I checked the specification for the dimensions of a credit card on Wikipedia (https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2FISO%2FIEC_7810&data=04%7C01%7Cusma%40lists.colostate.edu%7Caaa7bf19be654572ed7008d9534de929%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637632416354928756%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=AGhPs01YDTvR2jN%2Bo3P3fqiNh%2FSHPh06rd6zRCGcViU%3D&reserved=0). The actual article is a little muddled – the writers could not decide whether the length of the card was 3 3/8 inches or 3.4 inches. The length in SI was given as 85.60 mm. The use of decimal fractions and vulgar fractions is clearly a mess.
However using the values given in Wikipedia, the area of the card is 46.2 cm^2 (ignoring any adjustment for the rounded corners).

I measured a few, and they averaged 85.52 mm by 54.20 mm, with a width times height area of 4635 mm². That's less than the 4800 mm² claimed by Wells Fargo, and my measurement doesn't take the rounded corners into account, which reduces the area further. It sounds like they may already be exaggerating the size of their credit card.
