Read and Write RFid Data Using RC522 on Raspberry Pi

Introduction

I have publish a tutorial regarding this topic before, around 2018. But now the library seems not compatible. So I decided to create a new tutorial and add a write function. So in this video it will cover on how to read and write RFid data using Mifare RC522 on Raspberry Pi. I'm using the same hardware connection like the previous tutorial. You better check on the link below.
