It's no longer a legal requirement to wear a face covering on public transport in England, Scotland or Wales. We do encourage you to wear a face covering in crowded spaces, if you can. For the latest travelling safely information for England, Wales and Scotland, see our Coronavirus page.
A contactless payment is where you simply tap your card on a reader to pay. You don't even need to enter your pin. You can tell if your debit or credit card has contactless if it's got the contactless symbol on the front.
New cards usually have contactless payment. But if you're unsure, just ask your card issuer to help you out.
