Quality evaluation should focus on the material grade, typically 304 or 316L stainless steel, which offers superior corrosion resistance. Check the surface treatment process, such as PVD (Physical Vapor Deposition) coating, electroplating, or laser engraving, to ensure the finish does not peel or scratch easily. For dual-interface cards, the bonding strength between the metal face and the plastic inlay is critical; request delamination test reports to ensure the card won't split under daily bending stress. The weight should typically range between 15g to 28g to provide a premium tactile feel without exceeding ATM intake limits.
