Pole display?

Barber? Flag? Magnetic? Pictures of residents of Poland?

I belive opticteam is referring to the pole display of a point-of-sales system.

What kind of interface does the display have?

I haven't touched a POS machine in several years, but on the last one I saw, the pole display received raw text on the parallel port.
