A while back, I posted a blog entry here on how many credit card numbers are available for American Express, Visa and MasterCard. I was quite excited when someone actually used my contact page to send me an email about it a few days ago. The person sent me the following link to his own entry with additional information on credit cards.
The number of credit cards held by Americans, 609,800,000, is very small compared to the quadrillion and one hundred trillion available numbers for the three card companies I just mentioned–remember, there are even more numbers available when we factor in other companies such as Capital One and Discover.
The infographics on Sean’s entry are quite startling. Take a look for yourself!
