FAQ
Q: Can RC522 read 125kHz EM4100 cards? No - RC522 operates at 13.56MHz (ISO 14443A) only. For 125kHz EM4100/HID cards, use an RDM6300 or EM-18 125kHz reader module.
Q: How do I read the card UID with Arduino? Install MFRC522 library by miguelbalboa. Use the DumpInfo example to read UID and card memory. UID is typically 4 bytes (8 hex characters) for S50 cards.
