T2 - FAQ - What does the QR code inside the case do?

The QR code printed inside the lid of the T2 charging case can be scanned to reveal the unit's serial number. 

By scanning the code with your smartphone camera or with third-party QR code scanners, the 12-digit serial number appears on the screen.

The serial number is required when you register your product to Sudio Sphere, and may also be required in a warranty claim process.

If you are unable to scan the serial number, you can also find it underneath a QR code on the product packaging.
