Abstract
A system including: a document holder configured to receive a document; one or more optical sensors directed toward the document holder; one or more processors; and at least one memory having stored thereon computer program code that, when executed by the processor, instructs the processor to: control the one or more optical sensors to capture a plurality of images of the document within the document holder; identify a feature of the document within each of the plurality of images, the feature having visual characteristics that differ based on an angle at which the feature is viewed; and output, in response comparing the respective visual characteristics of the feature of the document in each of the plurality of images to corresponding expected visual characteristics of the feature for the document, an indication of a verification of the document.
