Here's a QR code leading to
bluefirereader://nav/transfer for those who use that method of transferring books. It's probably easier to save a bookmark than to scan a QR code, but at least it looks cool.
To the interested, this code was generated with
QR-JAM (Japanese). The books aren't being corrected for by the QR code's built in error correction, but are actually a part of the code.
