Communication overview for ISO/IEC 14443 A/MIFARE reader/writer
8.1 ISO/IEC 14443 A/MIFARE functionality
The MFRC523 transmission module supports the Read/Write mode for
ISO/IEC 14443 A/MIFARE and ISO/IEC 14443 B using various transfer speeds and
modulation protocols.
The physical level communication is shown in
The physical parameters are described in
The MFRC523’s contactless UART and dedicated external host must manage the
complete ISO/IEC 14443 A/MIFARE protocol.
