Hi everyone I would like to talk about credit card security on the net, and see if in the US is the same.

I live in Australia, and everytime I want to buy advertising or anything on the net I have to call my bank and tell them who is the company that I am buying from and how much, after that the bank allows the transaction to go through, and after it is done the bank stops all other transactions from the net.

It is a very good system, BUT: Alot of my sales as an affiliate are reverse, or don't go through with most of the merchants I am with, and I was wondering if in the US or other countries the banks are using the same system.
