QR code stands for ‘Quick Response’ code. It was developed by Denso Wave Corporation in Japan. QR code is a two-dimensional barcode which is able to encode more information than onedimensional barcode. Also, QR codes are fast readable codes. The emergence of smartphones increases the use of QR code because a smart phone has features of scanning and decoding a QR code. The emergence of technology in the area of mobile internet access encourages the online marketers, newspapers and magazines to use QR codes for the advertisement of their products. These codes have various significances over traditional barcodes like greater storage capacity, fast readability, 360 degree reading, small print size, error correction, support for more languages and durability against soil and damage. Due to these benefits, the use of QR code has spread all over the world. In this paper we are generating QR code using Elliptical Curve Cryptography (ECC) in node js server.
