The FactChain Pen is a mobile application available on Google Play and Apple Store. The FactChain Pen brings two-factor digital signing and verification to any product using it.

A digital signature guarantees the authenticity of an electronic document or message in digital communication and uses encryption techniques to provide proof of original and unmodified documentation. An electronic signature is not the same thing as a digital signature. An e-signature can be falsified.

Absolutely. We tried to make it as easy as possible to use the Pen for your own applications. Head over to and register your application. There is some sample code and documentation for developers here
