I recently got a Toughbook CF-33 and it has a built-in contactless smart card reader. From what i have read on the toughbook subs and forums, the windows 11 native drivers work just fine - which are installed (checked for updates, too) - Microsoft Usbccid Smartcard Reader (WUDF) driver.

The hardware is apparently:

• Model Number: CF-WSC332 (or CFWNF332)
• Type: 13.56MHz Contactless Smart Card / RFID Reader (supporting ISO 14443 A/B and ISO 18092 standards)

When i open up NFC Tools in the Information tab I get the message Waiting for an NFC tag. When I hold a bank card or my work ID up to the reader, windows plays the same chime when a USB device is plugged in a recognized...but the software does nothing. When I move the card away from the reader, it is the same chime as when you un-plug a USB device.

What shall i do, and are there any easily found more basic chips that i can use other than the two aforementioned ones? I was wondering if I could get an app on my android phone for like NFC a contact card or something non encrypted to see if that is my issue.

What are your thoughts?

Hello, i have a trasnit card uses MIFARE DESFire EV3, can i emulate it? Or do something to it to come and go free through the trasports (metro station that you tap the card on the screen to open the doors)
The other things is the Arcade Games that its the same concept with the transit one but i dont know what secure chip they are using but is it possible on this one too?
I'm new to this and i would love someone to give me more info in this one.
Thanks!

Hi, I have two distinct Mifare Classic badges to enter my building, and was wondering if I could write both to a single tag.

Would writing sectors 1 through 4 of badge A in their initial positions, and sectors 1 through 4 of badge B on sectors 5 to 8 on badge C work?

Lots of smart watch can do payment but I would like to use it for development purposes. So far I only found the T-watch Ultra from LilyGo which is out of stock unfortunately.

Do you know any other watch that can do that ? (Or any wearable)

Hello everyone, i want to host my contact details to share in a event but i am struggling with adding it to nfc tag.

As you all know generally iphone asks to download file first but i don’t want to engage in all unnecessary steps. There are few old reddit posts but they are not relevant now as google drive and drop box is not working for me or i am not able to set it properly.

Help would be appreciated.

My iphone nfc is not working, any idea how to fix it ?

TL;DR: Trouble getting iPhones to read URL in an NFC tag when tapped. Help?

I'm a high school teacher and I've designed and 3D printed hall passes for teachers. Then I added an NFC tag to the back of each tag with a simple URL unique to the teachers classroom. Teachers check a kid out with an app I made. If an admin finds a kid in the hall they can tap the pass and see where they're from, where they're going, and how long they've been out. It's super slick.

Alas, my android phone always detects it and so do other android phones. But apple is very hit or miss. I don't know what I'm doing wrong. I had a student try with their iphone and they detected each tag and was told they were not authorized by the app (as expected). But the principal and several teachers I tested with just can't detect the URL.

I'm using some NTAG215 tags I got off Amazon. I'm using NFC tools app on my phone to write the URL and lock the tag. I can link to the specific tags but didn't want mods to flag me as a bot before I got some help.

I feel like it might be a security thing, but don't know what setting it is on the phones. The link is direct to a script extension on a Google sheet. I can't even send it by email because the district security flags it as potentially malicious.

EDIT: Confirmed. Larger NFC tag did the trick. 2.5cm diameter rounds are read by all iPhones tested.

I am starting a business of nfc card which help the business for rating and business to understand the customer rate review and can analysis this customer in which area the review is good or bad and also we can manage the manu like restaurant in which table customer site more time and also manage the manu manually if they want to add or remove customise it’s manu i will launch my application very soon within hours or day .

I switch from Apple to Google Pixel 11 Pro XL around the end of September, Everything worked fine at the beginning, but for the last two weeks, I've been having trouble with the tap and pay NFC contactless payment method with my phone.

It is so weird because it's not like not functioning at all. Sometimes it goes well, but most of the time when I tap on the machine, there is no reaction at all.

And I have contacted Google support twice so far. I contacted Google support a few days ago for the first time and I've been emailing them for the past few days. They keep asking me to screenshot when it's not working and keep telling me they can see the transaction goes through, so there shouldn't be any problem. Until I sent them the video, when I paid at the restaurant and there was no response when I tapped on the machine ( I even removed the case to try but didn't film it) they said it's my phone case too thick to block the signal from the terminal. Which is funny because the phone case is also from Google, so their own case is blocking their own device's signal?

