I just finished re-writing the 6.0 module from NovaPoint for OpenERP v7 not too long ago. You're welcome to use it as a reference. We never process credit cards directly on sale orders due to our customer base, so there's a number of features that I didn't bother to flesh out. There are also several CIM methods I didn't bother with due to how infrequently we use them, but using the existing wizards you should be able to quickly add those remaining features in.

My apologies for the odd bazaar organization, I always use git and am not familiar with hosting bzr projects on launchpad. Couple notes, you'll need these three modules:

• account_payment_cc
• account_payment_cc_authorizenet
• rsa_encryption

I split the main CC processing code into two modules because we may be moving to Chase Paymentech in the future, and I wanted to leave the code relatively abstracted so I can easily add their API in. Also, I'm using urllib3, which wasn't included in Ubuntu until 13.04 I believe. Probably don't need to, but I copied it from my shipping API code, and I needed something thread safe to query multiple shipping companies for quotes at once. Anyway, you can get the source code for that here: https://pypi.python.org/pypi/urllib3

Card information is either stored in the Authorize.net CIM, or as a one-time use card saved directly to the account_voucher record (card info is purged once the payment is validated). CIM records are created/stored on the res_partner record of a contact. rsa_encryption is used to encrypt sensitive fields in the voucher record, so you'll need to generate a public/private key pair before storing any encrypted data - those functions are built into the module so that can be done from OpenERP directly. I recommend a key size of 1024 or 2048 bits, if you go higher the database fields probably need to be expanded.

Feel free to send me any questions you have setting that up.
