The RFID Reader
The RFID reader has several wires but only 4 of them are used by our system. The unused wires
should be insulated from one another. The 4 wires that are used are coloured red, black, white,
and green.
RFID Readers with Screw Terminals
Some readers have screw terminals instead of wires. Use the following key to interpret the
diagrams. All other terminals are not used.
