A code that can't be scanned isn't a code — it's a liability. As global traceability mandates tighten and 2D DataMatrix adoption accelerates across automotive, aerospace, medical device, and industrial manufacturing, more companies are asking the same question: laser marking or inkjet coding — which one actually protects your product's identity for life? The answer isn't about brand loyalty or habit. It's about matching the right direct part marking (DPM) technology to your part's material, environment, and traceability requirements — before a failed scan on the production line or in the field costs you time, compliance, or a recall. Here's what manufacturers need to know before choosing between these two dominant coding technologies.
