Case Study: Shopwave achieves rapid Terminal API integration for UK contactless payments with Square

Shopwave - Customer Case Study

Shopwave is a global, customizable POS platform for large retail brands and quick‑service restaurants, founded to solve widespread frustration with legacy POS systems. The company needed a reliable payments partner that matched its brand and would enable UK merchants to accept contactless and card payments—functionality that wasn’t possible with Square’s U.S.-only Reader SDK.

Shopwave chose Square for its uptime, fast payouts, and responsive support, joined the Terminal API early, and built the integration in a couple of days using clear docs and Developer Support. The Terminal rollout with London food truck Rainbo unlocked contactless and broader card acceptance, impressed customers, and set the stage for scaling the integration to more UK businesses.
