What is it ?

• To Regulate traffic in the tollgates, which has resulted in increasing cost of logistics, the Union Ministry of Road Transport and highways has launched FASTag.

How Does it work?

• It is one of the application of Radio-Frequency identification (RFID) Technology when a car crosses the tollgate, the car is affixed with a Tag on her windscreen which gets scanned automatically and no need to stop the car.
• The Tag is scanned by the workers om Electronic toll collection lanes and the toll tax is deduced from the respected bank that he/she provided.
• Finally a message is sent from the bank for acknowledgement.

Radio-Frequency Identification Technology:

• It is a wireless communication technology which incorporates use of electromagnetic coupling in a radio Frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person.

Radio-Frequency Identification Technology:

• It is a wireless communication technology which incorporates use of electromagnetic coupling in a radio Frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person.
• Works from low frequency (30Hz) to Ultra high Frequency upto micro-wave frequency (2.45 GHz)

Challenges:

Reader Collusion:

• When a signal from one RFID Reader interfere with other, Prevented using Anticollission Protocol.

Tag Collusion:

• When too many tags confuse RFID, this collision happens, especially while transmitting data at same time.

Applications:

It is increasingly used in internet of things, combining RFID with smartphone GPS can transfer sensor data including temperature, movement and location to be wirelessly transmitted used for people tracking from hospitals to track their patients to documents.

Health Care:

Used to reduce medical errors, meeting new standards, staff shortages and reducing costs can be done by RFID.

Government Library:

RFID Technology used to read barcodes used in library to browse multiple items simultaneously.
