# Metal Card Customisation ## What is Metal Card Customisation? **Metal card customisation** refers to the process of designing, personalising, and manufacturing premium payment, membership, or identification cards using metal alloys instead of traditional plastic. This service caters to individuals and businesses seeking a tangible symbol of status, exclusivity, and durability. From my personal experience working with luxury brands, the moment a client holds a custom metal card, their perception of the brand's value instantly elevates. The weight, the cool touch, and the distinctive *clink* sound create a powerful, memorable unboxing experience that plastic simply cannot match. ### The Technology Behind Custom Metal Cards The ability to create these sleek, functional pieces of art relies on a blend of advanced manufacturing and embedding technology. A key personal skill I've developed is understanding the precise tolerances required for these cards to remain functional in global payment systems while achieving stunning aesthetic results. #### Technical Specifications and Parameters For those interested in the engineering details, here are the typical technical specifications for a standard custom metal card. *Please note: These technical parameters are for reference data only. For exact specifications, you need to contact backend management.* * **Standard Dimensions:** 85.60 mm × 53.98 mm × 0.76 mm (ISO/IEC 7810 ID-1 format). * **Core Material:** Often 304 or 316 stainless steel, but can include brass, copper, or titanium composites. * **Weight:** Approximately 18-28 grams, compared to ~5 grams for a plastic card. * **Contact Chip (EMV):** Typically uses a secure microcontroller like the NXP SmartMX2 P60 series (e.g., P60D144, P60D48) or equivalent from Infineon (SLE 78 series). The chip is milled into the metal substrate. * **Contactless Interface (NFC):** Operates at 13.56 MHz (ISO/IEC 14443 A standard). The antenna is often laser-etched or embedded in a composite layer. * **Magnetic Stripe:** Hi-Co stripe (typically 2100 Oersted) is laminated in a recessed track for reliable swiping. * **Personalisation:** Laser engraving, colour fill (enamel or CVD coating), and selective polishing for finishes (brushed, mirror, ma
