NFCore is an NFC tag toolkit for iPhone. Read, write and copy your own NFC tags, organize every scan in one library, and lock a tag when it's finished. SCAN & READ Hold your iPhone near a tag to see what's on it: NDEF records, tag type, UID, memory size and technology details. Every scan is saved to your library automatically. WRITE Write nine record types: text, links, Wi-Fi networks, phone numbers, email, SMS, contact cards (vCard), locations and custom external records. Start from a built-in template or save your own for repeat use. COPY YOUR OWN TAGS Back up a tag you own and write its data to a blank tag in two taps (the Clone Tag tool in the app). Handy for a spare of your Wi-Fi tag, smart home tag or business card. TOOLS • Tag Inspector: detailed technical information for a tag • Memory Dump: view and edit raw memory pages in hex and ASCII • Command Console: send raw commands for MIFARE Ultralight / NTAG, ISO 7816, ISO 15693 and FeliCa tags, for developers working with NFC hardware • Batch Write: write the same data to many tags, with progress tracking • Tag Lock: make a tag permanently read-only so nobody can overwrite it (this can't be undone) • Erase: clear a tag so you can reuse it • Emergency Info: write medical details and emergency contacts to a tag for first responders TAG LIBRARY Search by name, type or UID, mark favorites and group tags into folders. Export your tags as JSON or CSV to back up your library or share a setup with your team. WRITE VERIFICATION NFCore reads each tag back after writing to confirm the data is correct. You can turn this off in Settings. TAG COMPATIBILITY GUIDE A built-in reference that shows which tag types support which features, such as memory size and locking, so you can pick the right tag for the job.
