How casinos handle cash: chips, cages, and anti-money laundering

Behind the bright lights, a casino is a tightly controlled cash business. The aim is to let guests buy in and cash out quickly while keeping every pound traceable. Most money never sits openly on tables: it is converted into chips, logged at the cage, and reconciled through surveillance and accounting. This closed loop reduces theft, speeds play, and creates an auditable record that regulators can test against transaction reports and player history.

Chips function as a controlled substitute for cash. They are issued in set denominations, often with security features, and are tracked from the moment they are sold to the moment they are redeemed. The cage acts as the financial nerve centre, handling buy-ins, redemptions, marker activity, and large cash movements under dual control. Modern systems tie chip inventory, table fills and credits, and drop counts into a single ledger, with cameras verifying disputes. Anti-money laundering controls sit across the process: identification checks for higher-risk transactions, monitoring for structuring, and scrutiny of rapid buy-in/cash-out patterns that lack a gambling rationale. Staff are trained to escalate suspicions, and records are retained to support audits and law enforcement requests.
