Predict identity checks before shoppers lose their checkout

You’re the ai / ml engineer. Your team is in the room. Printed Oct 9, 2026.

An earlier identity check protects checkout continuity but can add friction for shoppers who would have cleared normally.

The checkout path must collect a stronger signal before approval without making routine interest-free plan selection feel less immediate.

Who you’d be doing this for

“I picked the plan, then got bounced into another check and my cart timed out.”

What is at stake

Late identity checks interrupt shoppers after they select an interest-free plan. You must weigh earlier fraud signals against unnecessary checkout friction.

Why it isn’t already fixed

Every obvious fix costs something else. That’s the part you’d have to decide.

  • earlier identity signals vs. unnecessary shopper friction
  • checkout completion vs. identity-control coverage
  • model precision vs. real-time latency
  • shadow evidence vs. customer-facing change

Why Affirm

Interest-free plans depend on real-time decisions that protect consumers and merchants without losing the checkout moment.
