Fraud in Instant Payments: Detecting the Undetectable
Instant payments are irrevocable and settle in seconds. That is wonderful for customers and a gift to fraudsters, because the overnight batch review that used to catch bad transactions no longer has time to run.
The 400-millisecond problem
When a payment clears in under a second, fraud decisioning has to happen in-line, before authorisation. That means real-time feature computation, a model that scores in milliseconds, and a policy engine that can hold, step-up or decline without adding perceptible latency.
Behaviour beats blocklists
Static rules and blocklists cannot keep up with authorised push-payment scams, where the customer themselves is manipulated into paying. Behavioural signals — device, session, payee history and velocity — catch the anomalies that a rule never anticipated.
Design for recovery too
No model catches everything. Fast confirmation-of-payee, transaction limits for new payees and a rapid recall workflow limit the damage when something does slip through.
