This is the scenario I expect the system behave:
I have a platform where users can register and store their credit card information online, and with specific user's action, system automatically settles payment. Of course, user expect automatic payment system as we said so when they enter their card information, and the purpose of this is to simplify the process when they decided to pay for something.
My question is this:
I found that Amazon saves user's card information when they purchased some products then user doesn't need to put all the card information again but just select from the list of cards he used and with one click, it finishes payment. Also, in price line, I found that it automatically settles after bid accepted.
So I tried to find the provider or payment gateway company that Priceline or Amazon provide, and tried to find the way to implement the system at least, but couldn't find any. What I have found so far were like, using paypal, and it requires user to have paypal id
I'm doing this in PHP, can anybody give me some clue please?
Thanks in advance.
