Method Details

getUserPresence

public byte getUserPresence()

Bit 0 is set to 1, which means that user presence was verified. (This version of the protocol doesn't specify a way to request authentication responses without requiring user presence.) A different value of bit 0, as well as bits 1 through 7, are reserved for future use. The values of bit 1 through 7 SHOULD be 0

getCounter
