In an industry with razor-thin margins, it is too costly to equip all guards with batons, two-way radio devices, phones, etc. This is particularly true when contracting guards on a regular basis for brief periods of time.
QR-PTT is an industry-specific app which only requires an Android or iOS smartphone. The user experience is simple and intuitive so new guards can get up to speed in only a few minutes.
Solo workers are no longer alone with QR-PTT.
