Caisson Doublecheck API

Securely scan, extract, and verify your identity data

The Caisson Doublecheck API (beta) instantly and securely scans any United States-issued driver’s license and returns the data in a machine-readable JSON format, and verifies that the license data matches the embedded data, and checks that the faces are the same person.
