I'm using the reader below to read mifare cards (13.56mhz), I have an electron/node.js application for this. For some reason after an uncertain amount of time(shortest time I noticed was about 30 minutes) the reader just stops reading, but the power is still on indicated by a red LED on the reader.
I'm using this to do the card reading and also followed the gpio wiring shown. I'm having a hard time figuring out what's wrong since I only experience this on my Pi 3 Model B+(2017), I also have Pi 4's which I don't experience this in. Sometimes restarting the application works and it can read again, sometimes I have to reboot the pi itself. Both are running buster, updated. Same application.
