First, a short preface:Payment terminals of the company OSMP (United System of Instant Payments) - (IMHO) occupies the leading place among similar services at least in Nizhny Novgorod. Such terminals are everywhere, in many stores (and other places of large crowds of people :-) and allow you to instantly pay for mobile communication, transfer money to WebMoney and many other "wallets" and bills.
A bit of historySince January 1, 2008, new features have been added to OSMP machines (

Easter eggsFor those who are not familiar with the subject, the
article in the wikiAnd to begin with, even not quite an Easter egg, but simply a fact that few people have noticed. The interface of the machine depends on the current time - from 8 pm to 8 am the machine looks like this:

And here is the first Easter egg left by the developers. Click on the tree on the main screen, and there will be such a bear:

The remaining three Easter eggs appear at random times.
First, another bear:

Secondly, a bear, but a classic one, with arms raised:

And the most patient can get such a cool cartoon about rats chasing a mumps :-)



In conclusion, I want to say that OSMP programmers once again pleased users with the so-called “hidden functions”, which do not carry a semantic load, but, firstly, they are just pleasant and create a positive atmosphere, and secondly, they can be attractive users. to use these payment terminals.
Thank you for your attention, I will try to continue to notify the habrasoobschestvo about such things here :)
Sincerely, Rozboris
