Countertop payment terminals are connected to the power supply and the internet via cable. Thanks to Ethernet, they function extremely reliably and stably. Stationary" means that they are installed at a fixed location - usually the point-of-sale (cash desk) in the shop. There are also models that are operated with WLAN, so there is no need for a cable.
These card terminals are particularly suitable for industries that cash up directly at the counter, such as hairdressing salons, doctors' surgeries or the retail trade.
