Do you mean that humans will have to decode Base45?

If not, there is a software layer anyway. Adding another skin to the onion is not the best way to compress data.

The issue is that there are two layers of software: the SDK, and the software which you write which uses the SDK.

If the crash is happening in the SDK (on binary QR codes), then your only option is to ditch binary QR and implement a workaround.
