I am sorry if I sound a bit nooby with this basic question, but I have explored the beauty of the collectibles in this forum just recently. So, what I do not understand is how do I conceale the QR code exactly? I get that I put the QR code into the collectible then what do I do to conceale it?
Each wallet ships with 3 self-stick holograms. Once the code is put into the spot on the coin, you take a hologram and slap it over the code. The hologram is only sticky around the edges, so it won't stick to the code and have any chance of destroying it.
The holograms are tamper-proof, meaning that if they are peeled, there's a residual part of the sticker left there so it can't be stuck back on over itself and look like it was never touched. The residue can be cleaned off and a brand new holo applied for re-use, which makes these rounds useful longer.
