Repeating visitors can present their visitor badge to scan sign in.
For higher security, some organisations may wish to setup a QR Codes Expiry Period. After certain time range, QR codes will expire, and repeating visitors have to manual sign in again.
By default, QR codes printed on the visitor badge will not expire.
To setup expiry period, please go to Settings>Printing> Visitor Badge
Scroll down the page, and choose the time range. Save and then this setting will be applied to all the terminals.
