Prepaid Cards, Partial Approvals and Honor All Cards

There's no prepaid-specific acceptance rule for merchants. If you went looking for one, that's why you couldn't find it. What governs whether you have to take a prepaid card is the Honor All Cards rule, and what governs whether a prepaid card with a small balance declines or partially approves is a separate service your acquirer is obliged to support.

Those two rules together are the real answer, so here they are.

Honor All Cards, and what it binds#

The baseline is short. A merchant must accept all cards properly presented for payment, based on the technology the merchant supports (ID# 0008591).

Then the rule gets specific about what you can't do. A merchant may not refuse to accept a Visa product that is properly presented, and the examples given are a foreign-issued card and a card co-branded with a competitor's mark. Neither of those is a reason to decline.

Limited acceptance is permitted in a short list of cases: outlets deploying contactless-only acceptance devices, merchants accepting only Mobile Push Payment transactions, certain categories of Visa products for domestically issued cards in the AP Region (Australia), Canada and the US, and certain product categories for EEA and UK merchants.

That third one is the door a US merchant walks through, and it's narrower than it sounds.

The US version is about your category of acceptance#

In the US Region, a merchant that wishes to accept Visa cards must accept any valid Visa card in its category of acceptance that a cardholder properly presents (ID# 0002867).

So you choose a category. Within it, you take everything. You don't get to accept some debit products and refuse others, and prepaid sits inside the debit category rather than forming a category of its own. That's the reason no prepaid-specific acceptance rule exists: prepaid isn't a separate acceptance decision.

The same rule adds that you must let the cardholder choose whether to pay with that Visa card or with another means of payment you accept. The choice is theirs, not the checkout's.

Steering is allowed, denying choice isn't#

There's a line worth quoting because people get it backwards in both directions. A merchant may attempt to steer customers who initially present a Visa card to an alternative payment method, but may not do so in a manner that denies consumer choice. The US section puts it more plainly still: the merchant may request or encourage a cardholder to use a means of payment other than a Visa card.

So asking is fine. Offering a discount for another method is a pricing decision, not a rule violation. What you can't do is make the Visa option unavailable or unusable once they've chosen it.

The rule also preserves a risk judgment. A merchant may consider whether present circumstances create undue risk, and the example given is a high-value electronics sale where the card's signature panel is unsigned and the cardholder has no other identification. That's a narrow allowance for a specific situation, not a general licence to decline card types you don't like.

Partial authorization is the actual prepaid fix#

Here's the mechanism most merchants don't know they can turn on. When a prepaid card doesn't hold enough balance for the full amount, the choice isn't decline or nothing. Partial authorization returns an approval for the available balance, and the customer covers the rest another way.

This is where prepaid cards genuinely touch a card-absent checkout, and it's a conversion question rather than a compliance one. A declined sale on a gift card with eleven dollars left is a sale you could have had.

Who has to support it, and who chooses to#

The obligations split cleanly, and the US answer is narrow (ID# 0031005).

Merchants required to support it. In the US Region, MCC 5542, automated fuel dispensers. That's the whole US list. Europe requires the same single MCC. The LAC Region requires a long list covering taxis, grocery, convenience stores, service stations, EV charging, restaurants, fast food, pharmacies and miscellaneous retail, for debit and prepaid cards.

Everyone else. Optional. You participate if you choose to.

Your acquirer. Not optional. An acquirer and its VisaNet processor must participate in the Partial Authorization Service to support merchants that choose to participate. An acquirer must also participate at minimum by supporting the merchant categories Visa specifies.

Read those together and the practical position is clear. If you're a US ecommerce merchant outside MCC 5542, partial authorization is a switch you can ask for, and your acquirer is required to be able to give it to you. "We don't support that" isn't a rules-compliant answer from an acquirer, though it may well be an accurate description of a gateway integration that nobody has built.

What to actually do#

• Ask your acquirer whether partial authorization is enabled on your MID. Not whether they support it, whether it's on for you.
• Check what your checkout does with a partial approval. An approval for less than the requested amount needs handling. A cart that treats it as a failure is worse than not having the service.
• Stop trying to filter card types. Inside your category of acceptance you can't, and prepaid isn't a separate category.
• Steer if you want to, but keep the choice real. Encouraging another method is permitted. Removing the option after the customer picked Visa isn't.
• Remember prepaid shows up in refunds too. A discarded prepaid card is one of the listed conditions that lets you refund by alternate means, and prepaid cards with cash access sit in the quasi-cash definition.