And I just called Google support again today at night around 2AM. Apparently I have to wait for another week for their response to see what they can do with my phone.🫪🫪🫪🫪🫪🫪🫪🫪

Hello NFC community, you can now fully configure ICODE ICODE 3, SLIX, ICODE DNA and NTAG 5 in NFC.cool iOS. Android is coming soon!

You can read more about it in my latest blog post.

I want to start that business, but I don’t know how to sell them and how to balance that with school. Also can manager of business buy that cards or I should only say that to the owner?

Bonjour je gère un tiers lieu et pour éviter le papier je souhaite donner des cartes RFID qui donne le programme du mois, le lien vers notre site internet…
J’ai vu que c’est possible pour les cartes de visites.
Vous me conseillez quoi comme programmeur et comme type de cartes à l’achat?
Merci

It's probably quite simple but I'm quite new to NFC. I would like to use a tag to remind me of watering my plants. Ideally I would scan a tag after watering and it will set up a Google Calendar task/event for next week. I have NFC Tools Pro and NFC Tasks. The problem seems to be "a week from now" part.

I am part of a charity and we use SumUp to collect ePayments and donations.

This past weekend we set up a number of volunteers with SumUp on their devices so they could collect donations using Tap-to-pay. My S24 set up very easily. I did the slide the card up the back of the phone to find the NFC antenna check.

However when I tried to collect any payments the phone didn't seem to recognise the card very quickly. It took about a minute of slowly moving a credit card around the antenna area. At times the movement had to be so slow it was frustrating. Eventually payment was taken. This is a pretty useless performance when you are trying to maximise donations.

When I use my S24 to pay for stuff it works very quickly.

Any idea why the S24 was so bad at taking payments when other phones worked quickly?

Hey everyone!

A while ago I wanted to use my phone instead of carrying a physical NFC card around, but most existing solutions required rooting the device. So I ended up building my own little Android app called Emula.

It's arguably a bit of AI slop (okay, quite a bit of AI-assisted coding went into it), but it's been tested on actual devices by my colleagues, survived Google's closed testing requirements, and recently got approved for production.

With Android already introducing APIs for this, it feels like things are heading in that direction anyway. Maybe Google or other manufacturers will eventually bring similar functionality to their official wallet apps. Until then, it's been a fun little adventure, and hopefully someone else will find it useful too.

For now, I've decided to keep it in open testing to gather more feedback and expand the device compatibility list.

What it does:

• Emulates 4-byte NFC UIDs without root on compatible Android devices.
• Reads UIDs from physical cards or lets you enter them manually.
• Saves multiple UIDs and lets you switch between them.
• Includes built-in NFC compatibility diagnostics.
• No ads, accounts, analytics, or cloud storage.

Requirements:

• Android 15 or newer. No root required.
• A one-time ADB permission grant is required before UID emulation can work. Installing the app alone does not grant this permission.

Steps to grant the ADB permission:

1. Enable Developer options on your phone, then connect it to a computer either: via a USB cable with USB debugging enabled or via Wireless debugging, pairing and connecting the phone through ADB.
2. Once connected, run this command on your computer: adb shell pm grant dev.dunno.emula android.permission.WRITE_SECURE_SETTINGS
3. Check if button "copy adb command" has disappeared from the app. Otherwise, restart the app completely.

Compatibility also depends on your device’s NFC hardware and firmware, so Android 15+ and the permission grant do not guarantee compatibility with every device or reader.

A few caveats:

It only emulates the UID, not the card's memory, encryption keys, or authentication. So this is NOT a universal MIFARE cloning tool. It is intended for systems that rely on UID-only identification and that you own or are authorized to test.

Google Play: https://play.google.com/store/apps/details?id=dev.dunno.emula

Successfully tested so far on:

• Google Pixel 8 Pro, Pixel 9, Pixel 10
• Samsung Galaxy A16, Galaxy S23 Ultra, Galaxy S25 Ultra
• Sony Xperia 1 VI (XQ-EC72)
• OnePlus 15 (CPH2747)

I'd particularly appreciate compatibility reports (phone model + Android version), bug reports, or any technical feedback (you can dm/email me with that).

If you've tried it on a device that isn't listed as compatible yet, I'd be especially interested in hearing whether it worked (or didn't!).

Thank you for your attention!
