I no longer use cash or notes, I use my credit card on "contactless", even when buying a newspaper, that way you are not touching anything that could be contaminated (apart from possibly the newspaper)!!

I also use contact less cards. Also they are so convenient. Well done Norman, another one joins the discussion

Hi extracted this from an article on Money, about the new polymer notes

The new notes will be more dirt-resistant than paper because they will be coated in a film so they can wiped clean, as well as being harder to fake because they contain features including a transparent window.
