Hopefully this isn't too broad of a question, I will narrow it down the best I can.
We need to add RFID tags to feeders on our pick and place machine, to determine that they are loaded into the correct position on the machine itself. Other than having a reader for every single slot, that only reads a single feeders RFID tag, what are my options?
I could have a single reader with longer range, but since the tags we will use will be passive, location tracking will not be overly accurate. I looked into phased array antennas, but they seem still experimental..
If we used a single RFID reader for each feeder slot, that would require over 100 readers..
I'm open to other technologies other than RFID, but I presume that it is the obvious choice.
