Answer 1

Of course, you can completely fill that part of the terminal with alcohol (can be isopropyl) and lower the bath (ultrasonic cleaner) into the ultrasound, but if something is rotten there, it will not help.

Answer 2

Temporary replacement of non-cash payment?
In one of the nearby shops I saw the use of Internet acquiring. That is, they asked live offline buyers to pay with cards right on the trading floor, as if they were buying over the Internet. (Apparently, their acquiring was hooked up to some physically absent cash register - if not to a service like Robochekov.)
Have you bought a cash register or are you renting it? There are no programs for such cases? Like providing a temporary replacement for the period of repair or maintenance? ..
Otherwise, it remains only to kick the repairmen to repair urgently.
