These are the ideas the rest of the documentation assumes you understand. Read them once before working through the guides.

• Enroll vs verify vs identify — which operation fits which problem.
• Capture session lifecycle — the state machine every capture follows.
• Capture modality — contactless vs scanner.
• On-device quality scoring — why scoring happens before the network call.
• Liveness and anti-spoof — what the model checks and what it does not.
