Difference between Fastag, QR Code and NFC

1. Fastag :
Fastag provides a new way of paying toll taxes by scanning the tag using a scanner. The toll tax is deducted directly from the bank account of the driver. This makes the collection and paying of the toll taxes hassle free and much quicker than traditional cash methods.

3. Near Field Communication (NFC) :
NFC is a method of close distance communication and data transfer using the inductive coupling of the antennas in the devices. It provides rules for communication between the two connected devices. It is a relative new technology and was developed in 2002 by Franz Amtmann and Philippe Mangars.
