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).

Good point, another good example of substitution vs conversion.

Credit cards have to be a standard size or they won't fit into various machines 
and wallets. 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.

Very cool, too bad they can't make it slightly bigger and call it 50 cm2

A new ad has been released by Wells Fargo entitled "Revolutionary: The new 
Wells Fargo Active Cash Card."  It announces:  "48 square centimeters of 
earning potential."
