offline credit card built in

I know i've seen offline credit purchases module for sale on another site but this should be easy to integrate into the core. I'm looking for the ability for encrypting card numbers to a database and organizing customer order then processing the card at the brick and mortor store. Is anyone working on such an option? I'm not sure if there are any free modules i can try but i'm not convienced on buying one i might not use and am not sure is safe.

I should say that this function is requested by a client of mine so i can't use another merchant option, ie paypal, due to the cost he paid for businesses card processing set up. Also i need to ensure him that the transactions will be secure. This option could send me looking at other carts if i can't find a suitable solution.

The latest version of my offline cc module does have encryption. It is available now from my store:

Qphoria, I purchased this module from you. One thing I would like changed is the cvv number. I don't want to collect or store this information, because PCI Compliance forbids storing it. Is there a quick way for me to remove it from the module?

thanks!

Find and delete: But then you can't use it for processing cards?!

sure you can, payment gateways will accept payments without that code. the code is there for added protection against fraudulent purchases. Storing though is explicitly prohibited by PCI compliance.

to show you in the actual document, I'd have to download the PDF from https://www.pcisecuritystandards.org/ but this website also talks about it and what you can/cannot store. http://tinyurl.com/6fgtac

I've found it depends. I have an authorize.net account and I can require or make optional certain fields to use as part of the verification step. So if i was required then I would need it. All the same... do what you want with it.
