Optional 2nd display as a customer display

what machine is this? It looks identical to the Olivetti 100's we use sometimes

It's a Flytech POS365 - Aures, J2, Olivetti, XN all bought machine in from them and rebadged them. Some like J2 and Aures had compltely new cabinets built but underneath it was essentially the same hardware

That a nice graphic rear display, I like it!
