“nfc”

We have an application that reads temperature from a device using NFC. We would like to continuously update this temperature on-screen while the user holds their phone in front of the device but this is not possible as the scanning sheet is blocking the view! Is there any way to disable this? I am not looking for background scanning as this relies on NDEF whereas this is a command driven application. I am developing using Xamarin for iOS 13 and above with NFC writing capabilites.

I tried to upload Application after updating my Xcode and then I started to get this error . ERROR ITMS-90778: Invalid entitlement for core nfc framework. The sdk version '14.2' and min OS version '14.0' are not compatible for the entitlement 'com.apple.developer.nfc.readersession.formats' because 'NDEF is disallowed'. In my info.plist I haven't added any com.apple.developer.nfc.readersession.formats Tried by adding it still same issue . Need to know why and what was the issue

I cannot read my ID card on iPhone

So i am tring to use the new CoreNFC features to access my access card ( iso14443 tag type iso7816) I can able to read the card while trying to write getting below error. (Error Domain=NFCError Code=401 Stack Error UserInfo={NSLocalizedDescription=Stack Error, NSUnderlyingError=0x282322a90 {Error Domain=nfcd Code=21 Connection Closed UserInfo={NSLocalizedDescription=Connection Closed}}})

Has anyone else had this issue? I made some Personal Automation shortcuts with NFC tags. Once I went to test them it would not read the tag. I tried on my friends device by setting up the whole thing and it worked fine. I am using an iPhone XR. Any ideas?

I can use it online but on stores can’t work

Over the past few weeks, we have noticed a big difference in how well our App Clip App reads NFC tags compared to our Full App. The full app, which has the scan NFC button like all full apps, reads the NFC chips perfectly 100% of the time. The App Clip version of the same app has slowly started to be consistent in reading the NFC tags. Has something affected the App Clip NFC reading in the past few weeks after the iOS Updates? Can you tell us what we can do to make the NFC reading of the App Clip App as responsive as the NFC reading of the Full version of our App? Please advise because we want to make App Clip via NFC great, but not getting a consistent NFC read compared to the full NFC app is definitely a problem for consumers adoption.

Hey. I want to configure URL opening with nfc tags. But when I program tag, it doesn't work well in background reading mode. Or it doesn't work at all. Each iPhone is different. tag - iso 14443a NTAG 312 Am I using the wrong tags? Or do you need some other way to write the tag? What prevents you from reading the first time?

Recently Apple updated Xcode and had one change for App Clips. For a URL to launch it needs the additional of nullable See link here. - https://developer.apple.com/documentation/app_clips/apactivationpayload/3580308-url?changes=latest_major&language=objc One problem. My App Clip works fine but there is nowhere in the code where to use the code defined in the link, either the previous or the new updated code. I only use NFC for the App Clip. So does this not involve NFC? It mentions payload which I'm used to hearing about with NFC chips, so that's why I'm wondering about it. I've also noticed NFC reading less consistently as background reader. Please let me know if this line has anything to do with NFC, and why my app would still work even though I don't even use this line anywhere in my code. Thank you truly and any help is appreciated. I just don't want to be missing something that might break my app in an upcoming update.
