Honor-All-Cards Rule and Acceptance Tiers

Also called honor all cards, acceptance tiers, tier declining

The network rule requiring you to accept every card of a brand, which the preliminary 2026 settlement would replace with three declinable tiers.

What it is

Honor-all-cards is the network rule that if you accept a brand, you accept all of that brand's cards. In practice it means a merchant who takes Visa credit cannot refuse the premium rewards card that costs substantially more in interchange while accepting the basic consumer card that costs less. The rule is the reason a merchant's effective rate rises when their customer mix shifts toward rewards cards, without anything about the merchant changing. The rule has been a central target of merchant litigation for two decades, because it prevents the most obvious form of cost management: declining the expensive product. Under the Rule 23(b)(2) settlement that received preliminary approval in June 2026, honor-all-cards would be replaced with three acceptance tiers: standard consumer, premium consumer, and commercial. A merchant could decline an entire tier, but would have to accept all cards within any tier it does accept. That change is not in effect. The settlement has preliminary approval only and is under objection, with a threatened appeal to the Second Circuit. Any implementation would follow final approval, with rule changes reported to begin within 60 days of approval.

Why it matters to your business

This is the reason your effective rate can rise without your rates changing. If your customer base shifts toward premium rewards cards, and in a seasonal affluent market like Southwest Florida it does, your cost per dollar rises and nobody sent you a notice. Do not let anyone sell you tier declining today. It is not live, and for most small businesses it would not be advisable even once it is. What you can do now is measure your card mix, so that when acceptance tiers become real you can make the decision on your own numbers rather than on a sales pitch. This is education, not legal advice. The acceptance tier changes are part of a settlement with preliminary approval only.

Where it gets contested

Merchant groups have argued for twenty years that honor-all-cards is the mechanism that lets networks upsell issuers into premium products whose costs merchants must absorb without consent. The networks respond that universal acceptance is the product cardholders buy and that a card which might be declined is worth less to everyone, including merchants who benefit from confident spending. The acceptance tier compromise satisfies neither camp fully. Large merchants with the leverage to decline a tier gain a real negotiating instrument. Small merchants mostly do not, because premium consumer cards represent a large share of card-present spend, and declining them at a Naples restaurant or a Fort Myers marina would be commercially self-defeating. What remains unresolved is practical: nobody knows how tier declining would be implemented at the terminal, how customers would be told, or how the resulting friction would be absorbed. Those details arrive after final approval, if it comes.

How to check it yourself

Ask your processor for an interchange detail report showing your volume by card product for a month. That report tells you what proportion of your volume is premium consumer, and it is the only basis on which any future tier decision could be made intelligently.
