hi have no experience in data structure "list" i did the first steps as from the pictures you sent installing the pip3 for mfrc522 and the python3 however a message displays up
ImportError: No module named mfrc522
>>> RFIDModule = SimpleMFRC522()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'SimpleMFRC522' is not defined

pi@raspberrypi:~ $ sudo pip3 install mfrc522

@627117717.pr Ah, let me see. So your reader can write 'parcel 1' and read back. That means read and write are OK. Next step is to use python 3 to execute read.py and write.py. BTW did you use a multi-meter to solve your last problem?
@627117717.pr And please tell me more about your programming background. Eg did you have any experience to us Rpi python to blink a LED and read a button? Or have you played with Arduino before? Do you have a multi-meter and know how to measure the resistance?. And have you heard of "Ohm's Law". "Pull up" etc?
