Instant approval credit cards help you save time and are very convenient because you don’t have to wait for weeks for the card issuer to let you know of your application status. Some online approval cards let you know of their response within 60 seconds. Talk about fast! If a card issuer rejects your application, you have the choice and flexibility to apply with another card issuer.

Although with these cards you will receive an answer instantly, such as through the “Express Approval” system provided by American Express (NYSE:AXP) cards that give you an answer within 60 seconds, you will still have to wait from 5-7 business days to receive your card in the mail if you are approved.

I recommend that you don’t apply for more than 2 or 3 cards each time, since excessive applications can negatively affect your credit score. You should also make sure you know your FICO score, since most issuers make their decisions based on that, and if you don’t have excellent credit you might not receive such a quick instant approval.

Here is a list of the best instant approval credit cards so that you can compare, choose and receive an almost immediate answer once you apply for the one that you think is best for you, and know if you have been accepted or not.
