When you set up an appointment with a stranger, how can you be sure that they are who they say they are or even whether they are a dangerous criminal?

Our patented system deploys the analytical and secure-data resources of IBM Watson & the Ethereum Blockchain to provide you with better-than-bank levels of reliability and security at only $1.99 per registered client.
