Some people who are signing up for a credit card these days want it to be instant, but before you have that kind of thinking in mind make sure you reach all the necessary requirements. To obtain any kind of credit card there are guidelines which are to be met and this applies for every particular card company.
The first thing to have is a great credit rating as if your credit rating is less than 750 then you will not get a credit card from some companies so easy. And in some cases you will be approved but you will have to wait first. If you have no debt you will be easily accepted but if you have about 8 credit cards and a lot of debt then they may run a serious background check on you. And if you have not had a credit score for a long period of time they will also want to check into your records to see what's going on. The first place to look for an instant approval debit card is on the internet, and some of them will tell you that you can get approved with a few seconds.
This is there regular statement as they know people are going to apply. If you are looking and you don't see an instant approval sign somewhere then you might not get approved. The other source would have to be the bank, no matter the kind of bank you have joined just go to any branch and ask them what kind of cards they offer.
