Credit Cards

I haven't had a credit card for years as I just pay for stuff.

With interest rates now half-decent it makes sense to move some cash from the bank which pays sod all into an interest bearing account that pays a sensible rate.

If I do this there's a nagging concern that "something" might come up where even with an instant access savings account I can't get the funds transferred quickly enough so I had a quick check and I can get a credit card from my bank with around a £7K credit limit.

I don't really care about avios or rewards or anything like that so if I just wanted something for either daily purchases or expensive purchases where a credit card offers some protection or an unplanned expensive purchase is there much to be looking out for if the intention is it would always be paid off as soon as the bill lands?

All the comparison sites seem focused on people who need specific benefits like long 0% periods or rewards.

I just want something there that can be used like a debit card but gives a bit of time if the cash is in a savings account and a day away.

Sorted.

£9K limit and 10% APR.

Not that the APR should matter given my use case but it's remarkable how much difference there is between cards
