Express yourself, reduce fake

This is brilliant. If everyone signed and sealed their digital and social communications then this world would look dramatically different. Facebook should buy this keyboard, issue it to their users and save themselves about 1,000 cyber engineers. It is brilliant.

Using on my emails! Personalized

I now sign my emails for work in real time with ease of a verified keyboard. This is like the Grammarly for signatures on everything you write, anywhere! SignID is going to be huge with such an innovative approach to help reduce fake! Love it
