Conveyor Product Tracking

[lachuupriya]

I'm a newbie to tracking concept. I have assigned a project to handle product tracking. Product should be delivered to destination without any lost.
Few parameters need to be considered Conveyor Length, Encoder(Using U sensor), Photo Electric Sensor(Only @ Head of Conveyor).
My questions how to generate ID, how to track product and how to transfer id to upstream conveyor.
Your inputs will be highly appreciated.

I think there are past questions about this same issue. I would search first.
