I laser engraved my name and a QR code inside my wallet for when (and if) I lose it
Once scanned it has all my social media and email contacts.
The first line it was my first time engraving with the 1600mW - I set it to 40% and it ended up burning too much and the small text became unreadable. For the QR code I set the laser power to 15% and it was much more accurate.
The QR code scans perfectly
