AML, anti money laundering, is the body of law and controls that obliges financial institutions to detect and report attempts to move criminal proceeds through the financial system. In card payments it drives transaction monitoring, sanctions screening, suspicious activity reporting and the prohibition on processing for undisclosed businesses.
Why it matters
AML is the legal backbone behind most of the questions merchants find intrusive: source of funds, ultimate beneficial owners, why your refund rate spiked, who your affiliates are. It is also what makes transaction laundering, processing another company’s sales through your merchant account, one of the fastest routes to termination and a MATCH list entry. Regulators fine acquirers heavily for AML failures, and every enforcement action tightens the questionnaire the next merchant receives. Answering fully and consistently is not just compliance; it is what keeps your file out of the escalation queue.
