NFC Kit - Read Write Tags

NFC Kit reads, writes, erases and protects NFC tags. No ads, no account.

READ
• UID, chip type, capacity and tag status at a glance
• Decodes every NDEF record type: link, text, Wi-Fi, contact card, phone, email, message, coordinates, MIME
• Full memory view in HEX, ASCII or binary with colour-coded regions
• Export the memory as .txt or .bin

WRITE
• Ten content types, each with its own form
• Capacity is checked before writing, and the tag is read back and compared byte by byte
• Edit, reorder and delete individual records
• Erase the NDEF content or reformat the tag

TAG SECURITY (NTAG213/215/216, Ultralight EV1)
• Set and remove the PWD/PACK password
• Choose the first protected page (AUTH0), block reads too (PROT), limit attempts (AUTHLIM)
• Lock a tag permanently to read-only, behind a two-step confirmation
• Passwords live in the Keychain and travel through iCloud Keychain, end-to-end encrypted

HISTORY AND AUTOMATION
• Every scan is saved; search, star and give tags a nickname
• One-tap templates, batch writing with a counter and a per-tag error log
• Copy content to another tag, back a tag up to a file, export and import history as JSON
• Shortcuts actions for Siri and automations

LIFETIME UNLOCK - $4.99, ONE-TIME, NO SUBSCRIPTION
These three features require the purchase; everything else in the app stays free forever:
• iCloud backup of the tag history
• Export and import of tag data
• Reading and editing raw tag memory
The purchase restores on every device on the same Apple Account, and the app has a Restore Purchases button.

WHAT iOS DOES NOT ALLOW - SAID UP FRONT
iOS does not let apps read MIFARE Classic data (only the UID), copy a UID onto another tag, emulate a tag, or join Wi-Fi automatically from a tag. These are system limits that no app gets past. The app includes a page explaining all of them.

Requires iOS 18, so an iPhone XR or newer.
