Square Terminal vs Stripe Reader S700: Which UK Card Machine Wins in 2026?

Two strong all-in-one terminals serving very different buyers. Square Terminal is plug-and-play retail and hospitality hardware with a strong ecosystem and a flat 1.75% UK rate. Stripe Reader S700 is the in-person counterpart to Stripe online, sitting inside the Stripe Terminal SDK and best operated by a team that has Stripe developer time. Square wins for off-the-shelf SMB. Stripe wins for hybrid online + in-person merchants already on Stripe.
