Sage Pay
Sage Pay is a UK payment processing service (formerly known as ProtX). In short, they handle the credit/debit card collection and authorisation process on behalf on online businesses.
SagePay is used by many shops I’ve built and they provide a reliable service with realistic fees. They’re usually top of my list when customers ask for a recommendation. An additional benefit is that they’re developer-friendly (good integration guides and test environment).
