## FAQ
- Q: Do NFC business cards work on iPhones without an app?
  A: Yes on iPhone XS and newer (September 2018 release onwards). Background tag reading shipped in iOS 13 and works for any URL using the allow-listed URL schemes (https, tel, sms, mailto, geo, facetime, x-callback-url). The user taps the card to the top of the phone and the URL preview appears at the lock screen or banner. iPhone 7, 8 and X have NFC hardware but require the user to open Control Center and tap the NFC Tag Reader icon, then scan. iPhone 6S and earlier have no NFC support — cards do not work at all. Android phones with NFC (universal since 2011) have always read tags through OS-level NDEF dispatch.
- Q: Which NTAG chip should I pick for my programme?
  A: NTAG213 (144 B) — URL-only programmes (tap-to-LinkedIn, tap-to-Calendly). Cheapest. NTAG215 (504 B) — embedded vCard plus URL fallback. Standard for executive cards. NTAG216 (888 B) — full vCard 4.0 with multi-language and multi-line fields. Best for international or corporate rollouts. NTAG 424 DNA — anti-clone authentication with SUN unique-URL per tap. Use for luxury, executive or high-value-relationship cards where clone detection matters. Most team rollouts converge on NTAG216 + premium material as the default; NTAG 424 DNA is reserved for executive / luxury tier.
- Q: Will metal NFC cards work reliably on iPhones?
  A: Yes, but only with a ferrite isolator behind the chip and at roughly half the read distance of an equivalent PVC card. Without the ferrite layer, the metal substrate produces a parasitic eddy current that detunes the antenna and kills the read. Read distance on a brushed-aluminum NTAG216 card with ferrite isolator is typically 4–6 cm vs 8–10 cm on PVC. Cost premium is roughly 4–8× PVC. Metal works well for executive cards where the recipient is intentional about the tap; less well for high-volume events where the recipient is fumbling. Pilot the specific finish (brushed, mirror, etched) on the actual chip variant before scaling.
- Q: What happened with Linq sunsetting its NFC business-card platform?
  A: In early 2025 Linq exited the digital business-card business and pivoted to AI messaging APIs. Every Linq-issued card pointed at a Linq-controlled domain that subsequently stopped routing the way customers expected. Customers either re-ordered cards from a different vendor or accepted that their existing card stock had a degraded routing layer. The procurement lesson: every SaaS routing platform is one strategic pivot away from orphaning your card inventory. OEM-direct cards pointing at your own company domain do not have this risk — the URL routing layer is under your control, not a vendor's. This is the single largest reason a corporate rollout should evaluate self-hosted URL routing alongside or instead of a SaaS platform.
- Q: Should I use a SaaS platform like Popl or V1CE, or self-host the URL?
  A: Depends on programme scale and engineering capability. SaaS platforms (Linq, Popl, V1CE, Mobilo, Wave, Blinq, TAPiTAG) provide turnkey landing pages, lead capture forms, per-card analytics and (often) CRM integration. Cost is $6.99–$15.99 per user per month for full features — $17K–$38K per year at 200-employee scale. Self-hosted URLs on your own domain cost ~zero per card per year and survive any vendor pivot, but require engineering work to build the landing page, the analytics stack and any lead-capture flow. The hybrid path (static URL on your domain that redirects through a self-hosted analytics endpoint) is the most common enterprise approach. For solo cards or teams under 10, SaaS turnkey is fine; for 100+ corporate rollouts, self-host.
- Q: Can I update the URL after the card is printed?
  A: Yes if the chip is rewritable (NTAG213, 215, 216) and not write-locked. Use NXP TagWriter, NFC Tools or any NDEF-capable encoder to re-write the URI record. Programme caveat: rewriting requires physical access to the card, so for a deployed corporate rollout you can't update 500 cards by clicking a button — you'd need to re-issue or physically re-program. The pragmatic solution: program a stable URL on the card (`https://yourcompany.com/contact/{name}`) and use server-side redirect rules to change the actual destination per campaign / per A/B test. The card never needs to change once issued.
- Q: What is NTAG 424 DNA SUN authentication and when is it worth the premium?
  A: NTAG 424 DNA (NXP NT4H2421Gx) is a security-tier NFC chip with the SUN (Secure Unique NFC) feature. Each tap generates a unique URL signed with AES-CMAC. A genuine card produces a sequence of URLs the server can validate against the AES key; a cloned card cannot reproduce the cryptographic signature. The chip costs ~$0.40–0.80 vs $0.05–0.10 for NTAG213 — the premium pays back only when authentication actually matters: luxury executive cards, anti-counterfeit collector items, pharmaceutical / electronics provenance, EU Digital Product Passport compliance. SUN encoding requires AES key injection at programming time; key management (HSM, cloud KMS, split-key custody) is part of the programme design.
- Q: What sustainability claims actually pass enterprise audit?
  A: Four certifications matter for chain procurement RFP audits: (1) Forest Stewardship Council chain-of-custody (FSC-STD-40-004) for wood and bamboo cards — cite the FSC certification number, not just "sustainably sourced"; (2) Global Recycled Standard (GRS) ≥50% recycled content for recycled-PVC claims; (3) TÜV Austria OK biobased (EN 16640) for PLA bio-based claims; (4) BPI ASTM D6868 / ASTM D6400 compostability for biodegradable claims. Marketing language like "eco-friendly" or "sustainable" without a certification body backing the claim does not pass audit; brand procurement teams now ask for the cert number specifically.
- Q: Do NFC business cards support multi-language vCard?
  A: Yes via RFC 6350 vCard 4.0. UTF-8 character set (Section 3.1) supports any non-Latin script (CJK, Cyrillic, Arabic). The `LANG` parameter (Section 5.10) tags individual fields with a locale, so a single vCard can carry name + title + company in multiple languages. NTAG216 (888 B) is the practical chip for multi-language vCard; NTAG215 (504 B) usually fits 2 languages; NTAG213 (144 B) is URL-only. For international team rollouts where the recipient might be in any of 5+ regions, NTAG216 with multi-LANG vCard is the standard configuration.
