Contain firmware-driven terminal authorization reversals
A payment can appear authorized while the in-person flow still fails to complete.
Device consistency, issuer timing, and merchant continuity can reveal different versions of the same problem.
“The reader says approved, then the sale disappears and staff don’t know what to tell people.”

What pulls against what
- merchant continuity vs. rollout speed
- firmware correction vs. service compatibility
- issuer variance vs. controllable timing
What is at stake
A firmware rollout is creating completed-looking in-person transactions that later reverse. The team needs a cross-system fix before more devices update
Why Stripe
At Stripe, this often matters because in-person payment reliability depends on both hardware and networked services.
