The Swiss PSP market is mature and moderately concentrated: traditional banks plus SIX-operated infrastructure, with merchant acquiring dominated by Worldline (formerly SIX Payment Services / PAYONE) and Nexi as the principal alternative, plus SumUp and facilitators (Payrexx, Datatrans, Stripe) for smaller merchants. Domestic mobile payment is dominated by TWINT (bank/PostFinance-owned, ~6m users, ~64% of mobile-payment transactions), which merged with Paymit in 2016 to form a national champion. Mobile payments have overtaken debit cards and cash as the most-used method (~30.7% of transactions per the 2025 Swiss Payment Monitor). The Swiss fintech market comprised ~500 companies at end-2024, predominantly B2B.
The most distinctive structural signal is the domestic mobile rail. TWINT, backed by Switzerland's major banks and PostFinance, surpassed 6 million active users by 2025, accounts for around 64% of all mobile payment transactions, and processed over 901 million transactions in 2025. Mobile payment has overtaken debit cards (24.4%) and cash (24.2%) with a 30.7% share of all transactions per the Swiss Payment Monitor 2025, making it the most-used method. Any merchant entering Switzerland must support TWINT, and its bank-ownership structure shapes competitive access — feeding directly into the W7 COMCO competition picture.
Outlook
The acquiring structure is stable, while the mobile rail is the dynamic to watch given TWINT's dominance and the competition remedy attached to its NFC access dispute.
