Design your Anodised black sticker, Pro chip
This is drawn at the size the object really is, from the same file the laser cuts — what you see here is what you get handed back. It reads 6–11 mm; change the material and that number changes with it, in front of you.
The dashed white line is the cutting tolerance; the copper band is the antenna, where a solid mark stops the card reading.
Anodised aluminium, lasered back to bare metal. A flat, single-colour version cuts best — under 200 KB, and a PNG is scaled down for you.
For the phone in front of you that will not do NFC. Every card gets its own code — the pattern is filled in when the tag is encoded, so the preview shows the reserved area at true size.
One pass. You feel the mark more than you see it, and nothing is removed.
readyEverything clears the trim edge and the antenna.
