Passing credit card info to email

I am putting Amember for my client website and he wants to use manual credit card payment. I told him that this is not safe at all, but he stil want to do it. basicly, everytime there is a sign up, member will filling credit card info then click on subscribe, it sends this member credit card info such as number, name, expiration date, member name ... to his email so he can process it with his credit card machine offline.

I look into file templates/admin/pending_mail.txt and I see this:

Code:

Subject: ** Pending Payment

{$name_f} {$name_l} trying to subscribe to your service.
His payment status is PENDING. 
   User ID: {$login}  
   

Now how do I add more variables into this email such as credit card number, expiration date, name, ..

I tried to put this in: Credit Card Number: {$members.data.cc_number} but it sending blank field.

Please help
Thanks

Yeap, I enabled manual_cc and that is why I want to pass credit card info to email as well.

So absolutely no way to do this?
