A big problem in e-commerce

is fake communication.

But what if you could be assured that, even if your email is compromised, your electronic communications have the authenticity of a face-to-face meeting?

And what if you could prove that authenticity to someone else?

Walrus DoubleCheck

DoubleCheck is an app that allows you to share payment instructions securely and conveniently.  


Standard practice is to email wire info and (sometimes) follow up with a phone call. 

But doing this puts you at risk for email fraud.  

Exchanging payment instructions through DoubleCheck ensures that the right person gets the right instructions. DoubleCheck is currently available for pilots and limited trials.
