The POS can specify the time window during which the terminal management system update check should take place. The default time window is 4:30 AM - 7:30 AM local time.

:::::notice{note}

The update check will not disrupt an in-progress transaction or other card reader operation. If an update is needed, Commerce SDK will wait until the current operation finishes to perform the update.
