Worldline vs. Payrexx: POS terminal comparison for Swiss SMEs

Anyone looking for a card terminal in Switzerland will almost inevitably come across Worldline – the largest Swiss POS provider with a long-standing market dominance. But for SMEs, self-employed persons and mobile merchants, the question arises: Is Worldline with its Interchange++ model really the cheapest and simplest choice – or is it worth looking at newer alternatives with a transparent fixed-price model?

This guide compares Worldline and Payrexx in a concrete way for everyday Swiss POS life: fee structure, payment methods, onboarding and support – so that you know which provider suits your business.

1. The core problem: Interchange++ vs. Blended Pricing

The most important difference between Worldline and Payrexx is not the absolute fee level – but the predictability.

Worldline uses the Interchange++ model: You pay a Worldline service fee plus the interchange fee of the card network (Visa, Mastercard) plus any surcharges. The interchange varies according to card type, country of origin and merchant category. What a transaction ultimately costs depends on which card your customer pulls out.

Payrexx uses Blended Pricing: A fixed rate per payment method, regardless of the card type. Debit card POS always costs 0.95% + CHF 0.15 – regardless of whether it is a Swiss standard card or a premium debit card.

What Interchange++ means for SMEs in practice

The following table shows how Worldline fees are structured and why the final price is difficult to predict (as of: Worldline price sheet from February 2026):

For SMEs without a finance department, this means: The monthly Worldline invoice contains a list of surcharges resulting from the customer mix – and these can differ from month to month.

2. Fee comparison: What a transaction really costs

A direct comparison is difficult because Worldline does not publish final prices – the price sheet only shows the service fees, not the interchange share. The following table shows realistic estimates for typical Swiss SME scenarios (as of: May 2026):

* Worldline estimated values are based on the public price sheet (service fees) plus typical interchange guidelines of the card networks. Actual costs depend on the individual merchant contract.

Important: For foreign cards (tourists, business travelers), the Worldline surcharge of 0.98–1.30% has a significant impact. Payrexx has no separate international surcharge – the blended rate applies to all cards.

3. Payrexx POS fees in detail

Payrexx publishes its POS fees transparently and without footnotes (as of: May 2026):

POS terminals require at least the Standard plan (CHF 19/mth.). The terminal rental for Nexgo N6 and N86 is normally CHF 25/mth. and is currently free, while stocks last. Tap to Pay (Android smartphone as terminal) is included in all plans – even in the Free plan.

4. Online payments: One system vs. two contracts

For businesses that sell both in-store and online, the system architecture is crucial.

Worldline offers online payments via the Saferpay platform – an independent product with a separate contract and separate billing. Online transactions at Worldline cost 1.70% + CHF 0.19. Anyone who wants to combine POS and online must manage two separate systems.

With Payrexx, everything runs through one account: POS terminal, Tap to Pay, online shop integration, payment links and QR Pay. Transactions from all channels appear in the same Dashboard, and payouts are bundled into one IBAN. For SMEs using both channels, this significantly reduces administrative effort.

5. Onboarding: Individual offer vs. same-day

Worldline primarily targets larger merchants and companies. Onboarding runs through an individual offer – prices and conditions are negotiated, not communicated on a pricing page. For a hairdresser, food truck or yoga studio owner, this process is often disproportionately complex.

Payrexx communicates same-day onboarding: Submit documents by 16:00, and your account can be activated on the very same day. The terminal is delivered ready for operation. For seasonal businesses or start-ups wishing to get started quickly, this is a concrete advantage.

6. Support: 24/7 global vs. Swiss phone

Worldline communicates 24/7 support at a global level. This is useful for enterprise customers with complex integrations – for a practice or a market stall that is no longer contactable in the evening, this is less relevant.

Payrexx offers telephone support Monday to Friday from 9 am to 5 pm – with a Swiss team speaking German, French, and Italian. In addition, there is a ticket system with 24/5 availability. For Swiss SMEs who want to call in Swiss German when a problem arises, this is much closer to reality than a global support center.

7. Overall comparison: When is which provider worth it?

For whom Worldline remains useful

Worldline is the established market leader in the Swiss POS market – with an infrastructure designed for very high transaction volumes and complex enterprise integrations. If you have already invested in a Worldline ecosystem, have a very high volume with corporate or Swiss debit cards, or need a specific cash register system integration, you are in good hands with Worldline.

For whom Payrexx is the better choice

For Swiss SMEs, self-employed persons, associations and mobile merchants, Payrexx offers the simpler and more transparent model: fixed fees, online and POS from a single system, fast onboarding and Swiss support. Particularly with an international customer mix – tourists, conference participants, business travelers – the Blended Pricing model really pays off.
