In our experience, these are some of the factors for RFID reading failures: Reader Quality. Speed and Movement of Tags. Tag Density. Antenna Design. Cable Type and Length. Mounting Location. Transponder Sensitivity. Absorption and Reflection. Electrical Noise. Environment. Reader Sensitivity. Material Density. Operating Frequency/Coupling Factor.When * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output * will show the ID/UID, type and any data blocks it can read. Note: you may see "Timeout in communication" messages * when removing the PICC from reading distance too early.

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 .
