Hello I'm doing a project for school and I was wondering if someone here could tell me when were credit cards invented? And then if anyone could tell me who invented credit cards that would be super helpful too! What I have found so far says the that the first credit card was issued by Flatbush National Bank in Brooklyn New York in 1946 and the name of the inventor was John Biggens but it was only used locally. Then the first real credit card was issued by Diners Club in 1950 and that was who issued the first credit card.
Can anyone tell me if this is all accurate because I have so far seen conflicting stuff about it on the net.
