Do-it-yourself POS terminal or how to connect egais?

Question

Do it yourself

The question arose of connecting the store to the EGAIS system. The network is full of various offers to do everything quickly and on a turnkey basis, but somehow I don’t want to throw off 70 thousand checks for a tablet with a printer (wiki mini). There was an idea to assemble a POS terminal on my own, the benefit of the old, and not very full of iron, but from a specific one, the same 2D scanner on Ali Express is sold for a thousand and a receipt printer for two, in fact, I am interested in software for Linux and mentoring advice

Answer 1

Doesn't the equipment have to be certified to connect to the system?
You can collect anything, but I do not believe that you will accept it.

Read the official site. Nevertheless, it is clearly written - requirements for hardware and software, certification is not required.

Answer 3

Any computer, OS is supported from win 7, make no mistake with the choice of fisk. registrar, not everyone can print a QR code, some require paid revision. Scanner ... here you need to read the reviews. Someone worse reads the code, someone better. Download UTM from the site, get certificate files, 1 for each checkpoint, order a Jakarta key (3000 + 2000), and in principle, you can start tests (this is if without 1C).
