Abstract

An information handling system analyzes secondary information captured with an image of a two-dimensional barcode to perform a function. For example, a mobile phone camera captures an image of a QR code at a product plus characters printed next to the QR code, uses optical code recognition to determine the characters, and applies information from the QR code and the characters to register the product. As another example, a security indicator is captured with an image of the QR code and applied to access information of the QR code, such as by using GPS position information, local network information, or telephone number information to encrypt and/or decrypt information stored in the QR code.
