Prefer process controls from agent spend controls and human-in-the-loop payments before hardware.

Principles

Ops security kit
  1. Hardware second. Policies, allowlists, and dual control beat a lonely security key.
  2. One search, one product intent.
  3. No “crypto hardware wallet” spam unless your threat model actually needs offline keys for custody—most agentic checkout work does not.

Network hygiene (optional)

Most agent payment security is still policy + logs + dual control, not a new router.

Recommended kit by role

Approval operator (human-in-the-loop)

  1. FIDO2 key (plus backup)
  2. Privacy screen if public desk
  3. Notebook for offline exception notes

See Human-in-the-loop payments.

Merchant / integration lead

  1. FIDO2 on admin accounts
  2. Cable lock for shared office
  3. Shredder for printed onboarding docs

See Merchant agentic readiness.

What this kit is not

  • Not a product ranking of banks or PSPs. See provider comparison and Stripe / OpenAI agentic commerce.
  • Not investment or legal advice. Operational hygiene only.
  • Not a reason to delay dual control. Two people with policy beats one person with a fancy key.
  • Not a single Amazon mega-search from the homepage. Multi-keyword dumps land wrong; each row above is one intent.

Operator checklist (weekly)

  1. Confirm backup FIDO2 still enrolled.
  2. Review allowlists and spend caps (spend controls).
  3. Shred printed secrets older than the retention policy.
  4. Walk one human-approval path end-to-end (HITL).
  5. Re-read refunds and agent responsibility when product owners push “fully autonomous checkout.”
