Hello,

I am coding a new OnlineStore (the existing ones fit not my needs, are
to complicate to use or simply closed source and too expensive e.g.
InterShop) with an integrated powerful ledger.

So now it comes to infos about Credit Cards, PayPal and friends...

Does someone have an experience with it

1) how I should store it
2) how the TABLE fields should look like

And yes, I would use a reference to external tables instead of puting
those data in the main "customer" TABLE...

Thanks, Greetings and nice Day/Evening
