## FAQ
- Q: How does NFC work through a metal card body?
  A: Two engineering options. (1) Ferrite-backed on-metal inlay: a 30–100 μm NiZn or MnZn ferrite film between the NFC antenna and the metal redirects 13.56 MHz magnetic flux around the metal, so the antenna couples cleanly to the reader at 1–3 cm. (2) Antenna-window cutout: a precision-milled thinned slot on the rear face lets the reader see through the window. ProudTek defaults to ferrite-backed because it gives better tap range; window-cutout is available for higher-volume cost-sensitive runs.
- Q: Why fibre laser and not CO2?
  A: Fibre laser at 1064 nm matches the absorption band of stainless steel, brass and anodised coatings — producing laser-annealing on stainless (dark marks from controlled oxidation) or deep engraving on brass (recessed marks that hold colour-fill). CO2 lasers at 10.6 μm are optimal for wood, plastic and glass but reflect off polished metal and produce inconsistent marks. The wavelength choice reverses for the wooden-card SKU where CO2 is correct.
- Q: Can I update the NFC data after the card is produced?
  A: Yes, the NTAG chip is reprogrammable unless write-locked at factory. Use NFC Tools or NXP TagWriter to rewrite the NDEF payload. For flexibility, point the card at a URI (Apple Business Connect, Google Business Profile, Calendly, Linktree, Blinq or Popl) and update the landing page rather than the chip. NTAG424 DNA is the exception — premium anti-cloning chips are typically locked to a tamper-evident configuration at factory.
- Q: What substrate should I pick — 316L stainless, brass or PVD-black?
  A: 316L brushed stainless is the default executive-networking choice: neutral, clean, corrosion-resistant. Brass warms to a patina over 6–12 months — favoured for wealth-management and private-banking advisors and for executives who want the card to age visibly. PVD-black is the deep-matte luxury choice — brand ambassadors, creative directors and luxury-boutique founders. All three use the same ferrite-backed inlay and the same NDEF payload.
- Q: What is the minimum order and lead time?
  A: MOQ 50 per design for a single logo / single chip configuration. Per-person individual engraving for C-suite runs is available at MOQ 25 with a small-batch pricing tier. Lead time is 10–15 business days from artwork approval. Rush production (7 business days) is available for a surcharge. Physical proof samples with your design ship in 5–7 business days before production starts.
