Is commercial equipment complicated? How does it work? And how to study it?

Question

System administration

And then in the vacancy it is indicated that it will be necessary to work with commercial equipment.
I do not know what it is, how it works and what operations should be performed with it.

Answer 1

I had a chance to work as an administrator in a hypermarket. Trading equipment is essentially the cash register itself, which is a regular computer with a castrated Windows, to which a small monitor, a cash drawer and a pin pad are connected. Pin pads are served by a representative of the bank. On the computer itself there is a special program in which the cashier actually works. Many networks have their own.
Further, price checkers go aloof, there you just go to the web face by ip. Well, a separate world is scales. Several companies produce them, they are blunt where you need to know key combinations for configuration. smoke manuals, but there are smart ones, for example, touch ones on which something like Linux is installed. With scales most of all hemorrhoids. But if there is a breakdown, again, call a specialist.
And the moral is this, you will only recognize trading equipment if you work in such an institution, you don’t need to study it specially.

Answer 2

Scales, fiscal registrars, barcode scanners.
They connect like any other devices - either via TCP / IP or via USB / COM
They come with utilities for configuration and management, but as a rule these utilities are not needed if everything is configured - it works for years.
Some types of barcode scanners are included in the keyboard gap, emulate the keyboard - and there are no drivers for them at all.

Answer 3

Usually this is a bunch of peripherals, most often, as already mentioned, a cash register (where money is removed), a barcode scanner, a receipt printer. All this is connected to a computer with special software such as r-keeper. In general, everything has instructions in Russian or paid courses. It is necessary to take a little time to study and use them as a reference. After all, the equipment is designed for salespeople to work with it, not for programmers.
