SPENDING & ACCEPTANCE • MERCHANT RISK
No 100% acceptance guarantee — what to tell end usersCard acceptance depends on whether the merchant supports prepaid cards, not on Swype. Here's the known-inconsistent merchant list and why, so you can set expectations correctly. |

KNOWN ISSUES 7 merchant types |
Summary: no 100% acceptance guarantee can be provided for any merchant. Acceptance depends on whether that specific merchant supports prepaid cards. A defined set of merchants and use cases is known to be inconsistent — don't commit to acceptance at these in your own product copy or support scripting.

The known-inconsistent merchant list |
These merchants and use cases are known to be inconsistent and are explicitly not guaranteed:

Travel & estimated-amount bookings

Why the travel category fails specifically |
Hotels, car rentals, and similar merchants authorize transactions where the final amount is unknown at booking time. Per the Card Program Terms, this triggers a specific mechanic your end users will run into:
| ● | A hold is placed for an amount equal to or exceeding the final transaction value, not just the quoted price |
| ● | Held funds are unavailable for other spend until the merchant sends the final transaction amount |
| ● | Once the final amount is received, releasing the hold can take up to 7 days |
| ● | A booking can decline even with sufficient balance for the listed price, if the available Sub-Account balance can't also cover the inflated hold |
| ③ |
A related gotcha: unattended terminals |
Separately, virtual cards cannot be used at vending machines, kiosks, or gas station pumps at all. A physical card may also be declined "pay at the pump" even with sufficient funds — in that case, paying inside with the cashier is the workaround, since the pre-authorization amounts differ between the two flows.
|
Important Don't position Swype cards as guaranteed to work for any specific merchant in your own marketing or onboarding copy — including ones not on this list. New inconsistent merchants surface over time; treat this as a known-issues reference, not an exhaustive one. |
