadly.

As for this technology, it has become completely in control of transactions in recent years and has even defeated its direct competitor from the interface, which is the barcode system; because of its superiority over it in many aspects, but what are the things that distinguish the radio wave identification system from the barcode and make it a unique system?

• Dozens of times more information can be stored on RFID chips than barcode labels.

• Barcode labels can be easily damaged or destroyed resulting in loss of information, while RFID is safer and is not easily perishable.

• Barcode cannot be read remotely, as it requires a very short distance, while RFID provides easy reading and remote tracking.

• The barcode can keep the information of one thing or product only without distinguishing each piece separately, while RFID can give specific information about the location of each chip without generalization.

• You can read many products or goods at one time by the RFID system, unlike the barcode that needs to scan the goods separately.

Radio wave identification technology can be used in many ways from things related to security or car license plates to commercial or industrial uses such as:

RFID technology in warehouse management

RFID technology in asset and logistics management

RFD in Vehicle Management

RFID in sales and shopping fields

With this amazing development and with the saving of time and effort that is happening in the world, it has become one of the necessary things to use RFID and move from the stage of using barcodes for easier and better use of radio wave identification technology.
