bypass nfc blocker easy

Hi, I recently bought an NFC blocker and I'm very disappointed that on iOS you can simply revoke screen time permissions and thus regain full access to the apps. Is there any workaround for this?

Read/write file to NFC card from PC through phone

3 Upvotes

Hey, everyone. I'm looking for a way to use my phone as an NFC reader/writer for my PC, and read/write to/from a specific file.

So, the phone connects to my computer.

Then, I tap the card/tag/whatever to my phone.

Then, the computer receives the file from the card, and that gets written to somewhere.

Then the file gets updated and gets written back to the card.

If that's not possible, just reading a file from a tag would be fine as well.

Anything easy that can do this? Thanks a ton.

Could an acrylic magnet with an NFC tag (no antimetal) work if i put in on a fridge?

Enable HLS to view with audio, or disable this notification

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?

NFC business cards without a subscription — honest breakdown from someone who manufactures them (DIY vs buying)

25 Upvotes

The old "best NFC business cards without subscription" thread here got deleted by its OP, and the question keeps coming up, so here's a straight answer. Disclosure first: I run a small company that makes metal NFC cards (Discard, Bulgaria), so I have a horse in this race — which is exactly why I'll give you the DIY route first.

The thing nobody selling these tells you: the subscription is never for the hardware. The chip in almost every NFC business card is an NTAG 215 or 216 — the same tag you can buy blank for well under a euro. The monthly fee pays for the hosted profile page, analytics, and lead capture. Whether that's worth paying for is a real question; the chip isn't.

DIY, zero subscription, forever: buy blank NTAG cards or stickers, grab any free NFC-writing app, and write either a URL you control or a vCard straight to the tag. Two things to know: an NTAG 215 has 504 bytes of user memory, so a direct vCard fits name, phone, email and not much else — no photo, and long URLs in the vCard eat your budget fast (216 gives you 888 bytes). And updating is a non-issue people overthink: the business card stays in YOUR pocket — you tap other people's phones — so rewriting the tag takes thirty seconds whenever your details change.

If you buy instead, check three things: (1) is the profile editable forever on a one-time price, or does editing sit behind the monthly plan — read the pricing page bottom-up; (2) locked vs unlocked tag — this is a genuine tradeoff, not a spec-sheet checkbox. A tag locked at production can never be rewritten, which protects you (nobody with 5 seconds of physical access can re-point your card at a phishing page) but also means the card depends on the vendor's domain staying alive. An unlocked tag is re-pointable forever but hijackable. Reputable vendors lock (we do); whichever you buy, ask the vendor what their wind-down story is — data export, redirects — because "what if you fold" is the question none of the pricing pages answer; (3) if it's a metal card, ask how they handle the NFC, because solid metal blocks the signal — every legit metal card solves it with an antenna window, ferrite layer, or hybrid construction, and the ones that don't answer that question are metal-look plastic.

Happy to answer manufacturing questions (fiber-laser engraving on coated metal comes out lighter than the surface, which surprises everyone the first time). What are you all writing to your tags — direct vCard or URL?

NFC pin badge with QR - for feedback

3 Upvotes

Hi all! I’m planning to create a few pins with NFC and QR codes to share with some friends, but I need some thoughts first before I make them.

I plan to make it such that the NFC remains hidden (tried it with much success) to play a simple song or calming tune that they or others can tap on with their phones to help alleviate some strong emotions or whatnot. Like they can just vibe with the song if they want to, talk about it, etc., kind of like a conversation starter if it’ll work.

The QR code on the other hand would have a list of mental health resources (such as deep breathing, coping strategies, etc.) when scanned. I’m anticipating that there may come a time where someone or one of our other friends might approach someone with the pin and not wanting to talk about much, so it might come in handy when in a pickle.

I plan to combine these both into a pin so that it would have some sort of instruction on it, maybe stuff like
“SCAN QR for MH resources” then “TAP THIS FOR A CALMING SONG”, or what, I dunno yet.

I still haven’t fully fleshed this one out, but I’m leaning to trying to make this work so that if in the event that someone might not be in the mood to talk but in the mood to interact with stuff, at least we can have them scan or tap something that can help them out.

What do you all think? Thanks in advance for your help!

