What is FASTag and How Does FASTag It Work

What is FASTag?

FASTag is a tag that will be fitted on your vehicle’s windshield. It will pay the toll automatically when it crosses the boom barrier of the toll plaza. People who bought their vehicles over the last few years come with the FASTag pre-installed. If you haven’t enabled it yet, fret not, one hybrid lane will still accept cash.

Getting to the point, a FASTag is a device that equips RFID or Radio Frequency Identification technology. This is the same piece of tech that is used in transport access-control systems, like say a Metro smart card. This will make payments at the toll easy. The amount of the toll will be deducted from the prepaid or savings account linked to the FASTag. It is advisable that it is attached to your car’s windshield so that whenever you drive your vehicle through toll plazas, the amount will be automatically deducted, without stopping for making cash purchases.

Once you buy FASTag, which I will explain in detail below, it will have validity for up to 5 years. You will need to recharge or top it up once you exhaust the minimum limit. You will receive updates through SMS for all the toll transactions, low balance, etc. As of now, over 450 toll plazas across India support the FASTag technology.

To attract more people to use this feature, a 2.5% cashback will be given to users for 2019-2020. Moreover, a one-time fee of ₹100 will be deducted as it is required for FASTag account activation. This fee is charged depending on the payment method. Keep in mind that one FASTag will be valid for just one vehicle. So if you own more than one car, it is imperative that you get FASTag for all the vehicles.

Union Minister for Road Transport and Highways, Nitin Gadkari, even referred to FASTag as the ‘Aadhaar’ for vehicles in the country. He added that the present architecture already supports over six million tags with nearly 10 lakh transactions on a daily basis.

How does FASTag work?

FASTag is operated by the National Highway Authority of India (NHAI). As mentioned earlier, FASTag works with the help of Radio Frequency Identification (RFID) technology. The National Payments Corporation of India (NPCI) has formed the National Electronic Toll Collection (NETC) program that aims to meet the electronic tolling conditions in the nation. FASTag acts as its backbone. This RFID-powered technology will make toll payments while the vehicle in motion, which completely avoids the need for cash payments and a long queue.

The Electronic Toll Collection (ETC) infrastructure will capture aspects of your car, such as Tag ID, vehicle class, registration number, and owner name at the toll plaza. These details are then sent to the bank for further processing. The bank then forwards the request to the NETC Mapper to validate the tag details.

After successfully validating the captured details, the merchant bank or the acquirer that communicating with the toll plaza system computes the relevant toll fare and then initiates a debit request to the NETC system.

What are the benefits of FASTag?

FASTag enables a lot of benefits. They include not carrying cash, time-saving, could save petrol which would be used a lot in a queue.

FASTag by the NHAI is extremely simple to use. It is a reloadable tag that enables automatic deduction of toll charges when a vehicle crosses the toll gate. This lets a driver pass through a toll plaza without stopping for cash transactions to pay the charge. FASTag is linked to a pre-paid account.

FASTag is attached to the windscreen of your car. So every time you drive through the toll plazas, the toll amount will be deducted without you stopping for cash transactions.
