What is RFID

Radio Frequency Identification Technology or RFID technology is an extremely powerful and cost effective technology that allows a wide range of objects (including people) to be automatically identified, tracked and managed without any human intervention. It provides a contact-less data link, without need for line of sight or concerns about harsh or dirty environments that restrict other auto ID technologies such as barcodes.

RFID technology is based on the use of small tags that vibrate to generate radio waves in a desired wavelength and frequency or transponders and readers for connection to an information system. The tag includes a chip and an integrated antenna which is activated by a radio signal with preset frequency which in return sends a signal to the activator. The reader/encoder acting as a transceiver can read and write information on the chip. Tags are data carriers unlike barcode labels which are ID's only.

Tags can be produced in any shape that suits the chosen application and easily integrated into the item to be tracked.

Most companies are aggressively adopting RFID technology for managing security, access control, logistics and real-time information

With increasing business benefits, decreasing costs and more and more applications and solutions becoming available, Radio Frequency Identification (RFID) is steadily finding acceptance and adoption across verticals. Retail ports, industries, warehouses , parking lots, toll roads, travel/car fleet units, banks, airports, judiciary and government are a few of the significant adopters of this technology. While priorities vary for industries, the bottom line expectations essentially stay the same. Most companies are aggressively adopting RFID technology for managing security, access control, logistics as well as real time information access and update with tags, sensors, readers and state-of-the-art business application systems.

RFID uses radio frequency waves to transfer data between a reader/scanner and a movable item to identify, track or locate it. RFID does not require physical sight or contact between the reader and the tagged item, making it more efficient than traditional bar codes. However, it is not merely a better substitute for bar codes, RFID as a technology has varied applications across industries and business functions.
