They won't be the only ones. A lot of shops now prefer cards to cash due to the virus, although not everyone is refusing them outright. It is a lot easier, quicker and more hygienic to simply tap your card on the reader than to handle cash and to have to give change. From 1 April the amount you can tap on a contactless card without having to use a PIN has increased from £30 to £45 so make use of it!
