“nfc”

Hey everyone! So I've been creating a program to extract the UID (unique identifier) from an NFC Tag and have been stuck on this very last problem: On the third line I created a variable which I want to be able to change called tagUID, initially just UID. If you look down to the very last line of code, you see that (if there is a connection to the tag) the last thing it's supposed to do is change the state of tagUID to whatever the UID of the tag is, but it's refusing to do so. Everything else works great its only not changing that variable! class NFCReader: NSObject, ObservableObject, NFCTagReaderSessionDelegate { @State var tagUID = UID var session: NFCTagReaderSession? func activate() { self.session = NFCTagReaderSession(pollingOption: .iso14443, delegate: self) self.session?.alertMessage = Hold Your Phone Near the NFC Tag self.session?.begin() } func tagReaderSessionDidBecomeActive(_ session: NFCTagReaderSession) { print(Session Begun!) } func tagReaderSession(_ session: NFCTagReaderSess

Will have iphone nfc support for card emulation

Hello, Currently I use typical ID cards to unlock doors in my institution using NFC. I am trying to manipulate the Pass.json file to allow for NFC Door Unlocking. Here is what I think I will be using: {nfc:{message:EXAMPLE,encryptionPublicKey:EXAMPLE}} What I am trying to do is extract the NFC data from my ID card and use it for the NFC message in my Pass.json. If there is any help on how to extract this it would be greatly appreciated. Thanks

I read a typeB card by NFC API.I'll run this method when there's a card reading error: [self.session restartPolling] ; but after that,the delegate tagReaderSession:didDetectTags: will not be called sometimes in iOS14. This is a low probability event that can be reproduced in about 10 or 20 retries. Has anyone had this problem? Is there anyone who can help me solve this problem? Thanks, guys.

when i use shortcuts -> automatization-> creat automatization -> NFC. My iphone can see my tag. But when I create my own project with coreNFC to detect nfc tag, my iphone cant see my tag, but it see other tag. Tag mifare import UIKit import CoreNFC class ViewController: UIViewController, NFCTagReaderSessionDelegate { @IBOutlet weak var UIDLabel: UILabel! var session: NFCTagReaderSession? override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. } @IBAction func CaptureBtn(_ sender: Any) { self.session = NFCTagReaderSession(pollingOption: .iso14443, delegate: self) self.session?.alertMessage = Hold Your Phone Near the NFC Tag self.session?.begin() } func tagReaderSessionDidBecomeActive(_ session: NFCTagReaderSession) { print(Session Begun!) } func tagReaderSession(_ session: NFCTagReaderSession, didInvalidateWithError error: Error) { print(Error with Launching Session) } func tagReaderSession(_ session: NFCTagReaderSession, didDetec

Hello! I created my own pass with nfc and want to test it on my iphone, how can i do that?

So I want to create a Apple Wallet Pass that can send a string message with the NFC chip when I arrive at my workplace, but my question is: Can I create a pass that send the same generic string when sending from the NFC chip? So we have a security system at work that uses these nfc chips that have hardcoded some values in them and I want to know if I store this value in the NFC chip on my iPhone, that it can send the same value to the NFC reader? or do I have to have the terminal for reading the encoded values?

Hello everybody! Thx for any info. I have NFC key. When i go to shortcuts on my iphone xr and make scan nfc, my iphone find my nfc key tag, so i think iphone can read this tag. But when i download app from appstore, I tried 10 - 12 different apps. This apps cant see my nfs tag. Why?

Does someone know how to avoid iPhone 12 and 13 NFC not detecting tag bug once scanning for very first time and also after scanning twice?
