I guess there is a daily limit for contactless? Not being funny but £30 goes a bit further down here than in London ie. more than a coffee so if you do steal a card, head this way!. Anyway, that's not the point. I have used my Santander Debit card hundreds of times without having to enter a pin. But I suppose if I used it 5 times in a day I might be asked? Is that how it works?
Whatever, I still think the fingerprint is the way forward. As I said, if Apple Pay was in most places, I would ask for chip and pin cards again.
