I am currently working on my university project on a topic "RFID school attendance system".
I have borrowed raspberry pi 2 model B from my colleague and installed fresh NOOBS/Raspbian OS into the SD card.
I have followed each possible tutorial on the internet regarding the wiring/reading/writing the raspberry with RC522 but I am still unable to read/write tags.
I have followed these specific guides lately:
1. https://www.raspberrypi-spy.co.uk/2018/ ... pberry-pi/
Everything works like a charm up until it asks me to attach the tag to the reader. When I attach it - nothing happens.
I have soldered the pins to RC522 without issues. I have literally tried everything possible. Firstly, I thought that the tag cards I have does not work at all, but I have tried reading them using an android with NFC and it was read without issues.
Wiring is done exactly the same as on the 2nd link above. I have also tried different wiring based on other tutorials but the output is still the same - unable to read/write tags.
Could you please give me any tips on this? I'm desperate on finishing this project as soon as possible.
Thanks in advance,
