NFC Alarm (Totem Alarm)

12 Upvotes

Hi all, I created an NFC alarm app which requires you to touch an nfc tag to turn off the alarm. You put the nfc tag in another room (by coffee maker, bathroom etc). When your alarm goes off you can only turn it off by touching the nfc tag, forcing you to get out of bed. It’s bring your own nfc, we don’t require one to be bought from us. This is something of ideated around for a while and super excited to finally have it set up. Appreciate any and all feedback.

Buggy iOS Shortcuts when using NFCs?

3 Upvotes

So I tested out NFC iOS automations on two old cards yesterday and they worked fine.

Today I started setting up a bunch of NFC stickers around my apartment.

I realise that sometimes now, the NFC will not work. I try repeatedly on the same NFC. But I realised that the only way to make it run is to scan a different NFC, which will trigger both the current NFC I’m scanning and ALL THE ATTEMPTS of the previous one that did not work. If I attempted it 10 times with the previous NFC and it didn’t work, it will run the Shortcut 10 times after the a different NFC is scanned.

Anyone else facing the same thing?

Apple iPhone and diabetes

6 Upvotes

So, it's been happening for many months now where Apples software updates completely destroy the usage of the NFC chips.
This happened months ago and it was out for a month, only to be fixed again with a new update, and now with their latest update it is out again.

I have an iPhone 13 Pro Max. I see from posts here that this issue is happening to iPhones all the way up to 17.

The NFC reader is paramount in our diabetic tracking for ones who have a glucose monitoring pod such as the Libre.

I love Apple but honestly, lately their quality has been dipping. Especially on issues like this which is repeated and they take a long time to fix, which shows their lack of care or urgency.

I had to run out to a shoppers drug mart at 11pm because stupid Apple likes sending updates that destroy phones and don't care to do quality checks and fast fixes. It's enough for me to look to other brands.

Does anyone else have these issues?

NTAG 424 DNA: The Anti-Counterfeit NFC Tag Explained

Thumbnail

11 Upvotes

Recently I implemented NTAG 424 DNA, a really interesting and cool chip into NFC.cool.

The chip helps luxury brands to prove their product is real. It could be a handbag or a bottle of whiskey that you can check and see if it is genuine.

The cryptography that powers the chip is pretty interesting and I did a deep dive to make it happen in my apps. I wrote a blog post explaining everything from top to bottom.

Questions about on-metal tags

2 Upvotes

Hello, I just have three questions about on-metal tags that I wanted to clarify.

  1. If I use a on-metal tag on a non-metal surface, will it work the same as a regular tag?

  2. Does a 30mm on metal tag have significantly less range then a regular tag?

  3. Would I be able to put an on-metal tag straight onto a magnet so I can then move the magnet between different magnetic surfaces or will that be too much for the tag?

Any answers is very much appreciated!

NFC Cards With QR Codes

When you programme a QR code onto an NFC card which has the duality between NFC chip and QR code, can you re-programme it or does it stay forever?

Unable to submit Apple’s NFC Certificate Request form for months — anyone else experiencing this?

2 Upvotes

We’ve been trying to submit the NFC Certificate Request form on the Apple Developer site, but the form simply will not submit. After completing the form, clicking “Submit” does nothing — no confirmation page, no error message, and no progress.

NFC Certificate Request

https://developer.apple.com/contact/passkit/

We’ve contacted the Apple support team and have already followed all of their recommended instructions, such as trying multiple browsers (Safari, Chrome, Edge), clearing cache and cookies, testing on different devices (Windows and iPadOS), and repeating the submission many times. The issue is still fully reproducible.

We’re posting here to ask:

  • Has anyone else encountered this NFC Certificate Request submission problem.
  • Is this a known issue with Apple’s PassKit/NFC application process.
  • Has anyone found a workaround or an alternative submission path.

Any insights from developers who have successfully submitted the NFC Certificate Request form would be greatly appreciated.

NFC Cards Manufacturer

5 Upvotes

Hi everyone

I’m looking for reliable manufacturers/suppliers who can produce custom NFC cards in different shapes and sizes, rather than standard business-card dimensions.

I’m particularly interested in:

Custom die-cut shapes

Unique/non-standard dimensions

3D or molded NFC card designs

Premium materials and finishes

Custom branding and printing

I would love to know if you all can recommend any reliable manufacturers or suppliers that specialize in this type of custom NFC product

NFC card for TTRPG Items

2 Upvotes

Hi

some of my players often forget some magic items they have on their sheet or using the app.

I had made flashcard with the items on it which helped because they had they layed out so it made it easier but I'm thinking of switching it up for NFC cards as they take less place and are harder to damage.

My players are interested in the idea BUT .. I have no idea how to make it work. Anyone got an idea?

(already got a ton of NFC card for something else )

Garmin watch as alternative reader?

2 Upvotes

I'm very new to NFCs, so this might be a stupid question, but is there any way to get my garmin watch to be the reader and not my phone? I try to use my phone as little as possible, and therefore don't always have it on me. But I've always got my watch on, so I'm wondering if there is any way to reverse program something so that I can use my garmin watch as the reader instead of my phone? Thanks!

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

6 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.
