What is the "Invisible ID Card" of Electronic Products?

Imagine each electronic device possessing a unique, indelible identifier – a digital fingerprint etched directly onto its surface. This is essentially the role of laser marking in the realm of consumer electronics. Unlike traditional labeling methods that can be easily removed, tampered with, or degraded over time, laser marking utilizes a focused beam of light to permanently alter the surface of a material. This process creates high-resolution marks, such as serial numbers, barcodes, QR codes, and even intricate logos, without physically contacting the product. This "invisible ID card" becomes an integral part of the device itself, providing a foundation for comprehensive traceability and enhanced product safety.
