"running XP is not really that bad especially if the machines are not connected to the Internet"
For point of sale equipment, it is almost certainly connected, if not to the internet at large, at least a corporate network. You could create a communication system that lets information about payments be sent out without networking, but that is difficult and probably wouldn't be attempted. These vulnerable devices have been used before to gain access to payment information, usually after a breach somewhere else in the network.
