Sample of Authorization letter

This is sample of an authorization letter for payment with credit cards. However we are no longer using this method because it puts customers at a disadvantage. If you pay for our service with credit cards, we will provide you with a secure link for online payment, please see more details at our accepted payment methods

Some years ago, to make payment to Vietnam with credit cards, you have to show your personal and sensitive information like the authorization letter above. No more now with our online payment!
