Good morning, I hope to find someone who knows better than me regarding reading NFC tags I'll explain what happens: if I read my card [iso 7816 nfc card with fingerprint reader] everything is fine. If I bring another card near it, for example the Italian tax code, it reads OK (so in the UI it says that it has been read) in the usual entitlement error log I honestly would prefer it to show the error: self.nfcSession?.invalidate(errorMessage: "Not a WiBioCard Otp Card") while I have precisely in the UI that everything went well.

Dear Apple Developer Support, I hope this email finds you well. I am writing to seek your assistance regarding an advanced NFC functionality we aim to implement in our existing iOS application. Our application provides a mobile access solution for businesses, eliminating the need for traditional key fobs by enabling door access via smartphones. We are currently working on a feature to unlock doors using NFC tags. The NFC tags will contain specific information for each lock, and users will unlock the door by tapping their iPhone to the tag. To enhance the user experience, we aim to: Bypass the NFC prompt that requires user interaction to confirm the NFC read. Unlock the door without needing to open the app. Our goal is to provide a completely touchless and seamless access experience for our users. However, we understand that there are certain security and privacy constraints in place. We are looking for guidance on: Any potential solutions or workarounds that would allow us to achieve our desired functionality. Possibilities for requesting special permissions or utilising system-level APIs to enable background NFC reading and actions without user interaction. We appreciate any assistance or recommendations you can provide to help us deliver a superior user experience while adhering to iOS security guidelines. Thank you for your time and support. Best regards, Pavez

Issue: Amtrak's state partner in New Jersey, SEPTA, has requested the incorporation of NFC suppression when an Amtrak mobile ticket is opened on their app. This feature ensures that NFC remains inactive and does not inadvertently bring up Apple Pay, Google Pay, etc., when customers are trying to scan their Amtrak tickets on SEPTA validators. Request: Amtrak is requesting to use the entitlement com.apple.developer.passkit.pass-presentation-suppression in our Amtrak app to suppress the display of Apple Pay passes when the app is in use. This is to prevent interference with the NFC reader during ticket validation, as illustrated in the attached screenshot from SEPTA's app, which shows a similar implementation with the message: "Payment cards and passes will not work automatically while NJ TRANSIT is in use." Entitlement Information: Entitlement Key: com.apple.developer.passkit.pass-presentation-suppression Boolean Value: YES Justification: The entitlement will enable the requestAutomaticPassPresentationSuppressionWithResponseHandler: method to keep the Amtrak app in the foreground when operating near NFC or other RF readers. This feature is crucial for ensuring seamless ticket scanning and validation for our passengers without the interference of Apple Pay or other digital wallets. Reference Documentation: For more information on this entitlement, please refer to the Apple Developer documentation: Apple Pay and PassKit Entitlements. Implementation: In our entitlement configuration file, we will add the following key: com.apple.developer.passkit.pass-presentation-suppression Supporting Evidence: The SEPTA app demonstrating the implementation of this feature can be found in the App Store. Amtrak seeks to implement a similar suppression mechanism, displaying the message: "Payment cards and passes will not work automatically while Amtrak app is in use." We seek Apple's approval for this implementation to prevent any potential rejection of our app store submission for incorporating this critical feature for our state partner's requirements. Thank you for your consideration.

I used NFC in my app, but When I iphone near the NFC device times the following error： 2024-07-15 14:10:24.882616+0800 TestNFC[1239:40733] [xpc.exceptions] <NSXPCConnection: 0x280d68e60> connection to service with pid 58 named com.apple.nfcd.service.corenfc: Exception caught during decoding of received selector didDetectExternalReaderWithNotification:, dropping incoming message.

We want to use HCE or Wallet to use the iPhone on NFC readers that start EV chargers. They use the same tech as transit systems (MiFare and ISO 14443-4), but the backend systems only use the NFC UID for verification. Is it possible to use HCE (CardSession) or Wallet (Transit card) to transmit a static UID? If so, could our use-case go under either In-store purchase, loyalty programme, or transit? Or are those categories very rigid as to their use case? The new EEU regulation seems to open up this a bit.

