Android Pay, like Apple Pay, lets you use your phone to pay for items like you would with a contactless card. Businesses can also embed Android Pay functionality into apps and websites (via Chrome), ensuring that you don't have to manually type in their card details. Signing up to Android Pay also grants you access to Android Pay Day, which offers discounts every month on the Tuesday before your next pay slip. Starbucks and Deliveroo have both offered deals, but there hasn't been much activity since its launch in June.
