Contactless is wonderful, especially now the receipt for smaller items is effectively being phased out; couldn't the receipt-handling just get handed over to banks, ultimately? That could be really useful... I still use cash, probably more than the average. There are just a handful of situations - paying for a newspaper, or at my local bakery - where it feels more 'natural' to me to use cash, but I'm sure that feeling will go eventually!
