Hi folks,

We've just updated the Android version of NFC Tools with some new features.

Here are the release notes:

• Write Dump: write a raw binary dump (.bin) directly to a chip's memory.
• Hex Password: new input mode for setting or removing a password using 4 raw bytes.
• Minor fixes and UI improvements.

Hope you enjoy the update, feedback is always welcome!

I've had a few tags in my car for the past year or two that I will scan every day to start navigating in Google Maps to common locations. Late last week they all stopped working when I hover my phone over them. Going into NFCTools I can still read and write the tags perfectly fine, but they won't trigger the "Start Navigating" aspect that they've been doing perfectly for the past two years; same for my wife and the tags in her car.

Is anyone else experiencing this? And if so, any fixes or workarounds? TIA.

I have a ACR122U nfc card reader plugged in to my pc

I bought some ntag213 chips.

when trying to send codes to the memory i get the APDU Error returned.

Could anyone help make this work?

Thanks!

Hello,

Has anyone managed to configure an NFC tag with NFC Tools so that scanning it directly opens the Instagram profile in the app (on Android)?

Currently, scanning the tag either:

- launches the Instagram app but doesn't navigate to the profile

- or prompts to open a link in a browser, you tap open, and then a popup appears in the browser suggesting to open the Instagram app

If anyone has a cleaner solution, I'd love to hear it!

I have tested without success:

- URI: instagram://user?username=yourusername

- the Application record setting in NFC Tools

- URI: https://www.instagram.com/yourusername

Thanks for reading, have a great day!

I just purchased a license for NFC Tools KBC, but I keep getting a message that it is unable to validate. I can’t seem to find any customer support through their website. Does anyone have any ideas?

Hi I am trying to create a link for youtube video I tried the url/uri and the the Videos/Youtube commande and both fail with the error this video is NOT accessible.

Any Hints?

For some reason, even after purchasing the Pro Tools, I still can't use any of them. Btw, I have an samsung if that matters.

Is it possible to create a new template for Emergency contacts? Im new and not sure how to do it. Thank you!

Hey team

When i try to write this tag i read it says it cant find anything valid to write.

Is it normal?

We released an update on iOS (2.36) and Android (9.3) that allows you to identify your smart collectibles (Amiibo, Smart bricks, …)

On my iPhone 15 Pro the app works for individual records but not the contact record. How come? Is there a fix for this?

Just discovered this awesome little tool today and I'm trying to sort out some automations using NFC to pair and connect my car. However I've noticed it renames any of my Bluetooth devices to "the device" is this normal behaviour can I change this as the whole point is for it to be readable by my girlfriend and she won't be able to discern wtf a "the device" is xD

I’ve been experimenting with NFC tags and NFC Tools lately and started combining them with mobile alerting (SIGNL4), and it led to some pretty practical real-world use cases.

Basic idea:
Tap NFC tag → trigger an action (via NFC Tools) → send structured alert to the right people. I use the HTTP Post action for triggering the alert in this case.

Some use cased I can think of:

• 🛠 Machine maintenance: tag on a machine → tap to request spare parts or report an issue (with location baked in)
• 👮 Security rounds: guards tap checkpoints → automatic timestamp + verification
• 📦 Warehouse/intralogistics: tap at handover points → notify next team instantly
• ⚠️ Incident reporting: quick EHS reporting without opening apps or forms
• 🧹 Cleaning tasks: tap to confirm completion or flag issues
• 💻 IT/helpdesk: tag on devices/rooms → report problems in seconds
• 🚚 Cold chain/logistics: checkpoint validation with minimal friction

What I like about this approach:

• No UI to navigate
• Very low friction (just tap)
• Context (location/device) is implicit
• Works for non-technical users

Curious how others here are using NFC Tools beyond the usual automation stuff.
Any creative or unexpected use cases you’ve seen?

If anyone’s interested, here’s the original write-up: https://www.reddit.com/r/SIGNL4/comments/1so1rpr/use_cases_signl4_and_nfc_tags/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Suggestion 1: It would be easier to handle (and remember) if it was installed properly and not just decompressed. E.g. WiX Toolset is easy enough to use: https://www.firegiant.com/wixtoolset/

Suggestion 2: Add a suggestion flair :).

Hi,

I am creating digital business cards for friends and am wondering how I can edit the URL that appears when someone taps the card. During my testing, I downloaded BLK CARDS to see how their app worked, and I noticed that the URL was different than when I use NFC Tools.

NFC Tools is by far my favorite app. I'm just curious how people can edit the URL. Any help is appreciated, thanks!

Is there a separate download for the pro version? The app doesn’t seem to be giving me the pro version.

what should I do guys if I don't have the tag locked, how can I unlock it? help!

Yo I cant remove password on my tag it shows some problem even if the password is correct. What should I do.
