UK's biggest supermarket Tesco is still to roll out 'apple pay' outside London, very strange, I go to Lidl now who do accept 'apple pay'.
Please do not use Apple Pay as a synonym for contactless, as it isn't even true. E.g. Tesco does accept contactless in London, but they do not accept Apple Pay for all cards (Visa/MC only, no Amex - but they DO take Amex contactless, they only refuse Amex Apple Pay - I think the reason is because Apple Pay goes online and their terminals don't have that ability for Amex contactless).