I am developing an APP, scan and read NFC Tag information. I can only get the message in the NFC tag, but I cannot get the chip information. Or rather, the information obtained is incomplete. Look at the code: NFCNDEFReaderSession *session; - (void)readerSession:(NFCNDEFReaderSession *)session didDetectTags:(NSArray<__kindof id<NFCNDEFTag>> *)tags API_AVAILABLE(ios(13.0)) API_UNAVAILABLE(watchos, macos, tvos) { NSLog(@"call back ios13"); if (tags.count > 1) { session.alertMessage = LocalizedString(@"ErrorTips4"); [session restartPolling]; return; } id firstTag = tags.firstObject; HBNFCNDEFTag *ndefTag = firstTag; NSLog(@"ndefTag == %@", [ndefTag valueForKey:@"_tag"]); dispatch_async(dispatch_get_main_queue(), ^{ [self invalidateSession]; }); } Obtain datas: ndefTag == <NFTagInternal: 0x283db5c00>-BA5A89060AA01FAB { Tech=Unknown Type=Unknown ID=(null), NDEF=4, capacity=137, messageSize=45 } An Other: NFCTagReaderSession *tagSession; - (void)tagReaderSession:(NFCTagReaderSession *)session didDetectTags:(NSArray<__kindof id<NFCTag>> *)tags API_AVAILABLE(ios(13.0)) { NSLog(@"call back ios13 tag"); if (tags.count > 1) { session.alertMessage = LocalizedString(@"ErrorTips4"); [session restartPolling]; return; } id <NFCTag> firstTag = tags.firstObject; HBNFCTag *nfcTag = firstTag; NSLog(@"nfcTag == %@", [nfcTag valueForKey:@"_tag"]); dispatch_async(dispatch_get_main_queue(), ^{ [self invalidateTagSession]; }); } Obtain datas: nfcTag == <NFTagInternal: 0x283dac900>-BA5A890699350585 { Tech=A Type=MiFare UL ID=0426226AB37381 silentType=0 SAK=(null) ATQA=(null) sfgi=0x0 } I need datas: Tech、Type、ID、capacity、messageSize、SAK、ATQA What shall I do?

Hi, I'm inquiring in regards to the feasibility or possibility of making a connection from iPhone to another, such that one iPhone uses Apple wallet, and another iPhone would detect for the signal within the app. Please let me know if this is feasible or if any more information would be necessary to assist. If this is possible, what documentation would be relevant? Thank you.

I have a client who asked me to create an app that reads nfc data, but this data needs to come from a built in iPhone nfc tag, so the app will read through nfc the SECOND device info. my question is, does the iPhone has a built in nfc tag? if so, can it share any device info?

We are developing an app for the online identification function of the German National ID Card. https://github.com/Governikus/AusweisApp https://apps.apple.com/de/app/ausweisapp-bund/id948660805 Currently there are two NFC timeouts we are not able to influence because there is no API. A NFC Session has a maximum lifetime of 60 seconds, independent from any card communication. When a card was detected the connection will only last for 20 seconds. Combined there is also something like a worst case: The user presents the card 55 seconds after the session was started: The connection will only last for the remaining 5 seconds of the session. The identifications works as follow: The user clicks on a link on a website and our app will appear. After selecting access rights the NFC session is started. Sometimes the user start to search for their ID card now and this takes some time. When the 60 seconds are over we start a new session until there is a card or the user aborts. After establishing a secure channel with a PIN our app is a tunnel to allow a server a direct communication with the card. This takes some time. There are many identification aborts due to the unpredictable timeout, which cannot be controlled either by the API or by the user. We also have a use case where the iPhone can be used as a card reader over WiFi by an app on another device. It is essential to have a permanent NFC session without timeouts, as long as the user wants it in this case. Any idea how to deal with this situation? How can we disable this timeouts?

I'd like to open a small window to play the GIF by scanning NFC tag, when app is unlocked. can I use app clips to realize it ?

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.

My app need a specific scene that play a video when my iPhone close to NFC Tags. and my app can read the data from NFC Tags, the data will tell us which kind of video can be play. I tried to write URLScheme or Universal Link in NFC Tags, but all this ways will pop up notifications. not launch my app and play a video, how can I design my app. please give me some advice, thanks!

I'd like to launch my APP via scanning NFC Tags In BackgroundMode. However, every time when I scan NFC tags, there always APP notification pops up, instead of opening APP directly. Please advise me how to skip the APP notification and directly launch APP.

