Hi, I am integrating the HCE-based API into our SDK. Ideal flow It is bit tricky to support card change (step 3 below) after field-detect/double click due to NFC action sheet. Ideally, the flow is: User double-click. App launch Hold near Reader NFC instruction (optional) User change card User tap device to POS reader payment succeed. Approach A If I follow the code snippet in CardSession, where it calls startEmulation after readerDetected, I could change card before that. However, the Hold near Reader NFC instruction is shown very late, during tap. User double-click App launch (optional)User change card User tap device to POS reader Hold near Reader NFC instruction payment succeed. Approach B If I call startEmulation after sessionStarted, I could show Hold near Reader NFC. However, I could not provide the optional capability to change card anymore. User double-click App launch Hold near Reader NFC instruction User tap device to POS reader payment succeed.

I am developing a shortcut for an application that is currently in production. The shortcut essentially involves opening the application and launching a notification so that the AppDelegate initiates a process to scan NFC tags. To achieve this, I have an AppIntent that overrides the variable openAppWhenRun = true and an AppShortcutsProvider to implement this intent. The problem arises when a user updates to the latest version of the application and tries to implement this shortcut through an automation. The following error appears: When 'Reader' is detected encountered an error: The action 'Scan DMA tags' could not run because an internal error occurred. This does not always happen, only on some devices. However, if we uninstall and reinstall the application, it works perfectly. But this is not a viable solution since the application uses a database and data loss from frequent uninstallations is not acceptable. Any solution? I have tried to replicate the error but have been unable to do so. This issu

I have implemented NFC card reading functionality using NFCTagReaderSession. After starting the NFC reader session in landscape mode at least once, if I switch back to portrait mode and attempt to start the NFC reader session again, the scanning sheet does not respond to any touch interactions. Regardless of whether the screen is rotated, I expect the user to be able to close the reading screen, but it remains open. Is there any workaround for this issue? Code: class ViewController: UIViewController, NFCTagReaderSessionDelegate { func tagReaderSessionDidBecomeActive(_ session: NFCTagReaderSession) { } func tagReaderSession(_ session: NFCTagReaderSession, didInvalidateWithError error: any Error) { } func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) { } override func viewWillTransition(to size: CGSize, with coordinator: any UIViewControllerTransitionCoordinator) { super.viewWillTransition(to: size, with: coordinator) let session = NFCTagReaderSession(poll

Hello iPhone xs for testing XCode 15.3 I've successfully managed to select the AID and send other commands to a SmartCard using the following code: class NFCReader: NSObject, ObservableObject, NFCTagReaderSessionDelegate { func startNFCSession() { session = NFCTagReaderSession(pollingOption: [.iso14443], delegate: self, queue: nil) session?.alertMessage = Hold your iPhone near the NFC tag. session?.begin() // Start the session } func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) { guard let tag = tags.first else { // Safely unwrap the first tag session.invalidate(errorMessage: No SmartCard detected.) return } session.connect(to: tag, completionHandler: { (error: Error?) in if let error = error { session.invalidate(errorMessage: Unable to connect to SmartCard: (error.localizedDescription)) return } switch tag { case let .iso7816(iso7816Tag): self.sendAPDUCommandSelect(to: iso7816Tag) self.sendAPDUCommand_2(to: iso7816Tag) default: print(Not iso7816 type) // Update the Swif

Is there a way to access the Core NFC Framework from within a watchOS app?

I am following this code https://developer.apple.com/documentation/corenfc/building_an_nfc_tag-reader_app to implement a simple scanner for NFC. Now whenever I scan I am always getting connection to service with pid 60 named com.apple.nfcd.service.corenfc: Exception caught during decoding of received selector didDetectExternalReaderWithNotification:, dropping incoming message. Exception: Exception while decoding argument 0 (#2 of invocation): Exception: decodeObjectForKey: class NFFieldNotificationECP1_0 not loaded or does not exist>. this error. It always calls this function func readerSession(_ session: NFCNDEFReaderSession, didInvalidateWithError error: Error)

Hello everyone Together with a team of students, we have developed an application for android, a pass system that works using NFC, tell me if it will be possible to release a similar system on iOS. It's just that payment using NFC does not work in Russia. In our case, payment is not necessary, the NFC chip is used to transmit the signal to the reader. I would be very grateful if you could tell me if it will be possible to release our application in the App Store

Hello All, I am new to iOS development and would like to detect the smart card readers connected to USB-C port on iOS (16+) devices. The smart card reader is a custom hardware and not MFi certified. So as per my understanding, I cannot use ExternalAccessory.framework without MFi certification. Correct? How else can I achieve this? Does TKSmartCardSlotManager works for this purpose (or is it only for NFC devices?)? Is there any example for how to use this interface? I couldn't find any example for this as a starting point... Thanks in advance.

Hello all! I have an app (Scriptio Medication Management) that uses NFC on iPhone, and that works really well. However, I need a larger screen to satisfy customer requests (reports, etc). Because we use NFC tags to authenticate & authorize I need to stick with this tech. I cannot assume that all my customers have iPhone (we also deploy to Android) so pairing an iPad with an iPhone doesn't work for us. I was looking at an external device such as FlowJack, but since iPad no longer has an audio port, this won't work for me. Has anyone been able to solve this type of issue? Ideally I can find a solution that non-technical folks can attach/pair with an iPad to read NFC devices (NOT payment processing). Thanks in advance
