Abstract
A method of processing documents of value. The method including detecting a visible pattern on at least one side of a document; detecting the response of at least one side of the document to infrared radiation; comparing the detected visible pattern to one or more predetermined patterns and identifying the document if the detected visible pattern is sufficiently similar to the or one of the predetermined patterns; and determining from the response to infrared radiation if the document is authentic.
Claims13
Apparatus for processing documents of value, the apparatus comprising a visible pattern detection system for detecting a visible pattern on at least one side of a document;
- an infrared response detection system including at least one infrared detector and infrared emitter for detecting the response of at least one side of a document to infrared radiation;
- and
- a processor for comparing the detected visible pattern to one or more predetermined patterns so as to identify the document if the detected visible pattern is sufficiently similar to the or one of the predetermined patterns, and for determining from the response to infrared radiation if the document is authentic.
A method of processing documents of value, the method comprising:
- a) detecting a visible pattern on at least one side of a document;
- b) detecting the response of at least one side of the document to infrared radiation;
- a) comparing the detected visible pattern to one or more predetermined patterns and identifying the document if the detected visible pattern is sufficiently similar to the or one of the predetermined patterns;
- and,
- d) determining from the response to infrared radiation if the document is authentic.
