what interferes with rfid
To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). 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.

1. Metallic materials are interfering with the operation of the RFID reader or RFID/NFC chip. If the RFID reader is attached to a metal housing or if it lies on a metallic base, the reading distance between the reader and a tag . I have tried the cards that came with the device, cards that I got from a previous RC522 that arrived broken, and cards I got from hotels. I have both the small round keychain cards and the white credit card sized ones, and neither will read.
sending an identical gliched readout from any RFID card; stops reading or sending RFID data completely; After I close and open the COM port window, it works fine for a few minutes again. Some of the RC-522 RFID card reader modules that can be bought on ebay / aliexpress have a problem: they do not read all (types of) cards they should be able to read. In this blog post I want to explain how to recognize these faulty readers and how to fix them. 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.To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M).

rfid reader not reading card
Read the RFID card UID. Get the selection from user using pushbuttons. Restart the code for new cards. The problem is, It reads the card and gets the input from pushbuttons. But after the first loop, It doesn't detect other cards (or the same card again). I am working with RFID-RC522 and Arduino UNO. I have check pin configurations again and again tried different libraries. It is not reading card and red led on RC522 is consistently on. 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.
