PCI DSS: System components and serial connected terminal
Oct 2nd, 2007 by Jesper Kråkhede
I have been in deep discussions regarding several scoping issues in how to define system components and how we should look at different setups. One setup is where we have a till with a serial connected terminal where all logic is inside the terminal, a.k.a. smart terminals. Even with this setup the serial cable is regarded as a network and therefor makes the till in scope due to the definition of system components. IP-terminals is most probably the way to go if you have an old POS that you wont or can´t change.
