I want to apply for a capital one credit card. If I simply apply and I get accepted will they send me a card? I don't want to get charged anything. Also, if i get accepted and I want the card will i get charged anything if I don't use it monthly but just keep it for emergencies?

Upon acceptance, the credit card company will send you a card, yes. I am not aware of any Capital One accounts that are charged an annual usage fee, so you will not be charged anything upon acceptance. (Read the fine print on the application to be sure.) Similarly, you will not be charged a service charge each month if you make no purchases with the card. (Again, read the fine print on the application to be sure.)
