Abstract

Now a days Quick Response (QR) codes are used everywhere, we can see them on posters, magazine ads, websites, product packaging and so on. Maximum storage capacity of QR code using only two colors (black & white) is 4296 characters in version 40. This capacity can be further improved by considering more colors along with black and white i.e.; red, blue, green etc. or by using multiplexing technique. In this paper a new color QR code generation algorithm is proposed, which uses both multiplexing technique and color coding technique. This algorithm increases the QR code capacity by 3 times compared to the present black and white QR codes. QR code damaged up to 30% can be efficiently decoded using RS codes. The codeword of RS code is generated using finite fields.
