FASTag Scanner: What is it and How it Works

FASTag is a cashless payment system that uses RFID technology to collect toll taxes at national highway toll plazas. It helps to prevent long queues and traffic congestion. Since February 16, 2021, all four-wheelers must have a FASTag fitted on their vehicles.

The system is operated by several banks under the supervision of NPCI and NHAI. FASTag eliminates manual toll collection, making the process faster and more efficient for drivers, saving time and effort.

What is a FASTag Scanner?

A FASTag scanner is a device installed at toll gates on Indian national highways. It enables cashless payment of toll taxes for users passing through toll booths. With a FASTag, you can drive through the toll plaza without stopping to make a cash payment. The scanner reads your FASTag while your vehicle is in motion and deducts the toll amount from your linked bank account.

How Does the FASTag Scanner Work?

Once a four-wheeler owner purchases a FASTag and affixes it to the windscreen of his/her vehicle, he/she becomes eligible for a seamless driving experience across all toll plazas over the Indian national highways. Let’s understand how this works:

  • The FASTag is linked to the user’s prepaid account and is then fixed to the windscreen of his/her vehicle. Here’s how you can stick FASTag to your vehicle!
  • With the use of Radio Frequency Identification (RFID) technology, the FASTag scanner scans the tag affixed on the vehicle and automatically deducts the toll amount from the linked prepaid account
  • The technology works such that the vehicle does not have to stop at the toll gate; the amount gets deducted as the vehicle passes through it
  • Your prepaid FASTag account will then be debited for the transaction

What Happens if You Don’t Have a FASTag on Your Vehicle?

Since 16 February 2021, the Government of India has made it mandatory for users to have FASTag installed on their four-wheeler vehicles. If, somehow, you don’t have the FASTag installed on your vehicle, you will have to pay twice the toll tax amount at every toll plaza that you cross across the Indian national highways.

How does the FASTag scanner work?

The scanner uses RFID technology to read the tag on the vehicle, automatically deducting the toll amount from the linked prepaid account.

What if I don't have FASTag installed?

Without FASTag, you will have to pay double the toll tax amount at every toll plaza on Indian national highways.

How do I attach FASTag to my vehicle?

Remove the adhesive liner from the sticker and affix it on the inside of the windshield behind the rearview mirror, with the adhesive side facing outside. Press gently to secure it.

How do I recharge my FASTag?

If you have linked your FASTag to your Paytm mobile app, you can recharge it by adding money to your Paytm FASTag account. The toll amount will be deducted automatically when you pass through a FASTag-enabled toll gate.

NHAI to Implement GPS-Based Toll Collection System, Replacing Existing Toll Plazas

The National Highways Authority of India (NHAI) is preparing to implement GPS-based toll collection systems by March 2024, aiming to replace existing toll plazas. Pilot testing of the technology will start on select highways. The GPS-toll collection system tracks a vehicle's movements and calculates toll charges based on the distance covered, offering a more equitable approach compared to fixed tolls. It also eliminates the need for cash or change, as the toll amount is automatically deducted from a linked account using a secure electronic payment system. This initiative aims to alleviate traffic congestion and enhance the accuracy of toll collection.

Incomplete KYC FASTags to Be Deactivated After January 31, 2024

Starting from January 31, 2024, FASTags with incomplete KYC will be deactivated by banks, according to the National Highways Authority of India (NHAI). NHAI has introduced the 'One Vehicle, One FASTag' initiative to improve the efficiency of the electronic toll collection system and facilitate smoother movement at toll plazas. This initiative discourages the use of a single FASTag for multiple vehicles or linking multiple FASTags to one vehicle. NHAI is urging FASTag users to complete the KYC process as per RBI guidelines by updating their latest FASTag. Users must ensure that their latest FASTag has completed KYC to avoid any inconvenience. Previous FASTags should be discarded, and only the latest one will remain active after January 31, 2024.
