Everything happens on your phone, with no account and no internet access.

READ ANY TAG
• Chip model (NTAG213/215/216, MIFARE Ultralight, MIFARE Classic and more), NFC Forum type and UID
• Memory used and total, whether the tag is writable or can be locked
• Every record decoded: links, text, phone numbers, SMS, email, locations, Wi-Fi, contacts, app launch, smart posters
• Act on it right away: open a link, call, join a Wi-Fi network, add a contact, open an app, or copy

WRITE TAGS
• Nine record types: text, link, phone, SMS, email, Wi-Fi, contact, location and "open an app"
• Combine several records on one tag
• See the size in bytes before you write, with a reminder of common tag capacities
• Blank tags are formatted automatically, and every write is read back to check it

WI-FI TAGS
• Write your network name and password once; guests just tap their phone to join
• Reading a Wi-Fi tag opens the system "save network" screen on Android 11 and later

TOOLS
• Copy a tag to one or many other tags
• Erase a tag so it can be reused
• Lock a tag permanently (with a clear double confirmation)

HISTORY
• Every tag you read is kept on your phone, so you can look at it again or write it to another tag
• Turn history off or clear it at any time; it is never included in cloud backups

PRIVATE BY DESIGN
• Tags are read and written on your phone only
• No internet access, no account, no ads
• Only the NFC permission

Good to know: access cards, transit cards and bank cards are encrypted, so no phone app can copy or write them. When you scan one, this app tells you what it looks like and shows its type and UID. The first time you open the app, a short three-step guide shows where to hold the tag (often near the camera).
