1. Fastag :
Fastag has revolutionized the way toll taxes are paid. It has been developed by the national payments Corporation of India and is used by the National Highway Authority of India the government institution that handles the highways. It is a printed tag that uses the RFID Technology for the electronic collection of taxes.

2. Barcode :
Numbers can be stored in a pictorial format using barcodes which make use of lines and spaces. This concept was developed in 1952. Today, it is used for tracking parcels and nuclear wastes, tracking airlines luggage, billing in stores etc. The barcodes are scanned by barcode scanners to retrieve the numerical data.

3. Near Field Communication (NFC) :
NFC technology is developed on the principle of inductive coupling of connected devices. It is a standard to communicate between wireless devices. It is designed to be used within a short range. It is used in identity cards, keycards, and by cashless payment providers.
