Abstract

There is described a method of reading an optically readable security element using an image capturing device. The method comprises, by the image capturing device, reading the optically readable security element, optically determining a physical characteristic proximal to the optically readable security element, the determining being distinct from the reading, comparing the determined physical characteristic to an expected physical characteristic and calculating a correspondence between the determined physical characteristic and the expected physical characteristic.
