In this modern era of the digital world, where everything is available online for purchase, RFID (Radio Frequency Identification) technology proved to be a game-changer for the retail market. RFID is a groundbreaking technology in the modern age and brought back brick and mortar stores in the game again. This astounding tracking technology is a modified and efficient version of bar code; it uses radio waves for identification of items by reading data through tags (small digital chips) attached to Itil 4 courses.
How RFID Works?
RFID operating system composed of three main components
- Scanning antenna
The scanning antenna sends RFID works by the communication of transponder and reader via radio frequency signals. When a transponder comes within the range of scanning antenna signals, the microchip on the transponder gets activated and transmits the information back to the scanning antenna. The signal received by the scanning antenna is then interpreted by the transceiver having a decoder to decode the Itil 4 certification.
Transponders used in the RFID technology are the small microchips attached to the surface of the object and are available in two versions:
- Passive Tag- do not have an inbuilt power source and are smaller in size as compared to active tags.
- Active Tag- have their power supply and can read signals even at a long distance
Whereas the scanning antennas are available in the form of handheld scanners, attached to a surface or a door frame so that it can scan people as well as objects. The scanning antenna can receive signals from multiple transponders at the same time as each transponder has a unique accession number. This property of scanning antenna enables the RFID technology to track various items at the same time.
What makes RFID technology better than barcode technology?
Barcode requires the object to be in the line of sight to be scanned, whereas the RFID is based on ‘near field’ technology that has no such limitations; it will scan all the objects that are present in the range of the scanner.
RFID technology can track multiple objects at the same time, whereas the barcode reads only one tag a time.
RFID reads 12 tags in one second, making its tremendous speed another preferred choice for the users.
Along with high speed, RFID technology offers ample storage for data as compared to the barcode.
Applications of RFID technology
The RFID technology has several applications in various sectors;
- Tracking of inventory
- Automated checkouts
- Cashless payment
- Supply chain management
- Communal/ Impactful advertisement
- Id badging
- Tracking of vehicles and airline passengers, patients and pets
RFID technology, with its immense potential, is all set to bring the retail industry to the forefront again. The use of this technology will benefit the market in enormous ways- making the shopping experience more delightful, easy, and safe for the customers. Not only will it benefit the retail market, but it will also bring marveling changes in all the sectors- making itself the necessity of future life for humans.
