NFCore - NFC Tag Reader Writer

NFCore gives you everything you need to work with NFC tags on your iPhone.

SCAN & READ
Instantly read any NFC tag — NDEF records, tag type, UID, memory size, and technology details. Tags are auto-saved to your library for easy access later.

WRITE
Write text, URLs, WiFi credentials, contacts (vCard), phone numbers, email links, and more. Use built-in templates or create your own custom templates for repeat use.

PRO TOOLS
• Tag Inspector — Deep dive into tag metadata and full technical specs
• Memory Dump — View and edit raw tag memory byte-by-byte
• Command Console — Send raw ISO 7816, ISO 15693, and NFC-A commands directly
• Clone Tag — Copy one tag's data to another
• Batch Write — Write the same data to multiple tags in sequence
• Tag Lock — Permanently or soft-lock tags to prevent modification
• Emergency Info — Write medical and emergency contact info to an NFC tag

TAG LIBRARY
Every scan is auto-saved. Organize with folders, search by name, type, or UID. Export tags as JSON or CSV. View scan history with timestamps and tag details at a glance.

TEMPLATES
Start from pre-built templates for WiFi sharing, contact cards, website links, phone calls, SMS messages, email links, and more. Save your own custom templates for repeat use. Perfect for writing the same data to multiple tags quickly.

DESIGNED FOR iOS
Native app built for iPhone. Supports Dynamic Type for adjustable text sizes, full VoiceOver accessibility, dark mode, and Siri Shortcuts. Localized in 35 languages including Arabic, Chinese, Japanese, Korean, French, German, Spanish, and many more.

NFCore Pro is a one-time purchase that unlocks all pro tools, unlimited tag saves, and unlimited templates. No subscriptions. Pay once, own it forever.

COMPATIBILITY
Works with all NFC tag types supported by iPhone: NDEF (Types 1–5), NTAG, Ultralight, DESFire, ISO 14443, ISO 15693, and FeliCa. Supports iPhone 7 and later running iOS 17.6 or newer.

SIRI SHORTCUTS
Scan tags hands-free with Siri. Just say "Scan an NFC tag with NFCore" to start a scan instantly. Also supports viewing your saved tag library via Siri.

PRIVACY FIRST
All tag data stays on your device. No accounts required, no cloud sync, no analytics, no tracking. Your NFC data is yours and never leaves your iPhone.

One app. Every NFC tool you need.

EXPORT & SHARE
Export saved tags as JSON or CSV. Share data with teammates, back up your library, or transfer tag information between devices. Great for documenting tag configurations and sharing with your team.

WRITE VERIFICATION
Reads back every tag after writing to confirm data integrity. Toggle this on or off in settings. Never wonder if a write actually worked.
