Abstract
A method of power optimisation in an RFID device includes harvesting power from a radio-frequency excitation field using an antenna, powering a biometric authentication unit and an RFID communication module using the harvested power from the antenna; monitoring the voltage of the power supplied to the biometric authentication unit, and controlling a clock speed of a processing unit of the biometric authentication unit based on the monitored voltage by operating the processing unit at a higher clock speed when a high voltage level is detected and at a lower clock speed when a low voltage level is detected.
