public enum MfrcCommand

Fields

CalculateCrc = 3

Calculate CRC: activates the CRC coprocessor or performs a self test

GenerateRandomId = 2

Generate Random Id: generates a 10-byte random ID number

Idle = 0

Idle : no action, cancels current command execution

Memory = 1

Memory: stores 25 bytes into the internal buffer

MifareAuthenticate = 14

Mifare Authenticate: performs the MIFARE standard authentication as a reader

NoCommandChange = 7

No Command Change: no command change, can be used to modify the CommandReg register bits without affecting the command, for example, the PowerDown bit

Receive = 8

Receive: activates the receiver circuits

ResetPhase = 15

Reset Phase: soft resets the MFRC522

Transceive = 12

Transceive: transmits data from FIFO buffer to antenna and automatically activates the receiver after transmission

Transmit = 4

Most of the time, the only one you need to use is the Transceive command. The SendAndReceiveData function is already using some of those commands to allow send and receive scenarios
