Bizooma created a free QR Code generator that can be used to create codes for websites, email, paypal, bitcoin and more.
A QR Code consists of black squares and dots arranged in a square grid with white background (most commonly). Every QR-Code is unique, which can be processed using Reed-Solomon error correction, already available in our smartphone camera. One only needs to open their mobile camera and place it over any QR Code, it will automatically interpret it and show you the content it is meant to show. A QR-Code stores data in numeric, alphanumeric, byte/binary and kanji format.
QR-Code has a wide range of applications like product tracking, time tracking, item identification, document identification, and linking content. It can also work on an access control solution to allow entry after scanning a QR-Code. At this time when more and more priority is given to contactless access, QR-Code can be a solution for access control.
