Frequently Asked Questions
What is NFC Tool?
NFC Tool is a full-featured NFC tag reader, writer, and manager for iOS and Android. Tap any NFC tag to instantly read its contents, or write your own data including URLs, plain text, vCard contacts, WiFi credentials, phone numbers, and email addresses.
What types of data can I write to an NFC tag?
NFC Tool supports writing URLs, plain text, vCard contacts, WiFi network credentials, phone numbers, and email addresses. Simply select the data type, fill in the details, and tap your tag to write.
What is Tag Info and what does it show?
Tag Info displays detailed technical information about any NFC tag you scan, including the tag type (e.g., NTAG213, NTAG215, MIFARE), UID, memory size, technology, and whether the tag is read-only or writable.
Can I erase or lock an NFC tag?
Yes. NFC Tool includes dedicated Erase and Format tools to wipe tag contents, and a Lock feature to make a tag permanently read-only. Locking is irreversible, so the app asks for confirmation before proceeding.
Does NFC Tool store my data or track me?
Your tag data stays on your device. The contents of the tags you read and write, what you enter to write them, and your scan history are stored only on your phone and are never sent to us. The app uses Google Firebase for usage statistics and crash reports, which never include tag contents or anything you type. The free version shows ads from Google AdMob, which may use your device's advertising identifier to personalise and measure ads: on iOS only if you allow tracking, in the EEA, UK and Switzerland only with your consent, and on Android you can reset or delete the advertising ID in your device settings. NFC Tool Pro removes ads. The privacy policy has the details.
What is the History feature?
Every tag you scan is automatically saved to your local history with a timestamp. You can search, filter, and export your scan history for record-keeping or sharing.
Is NFC Tool free to use?
NFC Tool is free to download, and its core reading and writing features are free to use with ads. An optional NFC Tool Pro subscription (weekly or yearly) unlocks more write types, the advanced tools, your full scan history and export, and removes ads.
How many languages does NFC Tool support?
NFC Tool supports 73 languages including English, Spanish, French, German, Portuguese, Turkish, Arabic, Hindi, Japanese, Korean, and Chinese - making it accessible to users worldwide.
