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 long-standing market dominance. But for SMEs, self-employed individuals, 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 specifically for everyday Swiss POS operations: fee structure, payment methods, onboarding, and support – so 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 level of fees – but 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 by 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 card type. Debit card POS always costs 0.95% + EUR 0.15 – 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 statement contains a list of surcharges resulting from the customer mix – and they can differ from month to month.

2. Fee Comparison: What a transaction actually costs

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

* Worldline estimates 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 (EUR 19/mo.). The terminal rental for Nexgo N6 and N86 is regularly EUR 25/mo. 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 through the Saferpay platform – an independent product with a separate contract and separate billing. Online transactions with Worldline cost 1.70% + EUR 0.19. Anyone wishing to combine POS and Online must manage two separate systems.

With Payrexx, everything runs through a single 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 to one IBAN. For SMEs using both channels, this significantly reduces administrative effort.

5. Onboarding: Customized Offer vs. Same Day

Worldline is primarily aimed at larger merchants and companies. Onboarding takes place via an individual quote – 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 promises same-day onboarding: If documents are submitted by 4:00 PM, the account can be activated on the very same day. The terminal is delivered ready for operation. This is a clear advantage for seasonal businesses or start-ups wishing to get started quickly.

6. Support: 24/7 Global vs. Swiss Telephone Support

Worldline advertises 24/7 support at a global level. This makes sense for enterprise clients with complex integrations – but for a practice or market stall that is closed in the evening, this is less relevant.

Payrexx offers telephone support Monday to Friday from 9 AM to 5 PM – with a Swiss-based team speaking German, French, and Italian. This is complemented by a ticket system with 24/5 availability. For Swiss SMEs that want to call and speak in Swiss German if a problem occurs, this is closer to their daily reality than a global support center.

7. Overall Comparison: Which provider is worth it and when?

For whom Worldline remains useful

Worldline is the established market leader in the Swiss POS market – with an infrastructure built for very high transaction volumes and complex enterprise integrations. Those who have already invested in a Worldline ecosystem, have a very high volume of predominantly Swiss debit cards, or require a specific POS system integration, are in good hands with Worldline.

For whom Payrexx is the better choice

For Swiss SMEs, self-employed individuals, 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. Especially with an international customer mix – tourists, conference participants, business travelers – the blended pricing model pays off concretely.
