摘要

The widespread proliferation of smart phones and wireless communication technologies continues to inspire innovation in the many ways these connected devices can be used, from monitoring home energy usage to remotely unlocking your automobile or residence. With the expansion of the Internet of Things (IoT) and the convergence of computer and telecommunications technologies, the wireless phone has evolved to become an individual's primary link to the world around them. Therefore, it's only natural that the same phone that people use to shop, pay bills, and stay connected could also be used to manage physical access.
