It's also possible to start a scan with an "unlock mode" (see XAML example below). In this mode, the app doesn't rely on the [[#Searching_for_objects|search mechanism]] to find the objects and, therefore, doesn't present anything in the UI. Instead, any objects having their [[SYSCLS_UNLOCK_GROUP_BY_SCAN|unlock code]] matching the scanned unlock code one are unlocked in the background.* It's possible (but optional) to specify an expected unlock code as well. In this case, nothing gets unlocked if the scanned code doesn't match the specified one;* It doesn't matter whether objects having the unlock code are present at the time when that code is scanned or not. The scanned unlock code will be remembered for 15 minutes. If objects carrying that same unlock code show up on the client (locally created or downloaded from the server) within that time, they will have an unlocked status automatically;* It's possible (but optional) to specify an expected unlock code as well. In this case, nothing gets unlocked if the scanned code doesn't match the specified one.
