aw I'm sorry, I didn't define the GPIO pin to be the RFID reading data I/O pin. After I looked at AuspeXeu's program on the topic 'Connect two reader to one controller' I needed to define pins as in line.

this component does not work on my nodemcu when connected to the RX TX pin, but it works fine when the pin defined is different.
