So, this is a sample QR Code for the journal I just put in (https://inkbunny.net/j/433289). It's meant to be a basic 'sample' for referring to what a slave's tattooed identifier would look like as the QR tattoo based on the items in that journal entry.
This is the item list that should be retrieved from the code when decoded. GFR01-248702BDX-000275971,Generra,5,45750,Y,25,15,1,2,3,4,5,8,10,14,16,17,20,21 -- Remember this is meant to be a dataset list for apps that would identify what slave you're considering renting, its price, and the things it's usable to satisfy.
