• capturing a second image under a second illumination condition of visible light;
• transmitting the first image and the second image from a data reader to a connected electronic display;
• and
• alternatingly displaying the first and second images on the connected electronic display at a rate less than a minimum flicker fusion frequency for human vision.

A method of operating a scanning system to perform a document validation assist mode, the method comprising:

• capturing a first image under a first illumination condition that shows at least one security feature present on the document;
• capturing a second image under a second illumination condition that does not show the at least one security feature present on the document;
• transmitting the first image and the second image from a data reader to a connected electronic display;
• and
• alternatingly displaying the first and second images on the connected electronic display at a rate less than a minimum flicker fusion frequency for human vision to allow a user to distinguish between the images and identify the at least one security feature.