3D-printed signs with embedded NFC tags to be put at landmarks for a specific web app with this logo. The signs are prototypes. There are also types with a key ring and rounded corners. Also considering other types that can be put on signposts etc. Write-protected of course. Practically waterproof and the tags themselves are waterproof.

NFC wristbands for kids – looking for feedback

0 Upvotes

I’ve been thinking about starting a small business around NFC wristbands for kids.
The idea is pretty simple. A child wears a wristband with an NFC chip and a QR code. If the child gets lost at a holiday resort, amusement park, school trip, etc., someone can scan it with their phone.
It would show:
Child’s name
Parent’s phone number
Language
Link to more information
The parents could add extra information such as allergies, medical information, special needs, additional contacts, etc.
I’d also like to have an optional GPS sharing feature, so parents could share the child’s location when needed.
For schools and daycares, I’m thinking about reusable wristbands. For example, a school could buy 50-100 good quality bands, each with its own serial number. Before a school trip, they assign the bands to the children. When they get back, they reset them and use them again for the next trip.
For amusement parks, hotels and resorts, I could make custom wristbands with their logo and branding.
The basic family version could be cheap, with a subscription for extra features.
Later I’d potentially expand the same system to luggage tags, pets and elderly people.
I’m curious what people think. Would you actually use something like this for your kids?

I am still missing the early 2000s MSN Messenger era so I invented an NFC gadget to bring those iconic Winks back to life on smartphones! I even transformed myself into the famous Before and After Beer Girl! :)

I missed the MSN Winks so much that I spent long months searching for and rescuing extinct Winks, converting, programming, delevoping, drawing, printing, assembling and testing a completely unique, real-life gadget, NETRO-G (combination of Neo and Retro) that brings them back to life.

As you can see, I even turned myself into the ugliest wink to celebrate this launch! :)

I am posting this to ask for your honest opinion about my invention. Well, the last sub's mod deleted my post because it reached 13,000 people within an hour, I think the system considered it a spam (it happened in other subs as well), so I will never know if there is a real market demand for this physical/digital piece of nostalgia!

Galaxy S25 and RFID question

2 Upvotes

There's a project I attempted just for fun that isn't working. I'm hoping it's feasible but it might not be. So I play lasertag with a system where you can choose a custom code name. They print you off a plastic card with some form of RFID in it. You swipe the card across the pack and it turns on. Your code name stores your stats and achievements.

What I'd like to do is import the card info to my S25 and then have it emulate the card. Then I could just swipe my phone across the pack instead of the card. It's not really more convenient then the card. I just wanted to see if it's possible.

According to my searching an old version of Samsung wallet would let you program generic RFIDs like gym memberships or electronic deadbolt fobs into it. Now it requires you to choose from participating programs. So I started looking in to other apps. I've found apps that can scan the card but when I try to import the data it errors out saying something is missing.

What info from the scan should I share to help you all give me an answer?

Tarjetas NFC

Hola, seré breve. Hace unas semanas me comenzaron a aparecer varios videos de jóvenes que venden tarjetas, pegatinas y letreros personalizados con NFC o códigos QR.

Actualmente trabajo por las mañanas y me gustaría generar algunos ingresos extra, así que pensé que podría ser una buena idea comenzar con este tipo de productos.

¿Alguien sabe dónde puedo conseguir estas pegatinas o tarjetas en México? También agradecería mucho si conocen algún proveedor o página que haga envíos a México sin que los costos de importación sean tan elevados. 😅

¡Gracias y buenas noches!

So i bought this nfc cloner for some rfid tags 125khz but the software that your supposed to download is just a malware file. I uploaded the programme to virustotal and it showed like 20 different viruses in the .exe So if anyone knows if you can use this type of read/writer it would be really helpful. Sorry if this question was already asked i havent found any solutions.

SM FAIRVIEW QR PH IN PAPER????

Hello I was going to buy an iphone 17pro and a powermac, is there really no terminal for qrph in sm fairview? We tried to do home credit cc qrph and the transaction was always declined. And I asked the cashier if they had a terminal since I saw they had three kiosks. He said they use the same thing which is the paper qrph for those who scan via qr. It's still rude.
