KYC (know your customer) is the process of verifying a customer's identity before and during a financial relationship: collecting and checking things like name, address, date of birth, and identity documents. AML (anti-money-laundering) is the broader set of obligations to monitor activity and report transactions that look like money laundering or other financial crime. These are message-and-control layers, not money movement: they decide whether an account opens, stays open, or gets frozen, and they sit around the edges of nearly every flow. Banks, payment companies, and program managers all carry some version of these duties, with the exact rules set by each country's regulators and law.
In a flow
KYC usually happens at onboarding, before a party can send or receive funds, and AML monitoring runs continuously in the background on the flows that follow. In a typical sponsored program, the program manager and its sponsor bank share responsibility for verifying customers and watching transactions. None of this moves money itself; it gates and watches the money legs that the banks execute.
Common misconceptions
Myth: KYC and AML are the same thing.
Reality: KYC is one part of AML. KYC is mainly about verifying identity at onboarding; AML is the wider program of ongoing monitoring, record-keeping, and reporting that KYC feeds into.
Myth: Only banks have to do KYC and AML.
Reality: Many non-bank players (payment processors, program managers, crypto on-ramps and off-ramps) carry obligations too, though who is ultimately responsible depends on the structure and the jurisdiction.
