I don’t use debit cards. I’ve had an account pretty much frozen after a cardreader was used to hit a checking account. Every purchase is made with a rewards credit card.
And yes, I write down all transactions (ACH payments for credit cards, automatic payments, the occasional check, plus deposits etc) in a check register. I add or subtract each one when it happens and confirm with the bank every two weeks or so.
And I can tell you, this can be pretty darn handy when trying to hunt down an old purchase or something. It’s at least as much history/record-keeping as it is the + and -.
