You've really got me thinking now, maybe I'm being totally daft. Do you get paid into account A and then do your shopping from account B, and transfer between the 2 as and when you need the funds?
Yes. My "main" current account has a few thousand in, and is where my wages go in and standing orders/direct debits come out from. The debit card never leaves the house.
I go out with 2 cards.
One a credit card for supermarkets, clothes shops, petrol, DIY shops etc, for bigger purchases and which isn't contactless, so needs a PIN and I only use it in reputable places where I can see the till prices etc. I earn points on it and pay it off in full monthly so costs me nothing and I get protection if a firm goes bankrupt or refuses to refund faulty goods where the cost is over £100.
The other is a debit card with a different bank (Monzo) for small purchases on contactless which I use for street markets, takeaways, small shops with cheap card readers, bars, etc. There's never more than £50 on it and I top it up when I've spent a bit to get it back to £50. I get notifications pinged to my mobile when I use it, almost instantaneously, it usually pings whilst I'm still at the counter, so I can see immediately what they've charged if they're using a hand held without a screen or where the numbers are too small (I don't always have my reading glasses out).
Works well overall, just have to get into the habit of choosing the right card out of the two. The Monzo app shows your balance so prompts you to do a transfer if it's getting low.
