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.

Common Applications

These blank metal credit cards are often used for:

Premium membership cards

VIP club cards

FAQs

1

What material are the metal credit card blanks made from?

They are manufactured from stainless steel, which provides durability and a premium appearance.

2

What is the size of the metal card?

The card uses the CR80 standard size of 85.5 × 54 mm, the same size as most credit cards.

3

Which chips are compatible with the chip slot?

The chip slot supports 4428 or 4442 contact chips, depending on the requirements of the card system.

4

Does the card include a magnetic stripe?

Yes, the back of the card can include a magnetic stripe and signature panel.

5

Can the metal card be customized?

Yes. The card surface supports laser engraving, UV printing, and other custom branding processes.

6

Will the matte finish on these blank black metal cards peel off during laser engraving?

No. Unlike painted cards, we utilize PVD vacuum plating to bond the color to the stainless steel at a molecular level. Whether you are using DIY fiber laser engraving or UV printing, the coating remains stable with minimized coating deviation, allowing for high-detail custom designs without flaking or edge-wear.

7

How do I ensure a flush-mount fit for my 4442 contact chips?

Our precision CNC-milled slot for standard SLE4442 and SLE4428 modules. To achieve a zero-gap fit, we recommend using a high-clarity industrial epoxy adhesive or specialized double-sided tape during the manual mounting process. This ensures the chip remains securely seated and level with the metal surface.

8

Can these black metal cards be used in standard insertion card readers?

Our metal credit card blanks are manufactured to strict ISO CR80 specifications regarding dimensions and thickness. While they provide a highly reliable insertion experience in standard chip readers, the weight and structural integrity of stainless steel may vary from plastic cards. We suggest testing with your specific terminal hardware for high-frequency banking or access applications.

9

Can these cards be used for both contact and contactless payment?

This specific model is designed with a precision CNC slot for contact chips (such as SLE4442 or 4428). It is ideal for contact-based smart systems but does not support internal contactless antennas. For dual-interface cards, please contact our team for other models.

10

What is the benefit of the Hi-Co 2750 Oe magnetic stripe?

The Hi-Co (High Coercivity) stripe is more resistant to damage from external magnetic fields, ensuring your data remains secure and the card lasts longer in high-use environments compared to standard Lo-Co stripes.
