Hello
Please read my bid seriously. My name is Umer and i am a 15+ years experienced software engineer who worked in a Queue System company you might have heard about Qmatic, Wavetec, Stech, Intelvision etc. I have developed Queue System in windows, linux , android etc many flavours and know about the queueing domain from basic components like Queues/Categories/Counters/Operators to advance conepts like Blackhole, SLA, Woorkflows etc. When we talk i can explain you more about these.
Apparently you are looking to create mobile couunters and use android tablets/phones at the desk and Queue Server on PC which makes perfect sense. I am just waiting for you to get back to me.
Best Regards
Umer
