Anyone know of a cheap/working rfid reader? I’m thinking of using it for access control, and user information polling. It will be used in arduino and raspberry pi projects.
Do you need just the bare chip, breakout borad or also a USB host?
First I’d like just something I can use with an arduino,so I’m guessing a
USB host as well.

I have a USB RFID reader like one of these on Ebay. They are usually under $10 shipped.
It actually works like a keyboard and sends keypresses to the computer. Mine works great with my Raspberry Pi, but I don’t think it would be worth the effort to get it working on an Arduino, since you probably need USB host capabilities.
Since it sends key presses, it was incredibly easy to work with. You can create a normal command line program that reads input off the console. The reader even sends an Enter keypress after the RFID number. I set up my Pi to auto login a restricted user to a local console and then to run my program on startup.
