“It’s [a credit card] a way to pay for things that’s a loan, but it doesn’t have to be a loan if you pay it back on time but it can be a loan if you need money

“It’s [a credit card] a way to pay for things that’s a loan, but it doesn’t have to be a loan if you pay it back on time but it can be a loan if you need money in an emergency.” This seems overly pedantic. It’s still a loan regardless of whether one pays it back within the grace period. A better way to describe it is a 0% interest loan that escalates to a usurious rate once the grace period date is reached.
