KYC and AML explained: what a money app must check before serving customers

Before a money app lets someone hold a balance, send money or get a card, it has to know who they are. That's KYC, know your customer, and it's one part of the wider anti-money laundering (AML) rules every payments business follows. Here's what it means in practice.

What KYC is

Checking that each customer is a real person and who they say they are, usually with a photo of an identity document and a selfie matched against it. For business customers, it also means checking the company and the people who own and run it.

What AML adds

AML goes beyond sign-up: watching for unusual payments, screening customers against sanctions lists, and reporting suspicious activity. In the UK, the Money Laundering Regulations 2017 set these duties.

What a good check feels like

Done well, it takes a couple of minutes and builds trust rather than putting people off.

  • The customer photographs their passport or driving licence.
  • They take a short selfie, which is matched to the document photo.
  • Most checks come back in minutes; a few need a person to look.

How it works on SendPay Business

Every platform includes customer identity verification, with document and selfie checks wired into sign-up, so each customer is verified before they can hold a balance or be given a card. It's included and can't be removed, because the rules and the card partner require it.
