I have a new soark and I have a QR code on batteries, RC, power cabe and other accessories.

Are the the serial number or just a reference for inventory?

thank you

Try to register and activate your spark and you'll see

For most of the QR codes on the accessories, they doesn't have a specific usage. When you scan the code of the battery, it shows a serial number, and sometimes we could check the activate time of it. For other accessories, they usually have obtain 3 months' warranty time. That't it. No big use for flying.
