If you were  Registered and logged in, you could reply and use other advanced thread options
I'll echo Roger's comments. Aside from asking for product advice, it maybe
worthwhile to review your architecture/goals.

Storing credit card information implies that it will be retrieved for future
use. Aside from normal retail operations like allowing customers to "save"
payment information for a quicker checkout process on a subsequent sale,
either by themselves online, or via telephone with a rep, the only other
probable use is for some data mining - but I don't think you need the entire
number to run reports based on credit cards.

On a large scale, say you have multiple "local" locations that run their own
localized sales/ops and then "batch" data into a central location (my guess
for your FTP need), the question still remains, what is the purpose for
including credit card information in such a batching process? I'll assume
this is just to allow the scenario I mentioned - allowing customers
easier/faster experience on a subsequent sale, they may have bought an item
from Store A in CA, but can still have the same ease if they ordered through
your web site or call center in NY or anywhere. In this case, the question
which Roger already asked is, why FTP instead of a synchronized database? If
you are at this scale of operations, then it would only be fitting to have
the proper architecture for it.
