Why a credit card can actually be a useful tool

Used carefully, a credit card combines convenience, flexibility and a bit of financial security — it can smooth out timing gaps between when you pay and when income arrives.

The key word is "carefully": a credit card is most useful when the balance is paid off in full each month, avoiding interest entirely. Carrying a balance long-term is where the cost adds up.

If you're considering one, look at the full terms — annual fees, the interest rate that applies if you don't pay in full, and any conditions attached to rewards or benefits.
