Sometimes people get (understandably) confused as to where their credit cards are accepted, especially if those cards come from retail stores or they have funky designs that make it hard to see what type of bank card they actually have. Below we offer a long list of credit cards, with a few words about whether they can be used just about everywhere or whether they are confined to a certain store chain. (Note that Mastercard and Visa are accepted just about everywhere, while American Express and Discover have a somewhat more limited acceptance, but can still be used widely.) If you have questions or corrections to suggest, leave them in the comments at the bottom of the page.
