Precision CNC-Milled Slot: Our metal credit card blanks utilize specialized milling technology. This ensures your contact chip sits perfectly flat with a zero-gap fit, providing a highly reliable insertion experience in all standard chip readers.
PVD Matte Black Finish: We employ vacuum PVD plating to achieve the deep, anti-reflective finish on these black metal cards. This results in a highly scratch-resistant surface that is anti-fingerprint and won't flake or peel during DIY fiber laser engraving, ensuring your design remains sharp and professional.
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: Our metal credit card blanks feature a factory-applied magnetic track. Using a high-temperature bonding process, we ensure the stripe is molecularly fused to the steel, providing maximum adhesion strength for long-term usage.
Durable Stainless Steel Material
These metal credit card blanks are made from stainless steel, providing high strength and resistance to bending or wear during long-term use.
Standard CR80 Size
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.
Chip Slot for Smart Card Applications
The blank metal credit card with chip slot supports 4428 or 4442 chips, which are commonly used in identification, membership, and access systems.
Magnetic Stripe and Signature Panel
The back of the card includes a magnetic stripe and signature strip, allowing manual identification or magnetic data storage if required.
Matte Black Surface
The matte black finish provides a clean appearance and works well with laser engraving or other personalized branding methods.
