nfc

My application has the functionality to scan NFC cards. When I enable guided access and try to scan a card by starting the NFC session the Ready to scan alert is not shown. It is when I switch off guided access it is displayed on iOS.

I have followed the SoupChef example in migrating Custom Intents from SiriKit to AppIntents. However, we only require one iOS release back, so we can require iOS 17. Thus, I eliminated everything that was strictly for backwards compatibility, most notably the SiriKit Extension that required enormous amounts of code to try to coordinate with the real app which worked poorly anyway. I tested for example that an NFC tag Automation created in Shortcuts works to execute an AppIntent while the app is backgrounded. I am now receiving a beta report that indicates someone trying to execute one of our migrated AppIntents from their HomePod is not working, and they say it used to work sometimes (not all the time). I'm sure most such cases used to require the SiriKit Extension in the old SiriKit world. I am terrified that I may need to rebuild that monster once again when the new (to me) AppIntent API seemed so beautiful without it and seemed to work without it. The AppIntent API documentation seems to indicate

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.

After updating to iOS 15.4 I can no longer read any NFC tags. I believe Apple Pay is working fine. Replication: Unlock iPhone, hold NFC tag to top back of phone (without case or other magnetic or metallic materials nearby). Default iOS behaviour should be to read the contents of a known working tag (works perfectly on an Android device) and display a popup to manage the tag information (e.g. Popup would ask permission to open Safari to open a web link programmed on a tag) 3rd Party Tools: Previous versions of iOS 15 beta allowed read and write of NFC tags using apps such as NFC and NFC Tools. I have used normal mode, compatibility mode, have attempted to (re)format the tag to no avail. When conducting a read or write using these tools a popup appears, but no tag can be read or written. Ready to Scan popup remains open. Further steps taken: Hard Reset: No effect

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 requestAutomatic

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> *)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 == -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> *

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 establishi

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 customize local notifications contains GIF when my app scanning NFC tags and get different data from NFC tags.
