Each Stainless NFC Metal Card is precision-cut from 304 stainless steel with a dedicated recess machined into the card body. An anti-metal NFC tag — constructed with a PET substrate, precision-etched copper coil inlay, and ferrite shielding layer — is embedded into this recess, creating a flush, seamless surface that sits perfectly flat. The solid metal body naturally blocks NFC signals, which means the card is only readable at the tag position — a design that ensures intentional, tamper-proof interaction every time.
This targeted read-zone design delivers reliable tap-to-connect performance at a 1–5 cm range on any NFC-enabled smartphone. The ferrite layer beneath the inlay redirects the electromagnetic field, compensating for the metal backing and enabling stable communication. The result is a card that combines the premium weight, cold-touch feel, and scratch-resistant durability of solid metal with functional NFC capability. Ideal for high-end business cards that share your digital profile with a single tap, VIP membership cards that reflect exclusivity, or access credentials for luxury properties — where the card itself is part of the brand experience.

Frequently Asked Questions
How does NFC work through a solid metal card?
The card has a machined recess that holds an anti-metal NFC tag made of PET + copper coil inlay + ferrite shielding. The ferrite layer redirects the electromagnetic field, compensating for the metal backing behind it. Because the solid metal body blocks NFC signals everywhere else, the card is only readable at the tag position — ensuring intentional, reliable tap-to-connect performance at 1–5 cm.
Which chip should I choose — NTAG213, 215, or 216?
NTAG213 (144 bytes) is ideal for simple URL redirects. NTAG215 (504 bytes) works best for vCard electronic business cards with full contact details. NTAG216 (888 bytes) provides maximum storage for richer content profiles. For most metal NFC business card applications, we recommend NTAG215 or NTAG216.
Can I reprogram the card after receiving it?
Yes. NTAG21x series chips support up to 100,000 write cycles. You can update the stored URL, vCard, or text content at any time using a free NFC writing app on your smartphone. We also offer a permanent lock option if you prefer the data to be read-only after encoding.
Are these cards truly waterproof?
Yes. The 304 stainless steel body is non-porous and fully sealed. The embedded tag is protected within the machined recess, making the card resistant to water, humidity, and everyday wear — far more durable than laminated PVC or paper cards.
What thickness should I choose?
0.8mm is slim and wallet-friendly. 1.0mm is the standard choice balancing feel and portability. 1.2mm delivers a premium heavy feel that luxury brands often prefer for VIP metal membership cards. All three thicknesses work equally well with NFC readers.
What is the minimum order quantity?
We offer flexible MOQ starting from 10 pieces for sample orders. For custom laser-engraved designs, production quantities begin at 100 pieces. Contact us with your artwork for a tailored quotation.
