Amazon patents wristband that tracks workers

Amazon, which is already known for closely monitoring its warehouse workers has been granted two US patents on a wristband that could use ultrasonic sound pujlses and radio transmissions track a worker's every move, pause, or fidget, and vibrate to provide haptic feedback to nudge them when they make an error. It is unknown whether the company intends to manufacture the wristbands or issue them to workers. In the patents, Amazon says the goal is to streamline time-consuming tasks.
