“nfc”

as I see , the post is old ,and I could not find any new information. Does it actual now or not ? I have same issue, my app should open door(NFC), when I put phone near NFC tag apple wallet app triggered.

How did you emulate an NFC Tag with an android device that was readable by an iPhone? I've tried several android NFC apps that did not emulate on an iPhone natively unless you used the same compatible app on both phones.

Incredible. The bug is still there in the official iOS 15.5 release! I used NFC tags as HomeKit shortcuts, none of them work anymore :( I advise everyone here to fill a bug report with Apple's Feedback Assistant: https://feedbackassistant.apple.com/ (iOS → CoreNFC API) If only one or two people fill a bug report, nothing will change before many iOS releases. We need to work as a team here and act in group in order for Apple to react quickly. And if you're a registered developper, please fill a bug report using Apple's Radar system too.

The same for me. iPhone SE 2020 after upgrade 15.4.1 NFC down. ITS VERY IMPORTANT FOR MY HEALT, IM DIABETIC. please fix this IMPORTANT bug!!

Similar situation here. New iPhone 13 Pro running iOS 15.4.1. I have a CUPLTag temperature and humidity logger that uses NFC to download the sample data. Before 15.4 update it worked every time. Afterwards, it rarely works at all. In fact, I only think I've gotten it to work this way twice since the update. Yet I can launch the NFC Tools, tap Read, then move it near the tag and it reads immediately, every time.

If you have changed your LCD screen and it is not able to update because of this warning checking for a software update failed because you are not connected to the internet ios . You can try all you want but the only chance is to remove the NFC FROM THE ORIGINAL SCREEN and put it on the screen that was replaced. After that, just install it without any problem.

I was on a thread about this issue that seems to have since disappeared. Immediately after updating to 15.4.1 I was no longer able to use my phone to read a continuous glucose meter and apple pay no longer worked. This was IMMEDIATELY after the update. I use my phone to read a medical device, as do millions of other people worldwide. Apple is pushing this technology for medical devices. I've done three factory resets - two at the store. When tested my NFC system says that it works. However, it no longer reads my device or Apple Pay at the cash register. From a variety of forums, I can see that this is an issue that is now frequently occurring when people update their operating system. My phone is less than two years old. I was offered no solution at the apple store other than purchase a new phone. It is quite frankly grossly unfair to suggest that I need to purchase a new phone due to a known issue. Apple is jeopardizing the health of millions of people who use wearable medical devices. Those who use

The same thing happened to me when I updated to 15.4.1. I am so frustrated. I have an iPhone SE 2020 and it's not even two years old yet. I use my phone to scan a continuous glucose sensor. It worked absolutely fine all day until I did the update. Immediately after I did the update NFC no longer worked. I did trouble shooting over the phone. Then went into a store. At the store the rep assured me that my phone was absolutely great and nothing was wrong with it -- despite the fact that it no longer read my CGM. In the process I tried two different expensive sensors to isolate if the issue was the sensor or the phone. Two sensors didn't work. I then used my son's phone to scan the sensor and it did work. Mind you, these sensors are $70 each and due to this issue I had to waste two of them. Since then I've had to carry two phones with me, mine and my son's old crusty iPhone 7 just so I can monitor my medical device. After I went to the Apple store and was told my phone was fine, I went to the grocery st

i'm trying to call from my View Controller a NFC Reader in a different ViewController. What do you do exactly ? Are you sure the second controller is already loaded when you call ? If both ViewControllers are loaded did you try to push notification or use delegation ?

As this post is two years old, has there been any change to Apple not supporting NFC Tag emulation mode in the meantime?

I have the same problem. iPhone 13 mini. NFC is completely dead. Apple Pay on web is working fine. On physical terminals the phone does not recognise card reader nor is able to recognise any NFC tag. What is worse - we have tried another 3 iPhones with the same IOS version and everything is fine so not sure what is the pattern here. I was communicating this to apple support and they run diagnostic - no problem found. No workaround like resets are working.
