Today more banks around the UK have announced that they are going to begin supporting Apple Pay. Those banks are Hailfax, Lloyds, Bank of Scotland, and M&S Bank. If you have a credit card with one of those banks you can add them to Apple Pay and purchase items with the iPhone’s NFC.
The UK was Apple’s second country to get Apple Pay, after the US. You can buy tons of items without your credit card in quite a few stores as well. Apple Pay also allows you to purchase items inside of an app without needing your card with you.
