Accepting UnionPay as a merchant

UnionPay is the card network of China and, by transaction count, the largest in the world. For a European or Australian merchant the relevance is rarely domestic. It is inbound: Chinese travellers, students and cross-border shoppers who carry a UnionPay card and no alternative that works.

Acquiring

How to accept UnionPay as a merchant

You do not contract with UnionPay. Acceptance is enabled through your acquirer or PSP, usually as an additional network on an existing card integration rather than as a new method. Because the volume is concentrated in specific customer segments, the commercial question is not whether to enable it but whether the volume justifies the terms you were given when it was switched on, often without a negotiation.

UnionPay acquiring and PSP support

Support is broad among acquirers serving international commerce, so it is not a differentiator. What differs is pricing. UnionPay volume frequently sits outside the main negotiated rate card, priced as an exception, and exceptions are where margin hides. If UnionPay is a meaningful part of your inbound revenue and you cannot see its effective rate as a separate line, it is not being managed.

Cross-border economics and currency

UnionPay transactions from Chinese-issued cards are cross-border by definition, which brings foreign exchange and cross-border assessments into the price alongside the acquiring fee. Whether your customer is billed in your currency or theirs changes both the conversion rate applied and who earns the spread. That decision is a commercial one and it is usually made by default at integration rather than deliberately.

Presentment

Presenting the price in one currency or two

The section above says that decision is usually made by default. Here is what making it deliberately looks like.

There are two arrangements. In the first you present and settle in your own currency, and the cardholder’s issuer converts, applying its own rate and its own margin. You see a clean price, the customer sees a number they could not have predicted, and none of the conversion margin is yours. In the second you present the price in the customer’s currency at checkout, your provider converts, and the spread is shared between your provider and you on terms that are negotiable and almost never negotiated.

Three questions settle it. What conversion rate is applied and against which reference, what margin sits on top of it, and what share of that margin comes back to you. Then one more that is easy to forget: what the customer sees at the moment of paying. A Chinese customer looking at a price in euros is estimating. A Chinese customer looking at a price in renminbi is deciding. On inbound traffic that difference shows up in completed orders rather than in the fee line, which is why the currency question is a conversion question wearing a cost question’s clothes.

Which payment provider supports UnionPay for merchants in Europe?

Sipay, Rapyd and Global Payments all name UnionPay among the brands they accept, as do most of the major acquirers, which makes the question of support far less useful than the question of price. Ask what the effective rate on UnionPay volume is, whether cross-border and FX components are shown separately, and how authorisation rates on that traffic compare to your card average. Inbound international traffic often authorises worse, and a poor authorisation rate on a small volume can still cost more than the fee does.

Cross-border

The part of the price that is not the rate

On cross-border card volume the acquiring rate is one of three numbers, and it is frequently the smallest. Take 3 million euros of inbound UnionPay revenue a year and follow all three.

The acquiring rate first. At an exception rate of 2.9 per cent it costs 87,000 euros. Priced against a negotiated international rate of 2.1 per cent it costs 63,000 euros, so the exception is worth 24,000 euros a year on EBITDA, and it appears on your statement as a single line you have probably never questioned. Then the currency component, which is not in that rate at all. A conversion margin of, say, 1.5 per cent on the same volume moves a further 45,000 euros, before cross-border assessments, which sit on top of both. Whether any of that conversion margin comes back to you is a matter of how the arrangement was set up rather than of arithmetic.

So 24,000 euros in the rate and 45,000 euros in the spread are both negotiable, and only the first is ever discussed. Ask for the three components shown separately for a single month: acquiring, cross-border assessment, and conversion margin with the reference rate it was struck against. If your provider cannot produce that view, the number you have been managing is not the number you are paying.

Australia

Australia: surcharging ends on 1 October 2026

If you sell in Australia this matters. The Reserve Bank of Australia’s March 2026 Conclusions Paper removes surcharging on the designated networks from 1 October 2026, and UnionPay has confirmed it supports the reforms and is working to remove surcharging from the same date. For merchants who have been recovering the cost of international cards through a surcharge, that recovery ends and the cost moves to margin.

Reviewing what UnionPay costs you

What you pay is set in your acquiring contract, not by the network. Exception-priced volume is exactly the kind of line that never gets revisited. 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.
