rfid chip sleep on command I managed to find the closest answer which is use the following command: mfrc522.PCD_WriteRegister(CommandReg, 1, 0x10); // Set the power down bit to reduce power consumption. The problem is that CommandReg is not declared. How RFID/NFC Door Lock Works. The UIDs of authorized tags (key) are .

The command and response messages both include a TFI (Frame Identifier) and a command version. The command uses a TFI of 0xD4 and the response uses 0xD5. The command versions vary but the response will always increment the command version and return it in the byte following the TFI. I'm trying to get the power consumption of a MFRC522 RFID module down, currently while running it consumes about 4mA. There should be a way to put it into sleep mode, I just can't find any documentation on it.
