Precision CNC-Milled Slot: Our metal credit card blanks utilize specialized milling technology. The milled slot is designed to seat the selected contact chip module. The final fit should be checked against the chip model, module dimensions and intended reader system before bulk production.
PVD Matte Black Finish: We employ vacuum PVD plating to achieve the deep, anti-reflective finish on these black metal cards. The matte black PVD finish provides a dark, low-reflection surface for the selected branding process. Confirm the engraving depth, artwork and finish compatibility before production.
Deburred Safety Edges: Every artifact undergoes a mechanical deburring process followed by manual polishing. We ensure the edges are rounded and smooth to the touch, eliminating the sharp edge issue common in lower-grade credit card blanks with slot products and ensuring safe daily handling.
Integrated Hi-Co Magnetic Stripe: A magnetic stripe may be available depending on the selected card configuration. Confirm whether Hi-Co or Lo-Co is required before quotation. Using a high-temperature bonding process, we ensure the stripe is molecularly fused to the steel, providing maximum adhesion strength for long-term usage.
These metal credit card blanks are made from stainless steel, providing high strength and resistance to bending or wear during long-term use.
The card follows the CR80 standard format, the same size used for most credit cards and ID cards, making it compatible with many card holders and systems.
The blank metal credit card with chip slot supports 4428 or 4442 chips, which are commonly used in identification, membership, and access systems.
The back of the card includes a magnetic stripe and signature strip, allowing manual identification or magnetic data storage if required.
The matte black finish provides a clean appearance and works well with laser engraving or other personalized branding methods.
