Credit card transaction processing - step by step

[Myriad]

This article describes the complete process in detail .

I never realized quite how many steps were involved in processing a single transaction .

To my thinking , more steps means more potential vulnerability , and yet it all seems to work OK ,
.... in most cases

I thought it was a good read .
