Read damaged DPM codes

Direct part marking that a scanner rejects? Upload a photo of a laser-etched, dot-peen or low-contrast Data Matrix on metal — Semacode reconstructs the image and reads it right in your browser. Free, no signup. Built for industrial 2D codes that regular readers give up on.

Three steps to your content

Photograph the mark

Snap the laser or dot-peen mark on the part, or drop in an existing photo. No app, no account.

Reconstruct & grade

The engine lifts contrast off the metal, evens out glare and curvature, rebuilds missing modules – and grades the mark honestly.

Stage 1: read the content on the spot, free. Stage 2: leave your email and we work on it and notify you.

What we can recover on a part

Stage 1 · Free

Low contrast & glare

Shiny metal, shallow dot-peen, faint laser marks, reflections and curvature – lifted and read right in your browser, free.

Stage 2 · Send it in

Scratched & worn

Scratched, corroded or partly worn marks where the structure still survives. Register, submit – we notify you the moment we recover it.

Stage 3 · Honestly gone

Physically destroyed

The finder border or clock track is machined or ground away – that information is no longer on the part. We tell you straight.

Frequently asked questions

What is a DPM code and can Semacode read it?
DPM stands for direct part marking: a Data Matrix code laser-etched, dot-peened or chemically etched directly onto a metal or plastic part instead of printed on a label. Semacode reads DPM codes from a photo, including low-contrast marks on shiny or curved metal, right in your browser. Nothing is uploaded.
Which DPM damage can be recovered?
Low contrast, glare and reflections on metal, shallow dot-peen, partial laser fade, surface curvature and light scratches are usually recoverable, because Data Matrix carries built-in error correction and our engine reconstructs the image. What cannot be recovered is physical destruction of the solid L-shaped finder border or the dotted clock track — those are not error-corrected, so if they are gone no tool can read the code. We tell you honestly.
Do you handle automotive, aerospace and medical UDI marking?
Yes. It reads standard, GS1 and UDI Data Matrix used for traceability on parts and devices. We have recovered a scratched Data Matrix from a damaged automotive part that normal scanners rejected. For badly damaged industrial codes you can send them in and we follow up by email — or ask about our recovery API for business.
