RFID Wall Project -- What do I need?
I'm a software engineer and I don't know very much about RFID other than it's prox-based and returns a 10-digit UID. Basically I want to have an entire room with a bunch of sensors on the walls. As the tags come within range (0.5m would be the most that's needed; too far of range would actually be bad), I want to send my server a message with the scanner and tag IDs. It'd be nice if I could keep the price of every sensor to < $15.
I found a tutorial on how to get the reader info in python, and once I'm in software, I can obviously take it from there easily. Some of the things I'm not sure about:
Do I need a scanner for every sensor or would I just use separate antennae with a single scanner?
Will putting them behind objects interfere with or even block the reading? Ideally, I want to be able to put them behind plywood, concrete, and urethane, but I can put them on the outside if required.
Any advice on which specific one I should buy?
