Offline data sync from an old device to a new one. Many phone carriers provide for something similar in a QR code. My team has an app we developed that has a similar function because the private keys and all of the wallet items are exclusively offline. We show an qr code today. The issue we have hit lately is that the amount of data we have is more than a single code. Depending on the number of wallet items the users have. The animated QR is a good solution for this.
If someone is interested in how we got an amazingly small QR using base-91 and some other cool methods here is a good read with demo code
