A growing number of checks add a selfie or a short video, taken on the phone camera while the player holds the document or turns the head on request. Software compares the face with the photo on the document and looks for signs of a printed or replayed image. The step takes a minute in good light. A failed match usually allows another attempt before a person reviews the case by hand.
Identity documents are sensitive, and they belong only in the upload area of the account or in the secure form support provides. Sending them by ordinary email or through the chat window leaves copies in places that are harder to protect. The privacy policy says how long the casino keeps them, usually for several years after the account closes, as the rules on money laundering require. Covering details the check does not need, such as spending lines on a bank statement, is usually accepted.
A passport, a national identity card or a driving licence covers identity at almost every casino. The document has to be valid, fully visible with all four corners in the frame, and readable without glare. Some casinos want both sides of a card. A second document, such as a utility bill, a bank statement or an official letter from the last few months, confirms the address. The accepted list sits in the verification section of the terms.
