I need to implement a system which tracks individuals passing through a door. The individual will need to carry a tag of some sort for identification, which can be in their backpack, pocket, purse, etc. We do not want people to have to swipe a card, so close proximity RFID is not a good solution. The budget is around $500-700 for the entire solution (excluding the cost of any computers). The range that the scanner will need to be able to detect a tag inside of a backpack, etc., is roughly 8ft.
What sort of technology may be a good solution to look into? It turns out, through researching RFID, that the obvious choice of RFID gets expensive for reading at that range.
