CoreNFC reads Chinese national ID card
Our function is to use CoreNFC to detect various NFC chips to obtain the unique ID in the chip. Under the iOS14.5 system, it is normal to read other cards. When reading the ID card of a Chinese mainland citizen, the unique ID obtained is empty and all 0. The details are shown in the following figure: Since NFC reads the ID card of mainland Chinese citizens can only be used after iOS 14.5, I don't know if Apple did not open it, or what restrictions Apple has, it has been tangled for a long time. With the same code, it is normal to read other NFC cards, as shown in the figure below: Hope someone can help me

Reply to Unlocking Level Lock with apple Watch or Phone
I also bought the Touch earlier this year (February, so ~10 months ago), and was also hopeful that holding up phone to unlock would eventually be a firmware/software update enabled feature. From my internet searching, there's no indication Level intends to do this with the Touch. Instead they are pushing the Level +, which is basically the same as the Touch except with Apple HomeKey. Some folks online claim the + has a stronger radio than the Touch. I have been very disappointed with the unreliable performance of the touch to unlock feature in the Touch. It only works for me if I pull out my phone and open the Level app, and watch as the text indicator in the app goes from touch to unlock not ready to touch to unlock ready. After that I can touch the lock and it will indeed unlock, but of course having to pull out your phone completely eliminates the the value of touch to unlock. Some reddit folks have said they use NFC stickers and homekit automations to enable NFC to unlock behavior with t

App Clip Banner in lower version of iOS devices
Hi, Currently, I am maintaining an App Clip. Due to the application size limit and the features that we have to put into the App Clip, we had decided to go with iOS 16 + which allows maximum size limitation of 15 MB. But the problem is for devices with lower version, when they are scanning NFC tag or QR code, instead of seeing the website to popup, they are seeing the App Clip Banner with notification to update the iOS version. Is there anyway for in lower versions of iOS, let the users seeing the website, not the App Clip popup?

ERROR: NDEF Tag does not contain any NDEF message ~ Flutter
Hello, I tried to build an NFC App and it works still fine - beside one big problem. When I want to describe a newly purchased NFC tag with my app, this does not work with the error code: ERROR: NDEF tag does not contain any NDEF message. However, if I open another NFC app from the AppStore, it works perfectly with the tag. It is also strange that once I have written a text to the tag with another NFC App, my app now works perfectly and I can now write to the tag. So my question is, why can I only write NFC tags with my app that already contain a message? I would also be interested to know how I could programme my app so that it can also write to empty tags. Since this also works with the other app from the AppStore, it must be possible with iOS. Many thanks in advance to all those who take the time to deal with my question.

Has there been any major change at NFC transceiver since iPhone 12?
We've developed an app which performs data transfer with a control board over NFC. The NFC tag we're using is a type 2 NXP Ntag with 2k memory. The app works fine with models up to iPhone 11. However with iPhone 12 onwards, we've been experiencing constant NFC tag detection or NFC session termination failures. Moreover, when it fails one time, it keeps on failing for next consecutive attempts no matter how I hold the phone next to the NFC chip. I've tried all distances from 0cm to 4cm and all directions, nothing works. I'm confident that nothing's wrong in the NFC implementation since the same app works absolutely fine on other iPhone models with iOS versions ranging from 14.6 to 15. Is it something related to sensitivity of NFC transceiver? Is there any way it can be compensated at the source code?

Reply to NFC Tags won't read after iOS 15.4 update
Hi All, if it helps anyone, I have somewhat the same issue. When scanning NFC tags in automation app or NFC tools, it never fails. If I try then to read the NFC tag with the my phone, it doesn’t work. One solution I found is to lock the phone, and with the screen off, position the iPhone over the nfc tag, and press the side “wake” button. It reads 100% of the time for me. hope it helps.

Reply to NFC Tags won't read after iOS 15.4 update
I found that if I turn off cellular, then I can read NFC devices. Not worth it for a silly device, but probably worth it for your GCM.

Is there any guidance how to customize scan dialog (Ready to Scan) which is launched by NFCTagReaderSession? E.g. size, color, icon or is it limited by operating system?

Reply to Using Wallet.app to open doors with NFC reader
Tried the Wallet Creator as given above. But unfortunaly it will not work. It can provide a serialnr. But it will not scan the NFC inside the lock or card. So we have to look further. Anyone a solution? Question: How to unlock the Ikea Rothult by using the iPhone NFC.
