A large French payments processor that absorbed SIX Payment Services in 2018 and became the incumbent for Swiss card terminals. It offers in-store terminals, Tap on Mobile on an ordinary phone, and the Saferpay online gateway — and it supports the full Swiss payment mix, PostFinance Pay included. When Worldline is the better choice: You need PostFinance Pay. Worldline is the only one of the three that supports it, and if you need it the comparison ends there. Tap on Mobile suits you: 1.7% flat, no fixed monthly cost, and it takes TWINT. For a small merchant who doesn't need a catalogue, that is a genuinely competitive offer. You have real volume and want negotiated rates with dedicated account management. You want an established Swiss acquiring relationship with formal contract terms. When Gwinn fits better: You want your products in the register. Tap on Mobile is a payment app — you type in an amount every time, or buy and integrate separate POS software. You want an online shop, not a checkout to bolt onto a site you commission. Saferpay is a gateway, not a store. You're one person or a small studio, and a multi-year terminal contract is overkill. You want to be selling this weekend rather than after a sales process. Your catalogue and TWINT on one screen — traditionally: One or the other: a POS app that can't take TWINT, or a TWINT app with no catalogue in it; with Gwinn: Both, on one screen — tap the photo, then choose TWINT, card or cash. What a sale costs — traditionally: Their rate, all in — and at a stall, every one of them beats ours on cards; with Gwinn: Your processor's rate, plus 0% from us in person and 1% online on Free — so take TWINT, which is on the same screen. Building the store — traditionally: A developer, weeks in a builder, or no online store at all; with Gwinn: AI drafts, writes and photographs it in an afternoon. Inventory — traditionally: Rigid grids you maintain by hand; with Gwinn: Scan your notebook; the AI keeps it. Pricing — traditionally: A monthly fee, a higher per-sale rate, or a negotiated contract; with Gwinn: Free in person. 1% online, or flat CHF 25. Your money — traditionally: Held, then paid out; with Gwinn: Straight into your own Stripe. Where your data lives — traditionally: Whichever cloud regions they use — check their sub-processor list; with Gwinn: Europe, mostly Germany — servers we rent from Hetzner.
