NFC Tools – Read and Write NFC Tags on Android

NFC Tools turns your phone into a powerful NFC reader, writer, and automation tool that lets you read, write, program, and manage NFC tags with just a tap.

Developed by wakdev, NFC Tools versatile utility app has earned a 4.6 star rating from 58,900 ratings on the App Store and over 10 million downloads across platforms. The app is available on Android, iOS, Desktop (Mac with NFC reader), and Flipper Zero, with a file size optimized for mobile devices and rated for ages 4 and up.

What Is NFC Tools?

NFC Tools is a versatile utility app that lets you read, write, and program tasks on NFC tags and other compatible NFC chips, with a simple and intuitive interface for recording standard information (text, URLs, contacts, social profiles, locations) and automating device actions (Bluetooth toggle, alarm setting, volume control, WiFi sharing) that were once boringly repetitive. The app is available on Android, iOS, Desktop, and Flipper Zero, making it one of the most comprehensive NFC tools on the market.

The core functionality involves passing your device near an NFC chip to interact with its content. The “Read” section displays detailed tag information (maker, type, norm, technology, serial number, size, writability, NDEF data). The “Write” section allows you to record standardized data (text, link, email, phone, address, geolocation, WiFi, Bluetooth, social profiles, Bitcoin, etc.) compatible with any NFC device. The app goes further to program tasks on NFC tags for automation via the companion NFC Tasks app.

Read, Write, and Program NFC Tags

When you pass your device near an NFC tag, NFC Tools reads everything about it. You see the manufacturer, tag type, NFC standard, technology, serial number, memory size, and whether the tag is writable. The app also displays all NDEF data on the tag in a scrollable list with per-record detail views.

Writing is equally straightforward. You can write text, URLs, contacts (vCards), phone numbers, SMS messages, email addresses, WiFi configurations, Bluetooth pairings, geolocation coordinates, social profiles, Bitcoin addresses, Facetime contacts, and search engine shortcuts. The app also supports custom data records for proprietary applications. Everything is standardized NDEF content, so it works with any NFC device.

For automation, the companion NFC Tasks app (Android only) lets you program tags to toggle Bluetooth, set alarms, control volume, share WiFi and more. Tasks are categorized for easy selection, making automation accessible even for beginners.

Wide Chip Support and Advanced Features

NFC Tools supports a wide array of NFC chip types including NTAG (203, 210, 212, 213, 215, 216, 413 DNA, 424 DNA), Ultralight, Mifare Classic (1K, 4K), ICODE (SLI, SLIX, SLIX2, SLIX-S, SLIX-L, ICODE 3), DESFire (EV1, EV2, EV3 NDEF), FeliCa, and ISO 14443-3A generic tags. This broad compatibility ensures you can work with almost any NFC hardware.

Can I Write NFC Tags With My Phone?

Yes, you absolutely can write NFC tags with your phone, provided it has NFC hardware. Most modern Android devices come with NFC built-in, and you can use apps like NFC Tools to write data to blank tags.

The process is straightforward. You need three things: an NFC enabled phone, blank writable NFC tags (like NTAG213 or NTAG216) and an NFC writing app . NFC Tools is one of the most popular and well-regarded options for this purpose .

The writing process takes just a few steps. First, enable NFC in your phone’s settings. Then open the NFC Tools app, select the “Write” section, choose the type of data you want to write (URL, text, contact, WiFi, etc.), enter the information, and hold your phone near the tag when prompted.

What can you write? You can write URLs, plain text, contact information (vCards), WiFi network credentials, phone numbers, email addresses, geolocation data, social media profiles and even automation tasks via the companion NFC Tasks app. The app supports standardized NDEF records, which means anything you write will work with any other NFC compatible device.

Not all phones support NFC writing. If your phone does not have NFC hardware or you are unsure, check your device settings for an NFC option. Older phones or budget models may lack this feature.

NFC Tools Tips For Getting Started

Getting started with NFC Tools is straightforward, but a few smart choices early on will save you time and help you get the most out of the app. Here is what to focus on first.

Beginner Advice

Start with simple NFC tags (e.g., NTAG213). Do not try to program complex tags immediately. Start with a basic NTAG213, which is widely available and affordable. These tags are compatible with most phones and have enough memory for text, URLs, and basic automation. Once you understand how they work, you can explore more advanced tags like NTAG215, NTAG216, or ICODE.

