## HC Key Description
HC Key opens all the doors to your favourite places! Hartmann’s HC Key application eliminates the need to carry physical credentials and allows you to unlock doors swiftly and with ease, using your smartphone.

KEY FEATURES

- Replace traditional credentials by using your smartphone. 
- Grant temporary access to visitors for a predetermined time frame and amount of uses.

VISITOR ACCESS
