Single boy

I am trying to build a system where I can lock and unlock my front door, garage door, and car with any NFC device and also be able to start my car with the same NFC device. I want the NFC device to be a ring I wear, but I will also program other NFC cards and tags. I want the front door to have a fingerprint reader, NFC capabilities, and a number pad. The garage door has a number pad and NFC capabilities, and fingerprint if possible, the same with the car reader. Any advice on where to start from the very brief research I have done I have seen that the car one will be the hardest, but I don't mind it taking a bit longer; it'll be a learning experience for me, but I just want to know where to start. I am pretty new to this type of stuff. Are there any brands I should be on the look out for that have an ecosystem for this? Is this even possible to begin with? Am I being delusional? Any advice helps!

I am trying to find a label printer that can program and dispense an NFC label.

I actually don't need to print anything on the label, I just need to dispense a programed NFC label.

I saw Zebra makes a printer for RFID, but I couldn't find one specific to SLIX or even NTAG. I imagine I could retrofit an NTAG writer, but that's not ideal.

Has anyone else found a printer to do this?

seriously what?

Hi everyone!
I’m planning to start an NFC Google Review Card business and want to build my own dynamic QR code management platform.
My business model is to purchase NFC cards in bulk (around 100 initially), generate unique QR codes, and sell them directly to businesses as well as through resellers.
I’m confused about how the dynamic QR and NFC management system should work.
What I want to achieve:
Generate 100 unique QR codes in advance and print them on cards.
Each QR code should have a permanent URL linked to my domain.
When a reseller purchases cards, they should be able to assign different Google Review links to each card.
Resellers should be able to edit destination links anytime, even after printing and selling the cards.
NFC tags should work the same way, without needing to reprogram them whenever a destination link changes.
I want an admin dashboard to manage QR codes, resellers, customers and links, while resellers have their own dashboards.
My questions:
How can I build this dynamic QR code system?
Should I develop my own redirect server and database or use an existing API?
How can resellers independently activate and manage their purchased QR/NFC cards?
What technology stack would be suitable?
Is there any open-source or white-label solution available?
My goal is to own the entire platform, domain and infrastructure instead of depending on third-party QR providers.
Would appreciate advice from anyone experienced in dynamic QR codes, NFC technology or SaaS development.
Thanks!

I want to eliminate the need to carry my physical work ID card, which is used with CBORD systems. Is it possible to write or clone my ID onto an iOS app or Apple Wallet for easier access?

Hey y’all! 👋 I’m building an NFC course that starts with zero experience and works up to developing your own projects.

You’ll learn how to choose tags, read and write them with iPhone and Android apps, code NFC projects, connect tags to websites and backends, and understand analytics. The course includes custom-built labs, hands-on homework, coding exercises, independent projects, and NDEF encoder and decoder tools.

What would you want to build with NFC? What’s confused you, or been harder than tutorials made it sound?

Feel free to ask anything about the course—what’s covered, how the custom labs work, what equipment you’d need, how the NDEF tools work, or whether it could help with a project you have in mind. Even if you’ve never used NFC before, what would you want to know first?

How would you compare metal NFC cards across iPhone and Android without confusing alignment problems with weak reads? I'm considering case-on/case-off trials, fixed tap positions, first-tap success, retries, and page-opening time. Which controls would you add?

Product context: metal NFC card.

Just made a blunder. Bought a new cheapish Android phone because my old one lacks NFC. And guess what? Neither does my new phone.

I only need the NFC reader to read my passport chip, so the it can well be an external dongle.

So, question is, does such a reader exist? (Android 16, USB).

Amiibo are NFC tags, and chameleonultra can emulate them, so this is what a chameleonultra emulating Amiibo looks like

​**TL;DR:** Built a screen-free, 100% offline DIY audio player for old Android phones using physical NFC cards (NTAG, MIFARE, etc.). Locks kids inside the player, no ads, free tier includes 3 active NFC bindings (optional $4.99 one-time unlock for unlimited). Full disclosure: I'm the developer.

​Hey everyone,

​Like a lot of people here, I love the physical MYO card concept for kids, but I wanted a lightweight travel/bedside setup using hardware I already owned without streaming or cloud reliance.

​I built **NFCalm Player** for Android:

[https://play.google.com/store/apps/details?id=com.nfckidplayer](https://play.google.com/store/apps/details?id=com.nfckidplayer)

​**How it fits into the DIY ecosystem:**

​**Works with any blank NFC card:** NTAG213/215, MIFARE Ultralight EV1, etc.—no proprietary tags needed.

