NFCore - NFC Tag Reader Writer

NFCore gives you complete control over NFC tags on your Android device. Whether you're a developer, hobbyist, IT professional, or just someone who wants to get more out of NFC, this app provides every tool you need to read, write, clone, inspect, and emulate tags — all from one place.

SCAN & READ

Tap any NFC tag to instantly read its contents. NFCore supports all major tag types including NTAG213, NTAG215, NTAG216, MIFARE Classic, MIFARE Ultralight, MIFARE DESFire, ISO 14443, ISO 15693, and FeliCa. View NDEF records, raw memory data, and detailed tag metadata including UID, ATQA, SAK, technology type, memory capacity, and read-only status. Every tag you scan is saved to your local library so you can reference it later.

WRITE

Write text, URLs, phone numbers, emails, SMS messages, geographic locations, WiFi network configurations, vCards, and custom NDEF records to any writable NFC tag. Choose from built-in templates for common use cases or create your own custom templates for quick repeated writes. NFCore handles the formatting and encoding automatically — just pick a record type, enter your data, and tap a tag.

CLONE & BACKUP

Copy the full contents of one NFC tag to another with a single tap. Useful for creating backups of important tags or duplicating configurations across multiple tags. All cloned data is stored locally in your tag library with support for custom names, folders, color labels, and notes so you can stay organized.

INSPECT & DEBUG

Dive deep into any tag with the full memory dump inspector. View raw hex data page by page and examine exactly what's stored on a tag at the byte level. Send custom APDU commands through the built-in NFC console with support for multiple tag technologies. See command history, response codes, and timing data. Perfect for NFC development, protocol debugging, security research, and learning how NFC works under the hood.

EMV CARD READER

Read publicly available data from contactless payment cards including card type, application label, expiration date, and masked card number. NFCore only reads data that the card broadcasts publicly over the contactless interface — the same data any NFC-enabled terminal can see. All data stays in memory only and is never stored or transmitted anywhere. Built strictly for educational and diagnostic purposes.

TAG EMULATION (HCE)

Turn your Android phone into a virtual NFC tag using Host Card Emulation. Add text and URL records, toggle emulation on, and let any NFC reader scan your device as if it were a physical tag. Runs as a foreground service with a persistent notification so you always know when emulation is active. Emulates standard NDEF tags only — no payment cards, access credentials, or transit passes.

BATCH WRITE

Need to program dozens of tags with the same data? Set up your records once, set a target count, and write them to as many tags as you want — one after another. NFCore tracks your progress with a live counter showing successful and failed writes so you can keep moving without losing count.

EMERGENCY MEDICAL PROFILE

Create a personal emergency medical profile with your name, date of birth, blood type, allergies, current medications, medical conditions, and up to three emergency contacts with phone numbers. Write this profile to any NFC tag and attach it to a keychain, wristband, or wallet card. First responders or bystanders can scan the tag with any NFC-enabled phone to access your critical health information — no app required on their end.
