nfc

I am reading an NFC tag that contains Basic Access Controlhttps://en.wikipedia.org/wiki/Basic_access_control My goal is to replicate the following Android app on iOShttps://play.google.com/store/apps/details?id=at.mroland.android.apps.nfctaginfo&hl=en

How can I observe notifications triggered by scanning NFC in backgroundMode, I want to customize notifications, add Gif or Image to notification content. because the merchants want to display their images when shopper take their iPhone near goods.

I'm developing an app that between other things reads NFC tags using CoreNFC. I'm checking if NFC is available by using `NFCNDEFReaderSession.readingAvailable`. On iOS 11 it would return false allowing the app to run on devices that don't support NFC.On iOS all the betas up to date the app crashes while loading the dyld with an error saying that the image for CoreNFC framwork was not found.Is this a bug? Is there a new way of checking for NFC?It works on the simulator. Crash only happens on divices not supporting NFC

Hello, Im trying to read data from an ISO15693 tag (M24LR64E-R from STMicroelectronics). Im using react native and react-native-nfc-manager - https://github.com/whitedogg13/react-native-nfc-manager/. Here my code when I send customCommand: tt// init manager t NfcManager.start() tt// waiting for a tag ttlet resp = await NfcManager.requestTechnology(tech, {t ttttalertMessage: 'Ready to scan tag't tt}); ttlet tag = awaitNfcManager.getTag(); const handler = NfcManager.getIso15693HandlerIOS() const flags = Nfc15693RequestFlagIOS.HighDataRate const customCommandCode = 0xb3 tt// some bytes const customRequestParameters = bytes.slice(2, bytes.length) tt// error with this cmd resp = await handler.customCommand({ flags, customCommandCode, customRequestParameters }) But I receive this error (throw exception): [CoreNFC] 00000002 83601300 -[NFCTagReaderSession transceive:tagUpdate:error:]:710 Error Domain=NFCError Code=100 Tag connection lost UserInfo={NSLocalizedDescription=Tag connection lost} Do you k

In my full application I have a universal link configured on an NFC tag that allows me to launch my application via NFC background tag reading and process additional NDEF records held on the tag via the NFCNDEFMessage provided to onContinueUserActivity(). I can use this same NFC tag to launch my App Clip via the same URL when the full app is not installed. However, unlike the full app the App Clip only receives a single NDEF record with .typeNameFormat = .empty. Is this a limitation of App Clip invocations? I have also implemented full NFC reader functionality within the App Clip which does retrieve all the records from the tag, but of course requires the user to tap the same tag twice to read its full contents. Ideally I would like to avoid requiring users to tap the tag twice to read.

I want an iOS application like apple pay/google pay where I can store my physical credit/debit cards. Upon taping on NFC enabled POS machine it should act as if a physical card is present.

I have the current Xcode 9 beta, and I've created a completely new project based on Objective C so I can explore the NFC functionality.I've added the CoreNFC.framework in Linked FrameworksI've also added Privacy - NFC Scan Usage Description to my info.plistHowever as soon as I add:#import <CoreNFC/CoreNFC.h>I get an error - File Not Found CoreNFC.hAnyone know why I cannot add this framework to my project?[EDIT] Typical Apple the errors are not descriptive at all, you have to have a device plugged in, trying to build on simulator or even generic device for me fails to build the project. Once I plugged in the iPhone 7 the errors dissapeared [/EDIT]Plasma

IPhone 14 Pro - ios 17 Beta NFC tag reader no longer functioning as of ios15 update. I have updated to Beta 17 and still not working. Airfrop off, cellular data off and have completed several restarts. Any help with repairing is appreciated. Thank you.

According with the CoreNFC it's only possible to read NFC Tag and not emulate it. Then, how is it possible for the iphone send the credit cart virtual code to the POS?

Is it possible to write sequentially on multiple tags using NFC? e.g. I have 10 tags and in my app set the number of writing and pressing on a button start first writing on first tag. when wrote, start an other writting and so on....

Hi, does anyone know how to enable creating or configuring Near NFC Reader in SwiftUI? I've already added the capability, the permissions in info.plist, the entitlement, and the SwiftUI code, but without success. Here's the example code: class PaymentT2PViewModel: NSObject, ObservableObject { @Published var paymentT2PUIState: PaymentT2PUIState // MARK: - NFC Properties @Published var nfcMessage: String = .empty @Published var isNFCReading: Bool = false private var nfcSession: NFCTagReaderSession? init(paymentT2PUIState: PaymentT2PUIState) { self.paymentT2PUIState = paymentT2PUIState super.init() ) } func startNFCReading() { print(INICIO: startNFCReading llamado) guard NFCTagReaderSession.readingAvailable else { print(ERROR: NFC NO disponible en este dispositivo) Task { @MainActor in self.nfcMessage = NFC no disponible en este dispositivo } return } print(NFC disponible, creando sesión...) nfcSession = NFCTagReaderSession( pollingOption: [.iso14443, .iso15693, .iso1

Hi there. I am using flutter_nfc_kit (https://pub.dev/packages/flutter_nfc_kit) to make application that sends bytes to NFC module using tranceive commands, but really often system respond with error 500 or 103... Is there anything in this package that I can change for my commands to work fine? Cause now when I try to scan data it takes minimum like 30 seconds whereas on Android it takes like 7-10 seconds every time Thanks for any feedback

We have been struggling to get support and answeres regarding this roadblock : Request in whitelisting of the NFC Tag Reading and Writing (NDEF) entitlement for our iOS application Our application utilizes Core NFC to enable reading and writing of NFC tags, simplifying user interactions with NFC-enabled devices and services. The NDEF entitlement is essential for our app to deliver its core functionality effectively. Build Environment: Our app is developed and built using Xcode 16.4 on Codemagic’s cloud-based CI/CD platform, which utilizes a compatible macOS version (e.g., macOS Sonoma 14.4 or later). The app targets iOS 18 and uses Core NFC APIs for NDEF tag reading and writing. so far we cant get it to read or write as ios is restricking us

We are using an NFC tag that complies with ISO14443A and B standards (ISO-DEP) and supports ISO/IEC 7816 security. We are attempting to write some data using CoreNFC's NFCNDEFReaderSessionDelegate. We can detect the tag, but when we try to connect to it, it displays NFC Error (Tag Connection Lost). We also attempted NFCTagReaderSessionDelegate, but we were unable to detect the tag at that moment. Note that we have included the Privacy - NFC Reader Usage Description and ISO7816 application IDs for NFC Tag Reader Session to info.plist. Tag Reader Session Formats for Near Field Communication in entitlements.plist Can you advise on whether the problem is caused by the tag we're using? Or the CoreNFC library does not support writing? Thank you for your valuable time and assistance
