What does the barcode on the FASTag mean?

The barcode present on FASTag is simply a machine readable version of the FASTag's information. In normal case when your car passes through the toll gate, the FASTag RFID (Radio Frequency Identification) sticker that is affixed to your windscreen becomes active. It sends data, including your unique ID, to the receiver unit, which inturn processes the information and deducts the appropriate amount from your wallet. However, if that doesn't work, the FASTag is manually scanned by a person using a barcode scanner. When the tag is successfully scanned, the scanner attached to the system deducts the toll money instantly from the digital wallet linked to your FASTag.

The management of FASTag accounts is done using this barcode. They make it possible for administrators or users to scan the code for updates to account data via FASTag applications or systems, balance checks, or account verification. Users may easily access and manage their FASTag accounts with the help of the barcode. They may efficiently do a variety of account-related operations by scanning the barcode using FASTag mobile apps or devices that the issuer provides.

What is Barcode?
A barcode is an optical data representation consisting of dots, bars, or parallel lines that may be read by a scanner. The information it encodes may be quickly decoded into a form that can be read by a device, such as a barcode scanner or a smartphone camera with a barcode reader app. Many applications, such as Product Identification, Inventory Management, Document Tracking, Electronic Ticketing and Payments, etc., make extensive use of barcodes.
