Agent payments are really an identity and liability problem, not checkout

Agent payments are less a checkout problem than an identity and liability problem.
- Card access is the easy part; the hard part is deciding who owns chargeback liability when an agent buys the wrong thing repeatedly.
- Fraud systems will flag agent-like behavior — no device history, datacenter IP, late-night repeated purchases — because it looks the same as stolen-card abuse.
- The seller side is even messier: an agent has no legal existence, no bank account, no merchant agreement, and no tax signer.
- The likely primitive is scoped, revocable, budget-capped credentials, similar to OAuth scopes.
- The author, who works on payments infrastructure, asks whether agents will just keep using their owner’s card or whether card networks will build the missing layer themselves.