Hi, I'm developing an app that reads the NFC tags. So far so good, everything worked as expected, the app reads the passports and the IDs, until we encountered the french ID issued after March 2021. My app has the following entitlements: <dict> <key>com.apple.developer.nfc.readersession.formats</key> <array> <string>TAG</string> </array> </dict> And this additional entries in the .plist: <key>NFCReaderUsageDescription</key> <string>NFC usage to scan ID chip</string> ... <key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key> <array> <string>A0000002471001</string> <string>A0000002472001</string> <string>00000000000000</string> </array> According to an article which I cannot link on this forum because the domain is not permitted, iOS started supporting this specific ID from version 16. When I look at the docs, I can see the .pace polling mode was added. I tried specifying this additional polling mode in my app like so: var pollingOptions: NFCTagReaderSession.PollingOption = [.iso14443] if #available(iOS 16, *) { pollingOptions.insert(.pace) } self.session = NFCTagReaderSession(pollingOption: pollingOptions, delegate: self, queue: nil) But when I try to start the session it gets instantly invalidated with this message: Missing required entitlement. I'm pretty confident the message is misleading and something else is missing somewhere, my bet would be on the .plist entry com.apple.developer.nfc.readersession.iso7816.select-identifiers missing one of the cryptic numbers, but I have no idea where this can be taken from. How do I implement this .pace polling mode, can someone give me some guidance?

Hi there, I am using Core NFC and I established the connection with the card, (it means that the info.plist is correct and the entitlement should be correct as well). The app detects the card, but after sending the command 'tag.sendCommand()' I receive this message: [CoreNFC] -[NFCTagReaderSession transceive:tagUpdate:error:]:879 Error Domain=NFCError Code=2 "Missing required entitlement" UserInfo={NSLocalizedDescription=Missing required entitlement} So, what is missing or what am I doing wrong? Here is the code: func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) { guard !tags.isEmpty else { return } let hexString = //... if case let .iso7816(tag) = tags[0] { session.connect(to: tags[0]) { error in if let error = error { print("Error: \(error.localizedDescription)") return } let apdu = hexString.convertToAPDU() tag.sendCommand(apdu: apdu) { (response: Data, sw1: UInt8, sw2: UInt8, error: Error?) in // -> here is when the error appears, in the completion print([UInt8](response)) // print -> [] } } } }

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: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.developer.nfc.readersession.formats</key> <array> <string>TAG</string> </array> </dict> </plist> I have added the following keys inside my Info.plist file: <dict> <key>NFCReaderUsageDescription</key> <string>Access NFC</string> <key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key> <array> <string>D2760000850100</string> </array> ... </dict> 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 command I end up with the response of 0B. Which does not tell me anything because it is not an official response. The Mifare command I am using is the select application command: 5A123456 where 123456 is the application ID. As mentioned before this works perfectly on Android. The only response I can get from the Mifare DESFire card is with an ISO7816 command: 00A4040006D2760000850100. Which is the select application command according to the ISO7816 standard. However, after executing this command I need to authenticate, which requires a complex algorithm. Is it necessary on iOS to first execute ISO7816 commands, before you can execute Mifare commands?

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<id<UIUserActivityRestoring>> * _Nullable))restorationHandler { if (![userActivity.activityType isEqualToString:NSUserActivityTypeBrowsingWeb]) { return NO; } NSLog(@"userActivity: %@", userActivity.ndefMessagePayload); if (userActivity.ndefMessagePayload) { return YES; } return NO; } I found that userActivity.ndefMessagePayload outputs null. At the same time, looking at its private variables, it seems to have values: Printing description of userActivity->_internal->_payloadDataCache: { "com.apple.corenfc.useractivity.ndefmessagepayload" = {length = 546, bytes = 0x62706c69 73743030 d4010203 04050607 ... 00000000 0000019c }; } If ndefMessagePayload is null, how can I determine that it is an NSUserActivity from an NFC scan?

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. Neither approach A or B provide optimal approach shown in Ideal flow. Is this expected from CardSession that there is no option to startEmulation without the action sheet? Is there a plan to improve startEmulation so that it could show "Hold near Reader" without the action sheet? Thank you.
