No cost is not correct. ATMs, security and bank softwares, machines to do
transmission of data, lease lines, networks.....

All that's built into the cost of credit card processing which is charged to the
retailer and is incurred even when there is no currency conversion. How do you
think these costs are met when people buy stuff in their own currency? The
retailer typically pays around 2% of credit card receipts. The DCC markup is *on
top* of all that.
