About this app

Turn NFC tags into useful shortcuts for your home, shop or workspace.

Douvi NFC is an NFC reader and writer for Android. Read compatible tags, create links and contact records, and check the stored data after writing.

READ AND WRITE NFC TAGS
Create tags for websites, digital menus, Google review pages, social profiles, phone numbers, email, text notes and locations. Store contact details as a vCard.

Choose what your tag should do, enter the details, then hold a compatible writable tag near your phone.

WRITE AND VERIFY
After writing, Douvi reads the tag again and compares the stored content with what you intended to save. Get a clear verification result instead of guessing whether the write worked.

Overwrite prompts and capacity checks help you avoid replacing existing content unintentionally or writing more data than a tag can hold.

NFC DOCTOR
Check whether your phone has NFC, whether NFC is enabled, and whether the reader is ready. Scan a tag to inspect its writable status, NDEF information and available capacity where supported.

SAVED TEMPLATES
Reuse your recent templates without entering the same details again. The free version gives you access to your five most recent saved templates.

DOUVI NFC PRO
An optional one-time purchase unlocks:

* Your full local template library
* Copying compatible NDEF content to another tag
* Batch Writer for writing one template to multiple tags, one tag at a time
* Template import and export
* Custom MIME and External Type NDEF records
* Expert tools for detailed NFC and NDEF inspection

Core reading, standard writing, verification and NFC Doctor remain available without Pro. No subscription is required for the Pro upgrade.

PRIVATE BY DESIGN
Core NFC operations work locally on your device. Saved templates stay in the app's local storage, and you choose where exported files are saved.

No Douvi account is required. The app contains no ads. Google Play handles Pro purchases and purchase restoration.

10 LANGUAGES
English, Spanish, Brazilian Portuguese, German, French, Japanese, Korean, Simplified Chinese, Traditional Chinese and Vietnamese.

BEFORE YOU START
An NFC-enabled Android phone and compatible NFC tags are required. Physical tags are not included. Available operations depend on your phone, the tag's technology, capacity and protection settings.

Douvi NFC does not clone payment cards or protected access credentials.

Read. Write. Verify.
