Why Kopirkin is better than ...

... similar devices

Even though coin or card operated copiers are present on the market for a long time, most of them are not suitable for business applications. Mostly they are stand-alone modules, which are attached to copy machine and control it.

Such approach has a major disadvantage: copier, especially high-performance models, is very fragile and vulnerable equipment. You cannot leave it without constant supervision by staff - and even then it can be damaged by inexperienced user.

There is another disadvantage - copier has relatively complex user interface, usually with several buttons (even though most of them are not needed for simple copying).

Kopirkin, on the contrary, is very robust and easy to use.

... copy machine with human operator

This combination has some advantages, for example broader possibilities of copying (scaling etc.). However, it also has a numbet of drawbacks which make it poorly usable for "added-value service" or "network business" applications.

Human operator has to be paid a salary, and it boosts cost price of a copy. Copy machine with operator requires considerable space, compared to 1 square meter needed for Kopirkin. You will have to solve the problem of protecting the copy machine while operator is not around (outside of working hours, on lunch hour etc.).

Kopirkin requires only 1 servicing person per 20-30 devices, considerably lowering spendings on human resources management. It won't take a leave, and will work 24/7, maximizing revenues.

... any other vending machine (as a business) 

Unlike traditional vending machines, market for automated photocopy services is far from saturation. Snacks and coffee machines are installed everywhere - but did you see a photocopy point even where it would be obviously useful?

Besides, most vending machines have complex logistics - for example, you have to monitor and refill supply of whole range of snacks in snacks machine, or deliver heavy water bottles to coffee machine.

Kopirkin costs 2-3 times less than traditional  vending machines, its market has much more unused potential, and its logistics is much simpler.
