300625 Customer Data Retention

We have a PPC search engine and when the user goes back in after creating an account and wants to deposit more funds, they have to refilll in all of the information including their credit card. We want it where they create their account and can click/check a box and each time they log in to put in more funds, all of their information pulls up and they can just type in the dollar amount wanting to add and click enter and it processes without them having to put the name, address, cc number etc...in each time.
