Still trying to pay it off I bet. :D
"The general-purpose credit card was born in 1966, when the Bank of America established the BankAmerica Service Corporation that franchised the BankAmericard brand (later to be known as Visa) to banks nationwide," Sienkiewicz writes."
I've used credit cards over my adult life time and actually paid interest in the earlier years but it's been many years since I've paid a dime in interest. my current c.c. has a balance of about $2500, by the end of the credit cycle, it will be around $4,000, which I will pay in full. $4,000 is about my usual monthly balance, on which I get a 01.5% cash rebate or about $60 per month. I cash in just before Christmas time for an extra $700-$800 Christmas cash.
I have no idea what any of my cards charge in inrterest nor do I care, I don't pay it, whatever it is.
