What is RFID identification technology?
RFID stands for radio frequency identification. Today, the need to automatically identify elements and collect data and information related to them without the need for human intervention is felt in many industrial, scientific, service and social fields, so for this purpose, various technologies such as barcodes, smart cards, recognition Voice, some biometric technologies, OCR and RFID have been designed and implemented. “RFID” is the title of the newest identification technology and one of the top 10 technologies in the world in recent years.
The function of RFID depends on two tag and code reader devices, which use radio waves to communicate with each other and store the serial number attributed to a person or object inside a microchip (RFID tag). Using the antenna tag, the necessary information to identify the desired item is sent to a code reader.
The RFID code reader is usually connected to a computer and has the same role as a barcode scanner. When the tag is placed near or within the range of the code reader, the magnetic field produced by the code reader activates the tag.
- Due to the fact that tags are presented in different sizes and shapes, users can choose one of them according to their needs.
- Tags can be hidden or embedded in most materials
- In order to read the code, it is not necessary for the tag to be in direct view of the code reader
- Due to the nature of tags (no need for direct contact), there will be no wear and tear
- It will not be possible to manipulate the serial codes stored in the tags
Applications of RFID
RFID technology is used in many office buildings and in order to control the movement of employees in authorized and unauthorized departments. A large number of goods sellers use this technology to protect their products electronically against theft. Some government institutions also use the above technology to monitor and control offenders.
Other applications of RFID technology:
- Inventory control
- access control
- Laboratory analysis
- Controlling the number of laps (for example, automatically recording the number of times a runner goes through)
- Record the time and place of traffic (for example, automatic registration of the time and place of patrolling for some special jobs)
- Vehicle identification
- Security of buildings
- Traffic control, tracking of offending drivers and automatic registration of violations
- Transporting airports, highways, locating cars, checking passengers’ luggage and issuing flight tickets
- Supply chain management, warehousing, property control, production cycle control, sales and trading, after sales services
