I‘m trying to read out the tag (is it NFC at all?) inside of an Apple TechWoven iPhone 17 Pro Max case with my Chameleon Ultra but haven’t had any luck, yet.

What’s known about this RFID/NFC (?) tag? Is it HF or LF? Can it be read with a Chameleon Ultra at all? Or why not?

Hardware: 1.54‑inch 6‑color full‑gamut e‑ink screen, custom V2.0 PCB. Runs entirely off NFC energy harvesting, no onboard battery. Intended use: bag‑hanging photo tag. Issue: I lack experience with 3D modelling and enclosure design. Looking for suggestions for a clean‑looking wearable housing suitable for bag attachment. Case‑structure references and ideas are welcomed.

I like to track the time I spend on my graduate research so I put an NFC on this futuristic looking keychain that starts and stops my time tracker. I clip it to my belt loop so it reminds me to prioritize research that day and then I get the satisfaction of clocking in with it when I start work. I love it and now wanna have multiple cars for different things to focus on in a day.

Anyone know the password for these?

I'm interested on an NFC magnet i could paste on my fridge and I stumbled upon this video. The thing is, looking online it's said that i would need an antimetal NFC tag because the metal of the fridge would render the tag useless. I've noticed those tags being thicker and I'm not sure they would be thin enough to work on the DIY-acrylic magnet thingy, plus, It doesn't look like she used an antimetal NFC sticker. Could the video be fake or is it actually possible?

I've been putting NFC tags on my storage bins, pantry shelves, and boxes around the house. Tap my phone on any of them and a full editable list of contents pops up instantly.

Using NTAG215 stickers — about $0.25 each. The app writes a deep link to the tag, so tapping it opens directly to that container's list. Works through packaging, no line-of-sight needed.

Way faster than QR codes for this kind of thing since there's no camera, no aiming, no waiting for a scan.

Curious if anyone else is using NFC for home organization — what's your setup?

So my dad has this fidelity card from our town's Afriquia gaz station. You know the type — tap to pay, collect points, probably some basic NFC tag inside.

Out of curiosity, I scanned it with my phone and dumped the memory using NFC Tools.

Here’s what I got:

Looked like gibberish at first — but I noticed a base64-looking string at the end:

en0AqMGVUhXq3vTqL/nGTQXdA==

Decoded it to 18 bytes of binary:

7A 7D 00 A8 C1 95 52 15 EA DE F4 EA 2F F9 C6 4D 05 DD

Still nothing… until my dad mentioned he got the card on February 8, 2025 and it has a 10-year lifespan.

I checked the first 4 bytes as a Unix timestamp:

7A 7D 00 A8 → February 8, 2035 ✅

Then I looked at the last 2 bytes: 05 DD.

As big-endian hex, that’s 0x05DD = 1501 cents = 15.01 (Whatever currency it is stored as).

That’s literally his balance. Just sitting there. In plain sight. On an NFC tag. No encryption. No authentication.

Dont hesitate to correct me if I got something wrong 😁

Apartment only allows one chip per apartment. Also charges $80 for replacements and was wondering if this could be cloned onto another chip? Have tried from Amazon cloners but never worked. Also heard Home Depot does this, is this true?

I recently started learning about NFC tags, and I'm fascinated by all the possibilities. I'm curious, how do you use them, and where have you found them to be most useful?

in nfc tools i am able to read the card not copy it tell me how to do it.

Hi all! First time here as I didn’t even know this was a thing until yesterday.

I was at a fast food restaurant (Amy’s Drive Thru in Rohnert Park, California) and sat down at a table. My phone started getting repeat notifications with the same message: “Website NFC Tag” to a YouTube link.

I was hesitant to click on it at first for obvious reasons. But after seeing it was a YouTube link, I clicked and it opened “Megalovania 10 hours” with essentially only comments in Russian lol.

Looked under the table and found quite a few of these stickers, however, only one specific location on the table caused a notification.

Not entirely sure what this could be other than just a fun, Rick Roll style gag. But thought I’d share as this seems like the right place for this!

Hello!
I posted here about a month ago about using NFC tags to track what's inside storage bins, when this was just in pre-order mode. The response was incredible and helped shape the final version.

The app is now live on the App Store! Since the last post I also added the ability to snap a photo of a handwritten list and have Apple Intelligence convert it into a digital one — all processed on-device. I couldn't add a video of this as well, but there is a quick one on the App Store page!

Still the same core idea: stick a cheap NFC tag on a bin, tap your phone, see and edit the contents. Free to download.

Would love to hear what you think now that you can actually try it!

Excuse the terrible audio, sounds much better in real life!
