• Fasten a neck strap to your old USB flash drive.
• Fasten the other end of the strap to a table.
• Plug in the USB flash drive into a USB port of a laptop.
• Lock the laptop by pressing the Windows logo key and L key together.
• Define zones like Home or Friends where you know laptop would be safe.
• Send alert to Mobile Device.
• Destroys all your personal data if configured. This tip is also useful if you worry about identity theft.

When a thief removes the laptop from the table, the USB flash drive will be disconnected from the laptop and then a loud siren sound will be emitted.
