Why does it ask me to verify my payment details?

[iMore Question]

Hi when I try and download a new app or update an old one it takes me to my card details and no matter how many times I put it in it won't accept it even tho I've used the same card forever!

If there's no money on it, it won't work. I had to recently switch cards
