The DOCUMENT LIBRARY is a collection of pictures of 240 government documents (ID, passports, drivers licenses, residence permits, visas). Additional videos for 146 documents are comprised, showing their principal security feature, a diffractive optically variable image device. The SDK is ready for full integration into your existing android or iOS app.

The DOCUMENT LIBRARY SDK lends itself to a variety of uses, from the mobile devices of executive forces and police officers to border control situations, from deployment by governmental or private security services to supporting the work of document forensics experts. Last but not least, it adds value to existing products and services of IT integrators or governmental software providers. 

The DOCUMENT LIBRARY SDK is the means of choice when it comes to the unambiguous authentication of identity documents. Whether foreign or national, offline or online, the SDK provides all the tools and information for the user that he needs to verify the principal security feature of the document, thus establishing with great certainty the authenticity of a document and its holder. Unknown foreign documents or security feature details can be identified beyond doubt, and the SDK helps to establish clarity regarding suspicious-looking security elements or ID documents. The need for time-consuming and expensive deployment of highly skilled staff and specialized teams is greatly reduced.
