A customer display is the small screen on the customer side of the counter. There are two families — command-driven VFD and pole LCD units, and HDMI screens that are simply a second monitor — and they are not interchangeable. The readable parameter is character height in millimetres, not inches.
A cash drawer has one cable and no power supply. It opens because a printer or a terminal sends a pulse to a solenoid, and it stays shut when the voltage does not match. The parts, the sizes and the counter math behind the last line on a POS quote.
The types of POS system are usually listed by software feature. The useful split is physical: does the customer come to the till, and does the till move? That decides the footprint, the service access and what breaks in year three.
A POS system is not a queue of steps. The terminal, the printer and the cloud run on three separate clocks, and only two of them are inside the customer’s wait. Following one sale through the hardware explains most of the behaviour that looks like a software bug.
EPOS stands for electronic point of sale — the British and Irish word for the machine North America calls a POS system. The acronym is the easy part. The hard part is that the same four-letter word covers hardware, software and a payment contract, and two quotes rarely mean the same thing by it.
An all-in-one POS system is a terminal with the printer, the customer display or both built into the same box. The saving is one power cable and one footprint; the cost is 40 watts, 2 kg, and a till that leaves the counter when the printer jams.
