I got an RFID reader and hooked it up and got it mostly functioning with the system but I don't use it regularly for a few reasons:
- It runs on a seperate python script from the web interface for record selection and you have to SSH via terminal to start the script. Not elegant by any means.
- It's not 100% accurate or reliable. It may be hard to tell in the video but the 3rd record I scan (At the Drive In) doesn't produce any new blinking LED, but then when I scan a 4th record, the LED for the 3rd record's location shows up. Haven't really looked into why it's not funcitoning correctly.
- I only have 4 sample tags and I'd need to come up with a solution for getting ~1,000 uniquely addressed RFID tags and I haven't done the research into that.
- The whole RFID thing was put into question when a Hackaday user suggested using barcodes instead. That may be more reliable, even if it's less technical and wizard-like.
