NFC TAG IPHONE
I have a client who asked me to create an app that reads nfc data, but this data needs to come from a built in iPhone nfc tag, so the app will read through nfc the SECOND device info. my question is, does the iPhone has a built in nfc tag? if so, can it share any device info?

Bad user experience because of NFC timeouts
We are developing an app for the online identification function of the German National ID Card. https://github.com/Governikus/AusweisApp https://apps.apple.com/de/app/ausweisapp-bund/id948660805 Currently there are two NFC timeouts we are not able to influence because there is no API. A NFC Session has a maximum lifetime of 60 seconds, independent from any card communication. When a card was detected the connection will only last for 20 seconds. Combined there is also something like a worst case: The user presents the card 55 seconds after the session was started: The connection will only last for the remaining 5 seconds of the session. The identifications works as follow: The user clicks on a link on a website and our app will appear. After selecting access rights the NFC session is started. Sometimes the user start to search for their ID card now and this takes some time. When the 60 seconds are over we start a new session until there is a card or the user aborts. After establishi

Reply to App Clip not opening from QR Code/Appclip codes
Confirm that you are following the instructions from Choosing the right functionality for your App Clip: To ensure a fast launch experience, App Clips must be small: If you make your App Clip available on devices running iOS 15 and earlier, the uncompressed App Clip binary can be up to 10 MB in size. If you make your App Clip available on devices running iOS 16 and later, the uncompressed App Clip binary can be up to 15 MB in size. If you make your App Clip available on devices running iOS 17 and later, the uncompressed App Clip binary can be up to 50 MB in size if it meets the following conditions: The App Clip only supports digital invocations — for example, from your website or Spotlight search — and not from physical invocations like App Clip Codes, QR codes, or NFC tags People use your App Clip in situations where a reliable internet connection is likely, for example, at home Your App Clip doesn’t support iOS versions prior to iOS 17 Aim to keep your App Clip well below the applicable limit.

Reply to launch app by scan NFC Tags
You can either implement background NFC reading to read the data from the tags to determine what video will play, and then send a notification to the user to open the app. Or you can embed a direct URL to your app and have the system put up a notification to launch your app. You cannot launch your app in the foreground to play a video without the step where the user taps on a notification of some kind.

Reply to NFC launch app
If you implement an App Clip, then the NFC will launch your App Clip or your App (if the user installs it). But it will still need the user to tap the open button on a notification to actually launch your App or App Clip. You cannot have your app launched into the foreground with zero user interaction.

Unable to send Mifare commandos on iOS
I have created a Flutter application to scan Mifare DESFire cards on Android and iOS. I have tried using both flutter_nfc_kit and nfc_manager which both use CoreNFC. On both platforms, I can get the basic information on the card. However, only on Android, I can read data from the card by using Mifare commands. On iOS I am getting a 0B response. I have the following configuration inside my Runner.entitlements: com.apple.developer.nfc.readersession.formats TAG I have added the following keys inside my Info.plist file: NFCReaderUsageDescription Access NFC com.apple.developer.nfc.readersession.iso7816.select-identifiers D2760000850100 ... However, I have noticed that I will get a different response if I add the D2760000850100 key in the Info.plist file. When I have this key added I get an error when executing a Mifare command: PlatformException(500, Communication error, Tag response error, null) So for that reason, I decided to remove the key altogether. Now everytime, I execute a Mifare comm

Reply to App rejected because of NFC used in third party
We can't help you with what happens in the build with that podspec. Anything we say will be assumptions. As for app rejections, unfortunately, this is all hypothetical. App Review will handle each app on a case by case basis and it is not possible for anyone to say there will be an issue without knowing how the app is built, what NFC APIs are being referenced or not, and what the app is for. And also, what the rejection is for exactly. If they get a rejection, the app developers can ask for a technical review and determine what exactly is causing the rejection and how they can fix the problem.
