So I know there have been numerous posts about storing credit card information. We are building a mobile application and want people to be able to enter in their card information once, not with each purchase.
We looked at Authorize.net CIM, and it appears to be an ideal solution (we just store a profile ID or Token that returns the credit card number)… but it might fall short of our needs, since the credit card information isn't processed (necessarily) by authorize.net but by whatever merchant account we are sending the payment too. In other words we want to store the credit card information like a wallet… not necessarily process with Authorize.net every time.
Reading the CIM XML documentation (p.94), it looks like the getCustomerPaymentProfileResponse masks the credit card return data… so I don't see how that would be useful for processing if the data is masked?
We do have some other options for implementation but I was really hoping to have a web-based way for customers to manage their payment accounts. Does anyone know of any ways to store credit card data that can be called on demand to be passed to any given merchant's processor?
EDIT 4.28.2011 – I'm hitting a wall with this. What if we don't store the credit card information at all, have customers enter it and then pass it… how do we do that securely? No storing it, pass along HTTPS, encrypt card data while in transit?

Sadly, there is no easy way to achieve this.
As you are aware, Payment Service Providers will securely store the card details, and return a token id (so that you can reference those details), but they can never return the original card details back to you.
This is because the PSP will have gone through PCI-DSS compliance. Part of that compliance is ensuring that anywhere the card details are passed (such as to other 3rd parties) is also PCI-DSS compliant. If they were to allow card details to be returned from the vault to the client, then they would need to ensure that the client is also PCI-DSS compliant (which would pretty much defeat the point of the client using a Payment Service Provider!).
Your options therefore are:
- Work through PCI-DSS compliance so that you can store the card details securely yourself.
- Store the card details to every Payment Service Provider that you interoperate with, and store the returned tokens from each.
