Maestro is being retired: what merchants need to know

Maestro is on its way out. Mastercard stopped issuing Maestro-branded cards in Europe from 1 July 2023, and cards issued before that date continue to work only until they expire, which means 2027 at the latest. If Maestro still appears in your checkout or your terminal configuration, it is a shrinking share of a shrinking base.

Why Maestro is being replaced by Debit Mastercard

Maestro was designed in 1991 for the physical world. It was the first point of sale debit card usable internationally, and it was built before online shopping existed. That heritage is the problem: Maestro card numbers run to nineteen digits and many cards carry no CVV, which makes them awkward or impossible in card-not-present flows. Debit Mastercard resolves that by behaving like any other Mastercard, accepted wherever Mastercard is accepted, online and in store.

Terminals

What this means for your checkout and terminals

Acceptance of Debit Mastercard is not automatic on legacy configurations. Terminals and gateway settings built around Maestro may need updating, and the risk is an acceptance gap rather than a cost increase: a card presented that your setup does not recognise. Providers vary in how far ahead of this they are. Asking your acquirer to confirm Debit Mastercard readiness across every channel is a five-minute question with a conversion consequence.

Pricing

The pricing question nobody asks

Maestro and Debit Mastercard do not necessarily price the same way. A migration that happens silently in the card base can move volume from one rate to another without any change to your contract and without any notification. If your debit volume is material and you have not compared your effective rate before and after the migration, that comparison is worth running while there is still a before to compare against.

Reporting

The breakdown you are entitled to after every transaction

Article 12 of Regulation (EU) 2015/751 obliges the acquirer to provide the payee, after the execution of an individual card-based payment transaction, with the transaction reference, the amount in the currency of the payee’s account, and the amount of any charges, indicating separately the merchant service charge and the amount of the interchange fee.

It may be aggregated, but only on terms. With the payee’s prior and explicit agreement the information may be aggregated by brand, by application, by payment instrument category and by rate of interchange fee. Notice what even the aggregated version preserves: a split by brand and by category.

That is exactly the instrument a brand migration calls for. Volume moving from one debit brand to another shows up as a shift between brand lines. If your reporting only ever shows a single number, then either the aggregation you agreed to is coarser than the regulation describes, or nobody has asked for it. Both are fixable in one email.

Which markets are affected

The phase-out is Europe-focused, with Germany, Italy, the Netherlands, Belgium, Switzerland and Austria among the largest historic Maestro markets. Maestro continues in some non-European markets, so a merchant selling internationally may be running down Maestro in Europe while still accepting it elsewhere.

Acceptance

An unrecognised card is not a cost line, it is a lost order

The risk in a brand retirement is not that a rate goes up. It is that a card is presented and your configuration does not know what to do with it. That failure never appears in a payment cost report, because a transaction that did not happen has no cost.

Size it before deciding how urgent it is. On 200,000 debit transactions a year at an average order value of 45 euro, a 3 per cent share arriving on a card your estate does not accept is 6,000 transactions. If half of those customers do not retry on another method, that is 135,000 euro of revenue leaving without a trace. Put your own numbers in and the shape of the answer does not change.

The check is not a project. Ask your acquirer to confirm, per channel, that Debit Mastercard is accepted on every terminal profile, every gateway configuration and every stored-card flow you run. Then ask what happens today to a card your setup does not recognise. The second question is the one that produces the interesting answer.

Reviewing what card acceptance costs you

What you pay is set in your acquiring contract, not by the scheme. Start by establishing whether you are overpaying your PSP, or move straight to cutting your PSP costs, where interchange, scheme fees and markup are separated before anything is negotiated.
