Hello, I'm trying to read custom NFC (13.56mhz) tags with my iPhone using an NFC app, but none of them seem to be working (I've tried the three most popular NFC apps). I am writing text to these tags using a RC522 connected to a Raspberry Pi. I know that my scanner is working because I can read and write text to tags. I know NFC on the iPhone is working because the scanner also detected the signal when I opened and activated Apple Pay. Besides that, I am using known-good tags (such as a hotel room key) that also work with my scanner but not my iPhone. Has anyone else encountered this issue? Is there a solution? Thanks.

Guys, I need your help, please. What do I need: to get the tag's UID (i.e Serial number) using iOS app What do I have: I have an app Flutter, which works fine on Android (I can read the tag's UID) and do nothing on iOS The card's details (plastic card): Tag type: ISO 14443-3A Technologies available: NfcA, MifareClassic, Ndef Serial number: AB:BF:88:AE (this is i really need to get from the app) Saved message on the tag: My text with spaces On iOS side I created two implementations: one for NFCTagReaderSession, another one for NFCNDEFReaderSession (I do not use it at the same time, only separated) NFCTagReaderSession import UIKit import Flutter import CoreNFC @available(iOS 13.0, *) var session_tag: NFCTagReaderSession? @available(iOS 13.0, *) var flutterResult: FlutterResult! @available(iOS 13.0, *) @UIApplicationMain @objc class AppDelegate: FlutterAppDelegate, NFCTagReaderSessionDelegate { override func application( _ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.La

We need to integrate the Digital Card Rfid functionality into the app to allow our users to be able to recharge electric vehicles using NFC functionality. Last year we received a block from Apple because to enable the NFC capability it was mandatory to have integrated the ApplePay SDK within the app. We would like to understand if this constraint is still present and, if necessary, identify a solution to make our current Payment Hub (coexist (web interface for managing / adding payment methods) with Apple Pay.

Hi, I'm trying to read the tamper status from a NTAG 213 TT nfc (mifaretag - ultralight). Every time I do a sendMiFareCommand I get an error Tag is not connected. I can read the tag using an app called NFC tools and it shows the tamper status just fine. This is my code: guard tags.count > 0, let tag = tags.first else { session.invalidate() return } print(asd tags count (tags.count) isAvailable (tag.isAvailable)) switch tag { case .miFare(let miFareTag): print(asd family (miFareTag.mifareFamily)) let readBlock4: [UInt8] = [0xA4, 0x00] print(asd 1) if #available(iOS 14, *) { print(asd 2) miFareTag.sendMiFareCommand(commandPacket: Data(readBlock4)) { (result: Result) in print(asd (result)) switch result { case .success(let response): print(asd bem aqui 1 (response)) case .failure(let error): print(asd 1 Read tag error: (error.localizedDescription). Please try again.) } } } else { print(asd 3) miFareTag.sendMiFareCommand(commandPacket: Data(readBlock4)) { (response: Data, optionalError: Error

Since iOS 16, all identifiers not registered in Info.plist file as com.apple.developer.nfc.readersession.iso7816.select-identifiers seems to be accepted by the application when reading NFC card. Before iOS 16, the OS immediately rejects the NFC communication. Do you known if it's a simple bug or a modification of the NFC Card Reading feature ?

In Guided Access mode, Ready to Scan dialog does not appear when NFCTag Reading starts. Ready to Scan dialog does not appear but my app reads NFC tag. Is there a way to show Ready to Scan dialog? or is this correct behavior as iOS app? Best regards

International Domain Names allows non ascii character of non English languages in domaine name and then in email addresses. For many years IDN were correctly handled both on MacOS and iOS. This is no longer the case. iOS Another poster already reported on this forum that IOS mail is no longer able to send mail from an IDN email address, always displaying an incorrect message about an invalid address. This poster only had general incompetent advice from an Apple poster about checking his email account configuration. As this poster already reported an IDN account with worked previously no longer does. I can't date precisely which release of iOS regressed. iOS 15 for sure, 14 possibly. MacOS Since yesterday, I spend time trying to figure out why my S/MIME certificate no longer worked on my Mac, for the same IDN email account. After many test I figured out a partial workaround : the S/MIME certificate is setup with the punnycode form of the IDN domain adding an identity preference for the certificate did no help

After upgrading to iOS 16, the code below that I have to read the NDEF contents of an NFC Forum Type 2 Tag now returns an empty string. When running the same code on my iOS 15 device, this code works perfectly. When downgrading my iOS 16 device to iOS 15, this code works perfectly again. I can't find any documentation regarding changes made to CoreNFC in iOS 16 that would be affecting this, can anyone shed any light here please? func readerSession(_ session: NFCNDEFReaderSession, didDetect tags: [NFCNDEFTag]) { print(did detect) let str: String = nfcWriteContent if (tags.count > 1) { let retryInterval = DispatchTimeInterval.milliseconds(500) session.alertMessage = too_many_nfc_detected.localized() DispatchQueue.global().asyncAfter(deadline: .now() + retryInterval, execute: { session.restartPolling() }) return } let tag = tags.first! print(reading...) tag.readNDEF(completionHandler: {(ndefMessage: NFCNDEFMessage?, error: Error?) in var res = if (ndefMessage == nil) { // EVERY NFC SCAN ALW
