Important things i need to know about credit cards and how they work. (growing up in life and want to make sure i know everything, do not use plagiarism! will give out brainiest, if your answer is suitable.)

You get kind of a credit every time you buy something from the card issuer. that means you borrow money for the purchase you make from the card issuer with the promise to pay them at the end of the month (or whenever your contract tells you to). it's easy to switch credit cards and there are a lot of free contracts out there. better give your credit card number to someone you don't trust than your bank account number. cause in case of a fraud you can just change credit card. changing the bank account is a lot harder than changing credit card (plus the card issuer has the problem of not getting their money. not you)

To be honest, here's what i think. i think the answer is (and i'm not exactly sure), that it is, both personal and household income.
