## FAQ
- Q: Do I need to install an app to scan NFC tags on iPhone?
  A: On iPhone XS/XR and later with iOS 14+, no app is needed for basic NFC tag reading. Hold a compatible NFC tag near the top of your iPhone and iOS will automatically process the NDEF data (open a URL, display a message, etc.). Older models (iPhone 7, 8, X) require an NFC reader app from the App Store.
- Q: Why do my NFC tags work on Android but not iPhone?
  A: Android has broader NFC chip support including MIFARE Classic with Crypto-1, which iPhone does not natively read. If your tags use MIFARE Classic chips, they will scan on most Android devices but fail on iPhone. Switch to NTAG 213/215/216 or MIFARE Ultralight chips for cross-platform compatibility.
- Q: Where exactly is the NFC antenna on an iPhone?
  A: The NFC antenna is located at the very top of the iPhone, behind the screen near the front-facing camera and notch/Dynamic Island area. For best results, hold the NFC tag flat against the top 2 cm of the iPhone screen and wait 1-2 seconds for the phone to detect and process the tag.
- Q: Why does my iPhone scan an NFC tag once but not the second time without restarting?
  A: This is almost always Background Tag Reading filtering out duplicates. iOS suppresses repeated NDEF banners for the same payload from the same tag during a short window (typically a few seconds) so a user holding a phone over a tag does not get spammed with notifications. To force a second read, lock and unlock the phone, move the phone away from the tag for a few seconds, or change the NDEF payload on the tag. If the second tap is from a Shortcuts personal automation, also check Settings → Shortcuts → the automation and make sure 'Run Immediately' or 'Notify When Run' is configured the way you expect — this controls whether the user has to confirm before the action runs.
- Q: Can I use the same NTAG 213 / 215 / 216 stickers across iPhone and Android, or do I need different SKUs?
  A: The same NTAG 213, 215, and 216 stickers work on both iPhone (iOS 14+) and Android (4.0+) and on Windows, macOS, and Linux readers using a USB NFC reader such as the ACR122U. NTAG is part of the NFC Forum Type 2 specification, which is the most widely supported tag family in consumer devices. The only common cross-platform pitfall is MIFARE Classic 1K/4K tags — Android can read them, iPhone cannot. If you want a single SKU for marketing handouts, business cards, smart packaging, or product authentication that has to work on every modern phone, specify NTAG 213 (cheapest, 144 bytes), NTAG 215 (Amiibo-compatible, 504 bytes), NTAG 216 (largest, 888 bytes), or NTAG 424 DNA when you also need cryptographic authentication.
