Method and system for identifying a security document

摘要

A method is provided of identifying a security document using an identifying device. The identifying device is provided with a capacitance sensor and a second sensor. The method includes capacitively coupling a first element of the security document with the capacitance sensor and obtaining first data from the first element using the capacitance sensor. Second data is also obtained from the security document using the second sensor. Output data is then generated based upon the first and second data. A corresponding device and system are also presented.
