There is no modification to AuthorizeNet.pm or the charge tag?  I
should be able to do something like this as long as
mv_credit_card_number is set to the last 4 digits?

[charge gateway="authorizenet" id="myid" secret="mysecret"
transaction="credit" orderid="myorderid" auth_code="myauthcode"]

What is an auth_code?

Thanks,
Grant
