USI

Overview

Universal Stylus Initiative: https://universalstylus.org/

The Universal Stylus Initiative is (was?) an organization to create apparently some kind of stylus specification. Ultimately, few styluses are USI and those that are are poor quality compared to a traditional EMR pen. I highly recommend avoiding devices that use a USI stylus.
