“nfc”

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

We use CoreNFC feature for few clients. For clients who don't use NFC or add NFC related permission, the app is rejected on App Store. is there a way to make CoreNFC optional in the library and not lead to app store rejection for parent app who do not use this feature?

Here is my write NDEF message code: let readerWriter = NFCReaderWriter.sharedInstance() let payloadData = NFCNDEFPayload(format: .nfcWellKnown, type: U.data(using: .utf8)!, identifier: Data(), payload: google.com.data(using: .utf8)!) let message = NFCNDEFMessage(records: [payloadData]) readerWriter.write(message, to: tags.first!) { (error) in if let err = error { print(ERR:(err)) } else { print(write success) } self.readerWriter.end() } First Issue: When I want to read the NFC chip in the background without opening the app, I find the detection speed is not ideal. For example, this code writes google.com this time. When performing background reading, it does not successfully read every time the chip is near, and there seems to be a one-minute interval. Second Issue: When I implemented this method in the AppDelegate: - (BOOL)application:(UIApplication *)application continueUserActivity:(nonnull NSUserActivity *)userActivity restorationHandler:(nonnull void (^)(NSArray> * _Nullable))restorationHandl

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
