title: Basic queue management system
body: <p>I wanna create queue management system (for bank, hostpital...) Something like that <img src="https://i.stack.imgur.com/PhuLG.jpg" alt="enter image description here"></p>
  
  <p>There will be</p>
  
  <p>1) Server side pc with touch screen monitor</p>
  
  <p>2) Standard or led display for displaying current number in queue</p>
  
  <p>3) Client side pc's for controlling queue</p>
  
  <p>The cheapest way is to use led displays. I can create c# app with tcp-ip protocols. But i dunno how to send value to led displays. I can use tablet pc-s with ethernet or wi-fi devices for that purpose (INSTEAD OF LED DISPLAYS). But it is very expensive method. Please help me to choose optimal variant for that purpose. </p>
