A user simply needs to install the SimpleAccess app and activate it with an email from the access control system admin. With the app open and bluetooth turned ON in the mobile device, a user simply needs to approach the SR3 mobile access reader. The reader will sense both the motion and reads the ‘mobile key’ connecting to the device via low energy bluetooth. The mobile device may be left in a pocket, purse, or bag. (No tapping, waving, or touching the reader.) This hands-free operation is both convenient and highly secure.