Read tag info before writing. Before you write anything to a tag, read it first. Tap the “Read” section and hold your phone near the tag. Check the manufacturer, tag type, serial number, memory size, and writability. This tells you what you are working with and whether the tag has any existing data you might overwrite. A quick read prevents accidental data loss.

Write simple text or URL for testing. Your first write should be something simple. Write a plain text message like “Hello, NFC!” or a URL like your favorite website. These are the easiest records to create and test. Once you confirm they work, you can move on to more complex records like contacts, WiFi, or automation tasks.

Test with another NFC device for compatibility. Just because your phone can read a tag does not mean every phone can. Test your written tag with another NFC-enabled device. This confirms your tag works across devices and helps you identify compatibility issues early.

Use NFC Tasks for automation (Android only). If you are on Android, download the NFC Tasks companion app. This is where the real power of NFC Tools shines. You can program tags to toggle Bluetooth, set alarms, control volume, share WiFi, and more. Tasks are categorized for easy selection, so you can find what you need quickly.

Start with simple Bluetooth toggle task. Your first automation task should be simple. Program a tag to toggle Bluetooth on and off. Place it near your desk or car. When you tap it, Bluetooth changes state. This gives you immediate, practical value and teaches you how task programming works.

Backup tags with copy/clone functionality. Before you modify a tag, back it up. Use the copy or clone functionality to save its contents. This way, if something goes wrong, you can restore the tag to its original state. Backups are especially important for tags with unique data like serial numbers or cryptographic keys.

Organize tags into groups for better management. As you collect more tags, organization becomes important. Create groups for different projects or use cases. Move tags between groups as your needs change. This keeps your tag library manageable and makes it easy to find what you need.

Import/export NFC commands for sharing and backup. The import/export functionality lets you share commands with others or backup your work. Export commands to a file and save it somewhere safe. Share it with colleagues or friends who also use NFC Tools. This is especially useful for professional workflows.

Read knowledge base articles and how-to guides. The wakdev website has a comprehensive knowledge base with articles, how-to guides, videos, and troubleshooting. Take advantage of it. Reading the documentation before you start saves time and prevents common mistakes.

Advanced Strategy

Master dynamic variables for adaptive tags. Dynamic variables like {TAG-ID}, {TAG-NAME} and {DATETIME} let you create adaptive tags that change behavior based on who scans them or when . For example, a tag that logs the time and tag ID every time it is scanned. This is powerful for attendance tracking, inventory management, and personalized experiences.

Optimize NDEF records for cross-device compatibility. Not all NFC readers handle NDEF records the same way. Keep records simple and well-structured. Use standard record types (text, URI, vCard) whenever possible. Avoid custom formats that might not be recognized by other devices.

Develop complex automation tasks via NFC Tasks. As you grow comfortable, build more complex automation workflows. Program a tag to toggle Bluetooth, set an alarm, and adjust volume in one tap. Combine tasks to create powerful automations. The only limit is what you can imagine.

Set up professional NFC workflows for digital marketing. NFC tags are powerful tools for digital marketing. Program tags with short URLs (using Unit.Link) and place them on posters, product packaging, or business cards. Track engagement with analytics. Create social media profiles that link to all your channels. The possibilities are vast.

Use Unit.Link extensively for short URLs and analytics. Unit.Link integration gives you short, trackable URLs. Use it for every URL you write to an NFC tag. The analytics tell you how many people scanned the tag, when, and from where. This data is invaluable for marketing campaigns.

Customize with branding using custom keychains. For professional use, consider custom keychains or NFC.CARDS with your branding. These make great giveaways and are more durable than sticker tags. They also look more professional and create a stronger impression.

Integrate Bitcoin address storage for cryptocurrency. If you accept cryptocurrency payments, program an NFC tag with your Bitcoin address. Tapping the tag pastes the address into the user’s wallet app. This is faster and less error prone than typing or scanning QR codes.

Use Facetime and Facetime Audio for iOS contacts. For iOS users, Facetime records let you share contact information that opens directly in Facetime. This is a convenient way to share your contact details with other iPhone users. Tap the tag, and they can instantly call or message you.

Develop custom data records for proprietary applications. If you are building proprietary applications, create custom data records that your app can read. This lets you store application specific data on NFC tags without interfering with standard NDEF records. Your app reads your custom records, and other NFC readers ignore them.

Use erase/lock/format strategically for security. Erase sensitive data from tags before discarding them. Lock tags that should be read only to prevent accidental or malicious overwrites. Format tags to clear all memory when you need a fresh start. These operations are permanent, so use them carefully.
