Laser engraving is the cleanest permanent mark route for metal RFID cards: a fiber laser alters the metal surface itself, so the mark cannot peel, fade, or wear off. It is the choice for restrained logos, fine linework, serials, and NFC icons — with tone, line width, and contrast approved on the final finish rather than on screen.
Four laser references across stainless, black, and brass: mark tone, tone-on-tone contrast, warm-metal engraving, and production alignment.
Laser behaves differently on every face in the range. On brushed stainless the mark reads tone-on-tone and stays subtle; on matte black PVD the beam removes the dark coating and exposes bright steel — the strongest contrast available; on brass and copper it burns a darker, warmer mark. The finish is chosen with the mark, not before it.
Approve laser tone, line width, contrast, and the finished reader-tested card sample.
The practical route is selected from the system, audience, and handling context before the final metal finish and mark treatment are approved.
Metal card production should confirm body construction, finish, chip route, data handling, marking layers, and approval samples in one brief.
Yes. The mark is made in the metal surface itself rather than printed onto it, so it cannot peel or fade. On coated faces the laser exposes the base steel, which is also what creates the contrast.
Logos, fine linework, serials, member numbers, contactless icons, and data-matrix marks. Minimum line width and the smallest readable detail are approved on the actual finish, because tone and contrast shift per face.
Surface laser marks do not reach the antenna, but their position is still checked against the RF stack — and a request for deep, tactile marks moves the conversation to depth planning before a sample is cut.
