Introduction to RFID
RFID stands for rf facial machine identification and is a technology that uses radio waves as signals for the exchange of information between a reading system and an electronic label attached in a remote location. This technology is frequently utilized for identification and for monitoring. RFID is a relatively new technology used for stock, logistics, in libraries, hospitals and also in people.
The basic technology of the device requires reading tags and equipment between which information is communicated through radio waves. There are 3 Kinds of tags available in RFID:
Passive tags don’t have any power source, active tags are battery operated and also the battery aided passive tags which need an outside source to work.
RFID tags consist of a circuit that stores data and reads signs and an antenna for receiving and sending signals.
Uses of RFID
Mobile RFID – RFID finds applications in many different businesses and public platforms. The first utilization of RFID is in mobile telephones, where patrons may request an RFID tag which sends and receives promotion signals and payment choices.
Automotive RFID – The second use of RFID is in transport payments. Some authorities use RFID to restrain traffic management and product direction. The automotive industry also uses RFID for zip cards, season parking tickets, and e-toll payments. Buses and public transport in certain nations use RFID cards for their bus, rail, and subway transportation.
RFID in Business – Used in asset management and product tracking.
Organizations can track and manage their assets using RFID tracking devices. Web based monitoring devices allow companies to track their assets and take decisions anywhere in the world. RFID for product monitoring employs the technology in the production department directly to the revenue division. RFID systems use Auto-ID Labs for inventory management.
Used in transportation and logistics – The regions where RFID is popular in transportation are lawn management, freight and shipping, and distribution centers. Aerospace technology, airlines, railroad, and air freight identification all use RFID technology.
Library RFID – Certain libraries have shifted from barcodes for their books to RFID tags because of their books, CDs, and DVDs.
Passport RFID – Certain South Asian countries and the US have begun implementing RFID tags to citizens’ passports to identify and track the passenger count and to prevent terrorism.
Benefits of RFID
RFID is a very efficient technology and it’s easily accessible all around the world. It also offers a superior form of electronic article surveillance (EAS), and also a highly developed self checkout process for consumers. The tech is comprehensive, advanced and automatic. A lot of information can be conveyed with the help of RFID. It matches the bar code system. It is cheap, cost effective and universal. RFID radio wave frequencies can be easily controlled and standardized by the respective authorities.
