Perhaps every visit to any government organization begins with a queue. People wait for hours, crowding and jostling in narrow corridors, and sometimes they find out by force who was behind whom ...
Sometimes it comes to madness:
It's unbelievable, why, so far, we still haven't decided on a problem that many other countries use? Why we do not have an electronic queue? ')
What can be easier than getting a number, and be free until the number appears on the board! - that's your turn.
The number printing machine is very simple, no more complicated than an ancient dot-matrix printer. The scoreboard is also nothing complicated. How much can a similar system cost?
I think most of the people standing in the 2-3 hour queue would gladly donate $ 2 - $ 5 to leave this queue and return when necessary. In addition to the scoreboard, you can make a simple web site that can be viewed from a mobile, or by SMS notification. And cheaters can be screened out by printing a bar code along with the number. I think you can even monetize this system by getting a small amount for SMS notification.
So what's the problem? Why don't we value our time and spend so much in queues as on video?
