When the QR code function is enabled, return visitors simply use their Visitor Badge to sign in instead of going through all the steps every time.
However, for higher security, some organisations may wish to setup a QR Code Expiry Period which will prevent badges from being used after a certain time has elapsed. This helps prevent badge misuse.
By default, QR codes printed on the visitor badge will not expire.
To setup an expiry period, please go to:
home screen > SETTINGS > Badge Template
Scroll down to Badge Expiry
Choose an option from the drop down menu
Click Save Changes
