How it works
Here’s how Passwave works:
Once a visitor is verified, they’ll use a QR code to access your website services
Passwave sends confirmation to you that they’re verified
It’s proof that the website visitor is a real person, has shown government-issued ID and is over 18
Uniquely, we give users a choice of recommended ID verification providers. All have solid cybersecurity track records and minimal data retention policies. Passwave stores no document scans at all.
To prevent fraud, users provide regular selfies. We check these against a vector sheet created when they first verify.
