A senseless relic of the past and simply the unwillingness of the Ministry of Transport to modernize. Instead of putting vending machines in transport that issue tickets when paying with a card (and such machines stood 6 years ago on the same stone hill, but disappeared), they still put citizens on the minimum wage in these booths. You have a "Pay" (which, by the way, works extremely poorly with transport traveling beyond the MKAD), make online travel cards and vending machines accepting card payments inside transport, free citizens for more useful specialties and make life easier for citizens using the Ministry of Transport.
In the end, ask Muscovites, they will teach you, at least you can contact me, we will do everything 🫡
