What are the differences between Fastag and QR Code?

Let us understand the concepts of QR Code and FASTag to comprehend their differences in technology, applications, and functionality.

QR Codes

A QR code (Quick Response code) is a two-dimensional barcode that can encode over 4,500 characters of data. These square-shaped barcodes were initially developed in Japan by Masahiro Hara in 1994 for the automotive industry.

The primary purpose of QR codes is to store information in a machine-readable format that can be quickly scanned and decoded using smartphones or dedicated scanners.

Uses of QR Codes

QR codes are versatile and can store various types of data including:

• Website URLs and contact information

• Phone numbers and email addresses

• Payment information for digital transactions

• Authentication codes and OTPs

• Event tickets and product tracking

FASTag

FASTag is an electronic toll collection system implemented by the National Highway Authority of India (NHAI) in 2014. It uses Radio Frequency Identification (RFID) technology to enable automatic toll payments without stopping vehicles at toll plazas.

The system consists of an RFID-enabled sticker attached to a vehicle's windshield and RFID readers at toll booths. When a vehicle approaches a toll plaza, the reader wirelessly scans the tag and automatically deducts the toll amount from the linked prepaid account or bank account.

Key Differences

Conclusion

QR codes and FASTag serve different purposes using distinct technologies − QR codes use optical scanning for versatile data storage and retrieval, while FASTag employs RFID technology specifically for automated toll collection. Both systems offer convenient, contactless solutions in their respective domains.
