Why do they need that? Amazon awarded a patent for ultrasonic wristband that can track...

•, by: Frances Bloomfiel

 Internet retail behemoth Amazon has been granted two patents for employee-tracking wristband system. Originally filed back in 2016, the United States Patent and Trademark Office (USPTO) published the patents on January 30 of this year.

The proposed system would be composed of three elements: a management module to oversee warehouse operations, ultrasonic devices planted around the vicinity, and the wristbands, which have been outfitted with ultrasonic units.

According to, these ultrasonic units would be used to monitor the hand movements of warehouse workers handling inventory bins, with data on their hand positions being transmitted to Amazon in real time. Vibrations coming from the wristbands will guide workers' hands to the right direction. If they move to the wrong item, then the wristbands will buzz.

If proven to work as intended, Amazon may implement this system into other aspects of their enterprise, such as in shipping.
