The final "0" can be a candidate of the Rh designation if it is included in the tag. There are 10 possible values for this purpose (Ascii 30 to 39)I decoded it!
Following is the raw bytes of the QR code.
The first twelve bytes presumably are "李孟阳" in a unknown encoding.
Then we have "LI MENG YANG".
His blood type, "O".
His resident Identity number, "431121199604076911".
And finally a "0". The purpose of which remains unclear.
Again, the dog tag lacks the provision for Rh blood group designation even in this machine readable form.
But I doubt it.
