Determining the source of an optical code presented to an optical code scanner

摘要

A device, method and system is provided for determining if an optical code (300) is presented to an optical code scanner (105) in either a printed form or on the display of an electronic device. Certain presentation characteristics of an optical code (300) are different depending on whether the optical code (300) is presented in printed form or on the display of an electronic device. The changes in the presentation characteristics require changes to certain parameters of the optical code scanner (105) for the optical code (300) to be read.