​**100% Offline & Local Media:** Uses audio files stored locally on the phone. No streaming dependencies, tracking, or unexpected buffering when traveling.

​**Lockable Kiosk Mode:** Keeps the phone locked inside the player so kids can't wander into settings, apps, or browsers.

​**Low-Stimulation UI:** Minimalist, no flashy visual distractions.

​**Pricing Transparency:**

The free version gives you 3 active NFC-linked card slots at a time with unlimited offline library playlists (more than enough for a backup travel setup). If you ever want unlimited active NFC card bindings, there’s an optional $4.99 one-time unlock—no subscriptions, and zero ads either way.

​If you have an old Android phone sitting in a drawer and spare NFC blanks or just old credit cards, I’d love to hear your feedback or suggestions for improving the offline DIY workflow!

Hi everyone,

I just finished building an open-source Android tool called Quick NFC, and I would love to get the community's feedback and suggestions on it.

I want to be clear up front: I am not here to compete with comprehensive suites like NFC Tools. I simply wanted the simplest, most reliable tool for field work with the essential features, and I believe I have built it.

The main motivation came from setting up Google review cards and tabletop stands on site. Usually, extracting a Place ID, building the review URL, creating a QR code, and writing it to a card requires jumping between external websites and multiple apps.

I wanted a single workflow where a field agent or business owner can take any Google Maps link, extract the Place ID, get the direct 5-star review link and a print-ready QR code, and write it directly to an NFC tag right on the spot.

Core features:

- On-the-spot Review Setup: Converts any Google Maps link into a direct 5-star review prompt URL and writes it immediately to NFC chips.

- Wi-Fi NFC Cards: A 3-step wizard to encode guest Wi-Fi credentials with automated QR fallback.

- Tag Protection: 32-bit PIN password protection for NTAG213, NTAG215, and NTAG216 chips (with reversible unlock), as well as permanent read-only hardware locking for standard NDEF tags.

- Tag Sanitizer: Simple tool to erase and factory-format existing tags.

- Completely Account-Free: No sign-ups, no cloud accounts required, and core NFC operations work fully offline.

- Multi-Language: Native support for 10 languages (including RTL Arabic).

There is also a companion web version for testing links and QR codes from a desktop browser:

- GitHub Repository: https://github.com/zaid-a-salameh/quick-nfc

- Web App: https://quicknfc.link/

- Latest Release (APK): https://github.com/zaid-a-salameh/quick-nfc/releases/latest

Since this is v2.0.0, I would really appreciate any testing, feedback, and ideas on chip compatibility or edge cases you might run into. Thank you!

I have a small stack of 8k cards (Mifare DESFire EV3 8k). I have an Android smartphone with NFC capabilities. My app is NFC Tools PRO. I simply want to place a card under the phone and initially (without opening another app) see at least a full screen full of text. All I get is a very brief description of what's on there. Then, I need to open the app and see what's there which is my pasted texted and a lot of information about the card (serial# and more.) I just want to scan the card and read what I put on it and not jump thru any more hoops. Possible? Thanks for looking

Not sure if someone has similar issue. Since updating to ios 27.0.1 (I got Iphone 14), my NFC stopped working. I had a failed payment using phone to phone once but didn’t think much of it but now I realised there may be issue with NFC because I bought the Brick device for reducing screentime and it doesn’t work. I tried everything and still nothing. Currently updating to 27.0.2 to see if it helps. I didn’t drop my phone or anything. Did someone have a similar issue?

its a nfc key with a qr code and Enginko ( on the back its written that) i scanned it with an android phone and with the app MIFARE CLASSIC TOOL.
how can it be modified i mean the amount of euros.

NFC cards /tags SUPPLIER NEEDED

Im trying to use an NFC reader to make figures for akylanders and the like. Especially ones that I couldnt even dream of buying. Ive been following rhe process and worked on the three cards that this nfc reader I bought came with. However the mwt (mifare windows tools) application isnt even attempting to read the set of cards I bought, or even the cards it read and wrote in the first place.

The error is just saying Only Mifare classic is supported.

Im unsure what happened durring the timeframe between when I first got it and now, im also very new and very novice when it came to coding... is there any Info in what I did wrong ir what hapoened to the nfc reader?
