It is not rocket science; it is just applying for a credit card 
But I have seen people break into a sweat when they want to get a new credit card.
First of all there is the selection of the card. Oh! Which card am I going to get? Then there is the matter of optionally submitting some documentation and private information. With the entire hullabaloo about privacy, that seems like a scare right there.
But the biggest problem is that one is never clear about the charges that the credit card company can and will levy on you. There is actually legislation and regulation in place to simplify the credit card charges. Unfortunately that has not lowered the problem of the consumers to a reasonable level.
So, I think that you need to visit a website that takes the mystery and guesswork out of a card. Only then can you apply for a credit card with ease.
