Could you tell us more about how the QR code is done? Is it engraved in or printed on the metal?
Is this what you're looking to change? Keep us updated, this is really cool!
The process, which works well on other metals, used lasers to fuse a metal emulsion. But the process just wasn't so great with these plated keychains.
We are trying actual engraving now, as well as offering other, similar crypto-products. Sorry it's taking awhile!
