Compliance.

In plain English

Compliance is how a business makes sure it follows the rules that govern it, from anti-money-laundering laws to consumer-protection and privacy requirements. At banks it is an entire department, because the penalties for breaking financial rules are severe and the rules are dense. Compliance staff build the systems that monitor transactions, verify customers, and file required reports. For customers, compliance is mostly invisible until it shows up as identity checks or questions about a transaction.

02The math, step by step
