Understanding Blank 4442/4428 chip slot metal card vs Blank Dual Interface Metal Card
Metal smart cards have become a symbol of luxury, durability, and innovation. From VIP access to secure payments, they are widely used across industries.
But many buyers often ask:
What is a blank metal card with a 4442/4428 chip slot?
How does a dual interface metal card differ?
Can these cards be used in ATMs?
This guide explains the differences, applications, and ATM compatibility in a clear and easy-to-understand way.
What Is a Blank Metal Card with a 4442/4428 Chip Slot?
A blank metal card with a 4442 or 4428 chip slot is a semi-finished card designed for embedding memory chips (SLE4442 or SLE4428).
These chips are not EMV-certified, meaning they can store data but cannot handle financial transactions.
Common Uses
Access control – offices, hotels, or clubs
Membership programs – VIP cards, luxury club passes
Gift or loyalty cards – premium brand experiences
Data storage and educational demos
The metal exterior provides a premium look and durability.
ATM Compatibility
Cannot be used in ATMs or banking systems.
Memory chips like SLE4442/4428 are not compatible with EMV protocols, which are required for financial transactions.
What Is a Dual Interface Metal Card?
A dual interface metal card supports both contact and contactless interactions:
Contact interface – the traditional chip for inserting into terminals
Contactless interface – NFC-enabled for tap-to-pay or access
These cards combine premium metal design with advanced functionality, making them popular for banks and fintech companies.
Common Uses
Bank and payment cards (credit/debit with EMV chips)
Corporate or government ID cards
Luxury membership or VIP cards
Secure access or authentication systems
Technology Inside
Dual interface metal cards can embed EMV-certified microcontroller chips, such as:
NXP JCOP 4
Infineon SLE78 series
STMicroelectronics ST31
Samsung ARTIK secure module
These chips allow the card to work securely with ATMs and POS systems.
Are Dual Interface Metal Cards ATM Compatible?
Yes — but only with EMV-certified chips.
Dual interface metal cards with EMV chips can be used for ATM withdrawals, POS payments, and secure identity verification.
If the card only has a basic NFC chip without EMV certification, it cannot be used in ATMs.

Why Metal Smart Cards Are Growing in Popularity
Metal smart cards are not only functional but make a strong first impression.
Whether for luxury branding, corporate identity, or secure transactions, a dual interface metal card or blank metal card can deliver premium experience and high-end feel.
For businesses looking to source these cards, working with a reliable metal card manufacturer ensures high-quality metal cards with customizable finishes, such as laser engraving, anodized color, or embossed logos.
Final Thought
Choosing between a blank metal card and a dual interface metal card depends on your goal:
For non-financial applications like access control, memberships, or demo purposes → choose a blank metal card.
For financial, secure, or multi-functional applications → choose a dual interface metal card with EMV-certified chips.
A professional metal card manufacturer can provide both options, helping businesses combine style, security, and functionality in a single card.
