The use of Quick Response (QR) code has proliferated with growing number of mobile consumers and a wide range of applications including advertisement, product labelling and tracking, access control, and mobile payments etc. However, being a static image, a QR code can be replicated or altered easily posing a security challenge while using it for sensitive applications, for instance, payments and access control. Visible light communication (VLC) or Li-Fi, which uses modulated LED light to transmit data that can be captured via the CMOS image sensor on a smartphone, presents an ideal opportunity to substitute traditional static QR code with an LED light based QR code. This type of light based QR code (LiQR) is secure and can be dynamically programmed for improved security as well as cover a wider range of applications.
