Accepting TWINT in Switzerland

You do not contract with TWINT as a scheme in the usual sense. Acceptance runs through TWINT directly or through a PSP connected to it, with the customer authorising in their app by QR code or in-app confirmation. It is account-based, settles without card interchange, and carries no card-style chargeback.

The section above says what does not apply. This one says what to do about it, because the absence of a statute is not the absence of a right. It is a drafting question.

Inside the European Economic Area a merchant is handed several things without asking. Capped interchange on consumer cards. A ban on surcharging the instruments those caps cover. A right to steer customers towards a preferred instrument and to tell them what acceptance costs. A right to buy acquiring from any licensed provider anywhere in the area. Scheme and processing priced apart rather than as one figure. For every one of those, Switzerland is a third country.

So the Swiss agreement has to carry them as terms, or you do not have them. Ask for the interchange equivalent shown separately from scheme costs and from your provider’s markup. Ask for a notice period and a stated basis for any rate change. Ask for reporting per method and per card category rather than one Swiss line. And put in writing what you may and may not do at the checkout, because in Switzerland nothing else grants it. None of this is exotic. It is precisely the list a European contract never has to mention because a regulation already said it, which is exactly why it goes missing from a Swiss one.

Datatrans and Saferpay, both Swiss, and Checkout.com all document TWINT, among others, as do the other gateways serving Switzerland. The useful questions are what a TWINT transaction costs against your effective Swiss card rate, whether the line is visible separately, and whether your Swiss pricing was negotiated on Swiss volume or inherited from a European agreement.

What you pay is set in your PSP contract, not by the scheme. Start by establishing whether you are overpaying your PSP, or move straight to cutting your PSP costs, because a cheap method priced badly still costs more than it should.

How a wallet behaves inside your flow, from one-click through to the return after a challenge, is a checkout flow optimisation question as much as a pricing one.
