8.0 QR Code Pass Transfer Protection
When a visitor receives an email and click on the link at 11:41, the QR pass is valid from 11:41 to 12:11.
Later than 12:11, the visitor must click the link again to generate a new time range, until before the end time
21:00. This is to prevent someone taking a snapshot of a QR pass from yesterday.
After 21:00, the system will generate an invalid QR pass for preventing an access.
9.0 Door Station Offline Mode
IPC0522 door station is able to operate at offline mode where IPC0522 may not be able to connect to LILIN
Cloud for validating a visit. IPC0522 decodes the QR pass for opening a door. In contrast, if IPC0522 is
connected to LILIN Cloud, IPC0522 is able to check if a QR pass is removed from an access.
10.0 Device Cloud History Record
For valid QR pass, when the end time of a stay is overdue, the expired QR pass is recorded in the history
records and is retained for 30 days. After 30 days, the system deletes the QR pass automatically.
An administrator can use CSV exporting function to export QR passes for backup or promotion purpose.
