nfc

I am having a lot of trouble getting NFC to work a second time. The first time using it to read works just fine, but the second time I try it gives me errors about the delegate method not being found. The exact error is this: [CoreNFC] 00000002 8093c3f0 -[NFCTagReaderSession didDetectTags:connectedTagIndex:]:141 Delegate does not implement -tagReaderSession:didDetectTags: method I know that the delegate is set because it is calling the same code. I do invalidate the session after reading. I have stepped through the code and made sure that line is called. Does anyone have any suggestions?

Hello Apple Developer Community and Apple Team, I want to raise awareness and gather support for an important feature request regarding NFC support on iPhone devices in Argentina. Millions of Argentinians use the official public transit card, SUBE, daily to pay for buses, subways, and trains. On Android devices, the SUBE app allows users to: • Check balance via NFC • Reload credit instantly • Confirm top-ups by holding the card near the phone • Use a digital version of the card (in some cases) However, iPhone users cannot use these NFC features because iOS currently does not allow third-party apps like SUBE to access the NFC chip fully. This limitation negatively impacts iPhone users, many of whom rely heavily on SUBE. I have submitted detailed feedback to Apple requesting the enablement of controlled NFC access for third-party transit apps in Argentina, starting with SUBE. I encourage fellow developers, users, and community members to support this request. Enablin

alguem sabe uma forma de obter o UID de uma tag NFC Usando Swift 4?how can i read and display the UID NFC Tag ?

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)

I have a digital body weight scale that I want to make IoT. Getting the weight shouldn't be an issue, but I want to feed that data directly to Apple Health, without an app in the middle. I was thinking about using either Bluetooth or NFC so when someone weights him/herself, it sends the weight data directly to the iPhone. Is this a capability? Could this ever be implemented in future iOS/Health versions? I can see how this would greatly increase the use of Apple Health by devices in-the-wild. Sending information directly to the device would greatly reduce both time and cost for a developer and keep it somewhat future-proof, while also removing constraints (having an app, registering an account etc) for the user. I imagine having some specific data packet for Apple Health data that could be transmitted via NFC or Bluetooth that would trigger an event on the user's device showing the data/data-type and asking him to allow/add it to his Health app.

Greetings, Question 1: I'm currently working on implementing a feature that involves tracking NFC tag reading events. Specifically, I aim to monitor these events for passes that have been added to the wallet using my application. This way, I can gain insights into the interactions users have with these passes and provide enhanced functionality based on their usage patterns. Question 2: Is there a way to implement a restriction on NFC-based passes, allowing them to be used only once for a specific action or purpose? I'm looking to ensure that once a user utilizes the NFC feature associated with a pass, the pass becomes inactive for any future interactions, thereby enforcing a one-time use scenario.

Hello. I have NFC tags that I scan before walking my dog, that set off a list of shortcuts. The shortcuts have been failing the last couple of weeks but were fine before that. seems to be a problem with linking to starting a walk in apple watch workouts?! I have the latest iOS 18 public beta running (18.1) and watchOS 11.0.1

I saw that Apple is opening up NFC to allow phones to do things like open doors etc which means they are allowing a way to do card emulation. I cannot find any info on this on their site with exception of the keynote when they discussed this. Is this going to be included in CoreNFC or is this something that Apple Wallet will do? Basically looking for a starting point on this as we need the ability to connect to an NFC reader by tap of iPhone.

Is it possible to send a URL from iphone to iphone via nfc, for example send the Wallet pass?

I'm facing issue on my NFC app such that the 'SendMiFareCommand()' API returns 'Tag Connection Lost' or 'Tag No Response' errors very frequently, especially on iPhone 12 and above, where 5G signal is weak. Since the issue doesn't appear on older iPhones or even on newer iPhones when they're put in flight mode, with exactly the same setup, we're certain that it has got to do something with the way iOS handles NFC function when 5G signal reception is poor. We even got this seconded from NFC tag manufacturers NXP and ST. So is there any way I can adjust priority / precedence of NFC function when 5G signal reception is poor? With 5G signal poor in almost all areas of the US as of now, this issue is pressing and affects the entire UX of my app.

Hello, I have developed an iOS application called DinecTag (be.dinec.DinecTag) with a developer account named Dinec International which is registered in Belgium, I received the NFC entitlement valid for Europe and my App is on the App store since some months (the App is used to open doors by presenting the iPhone in front of a special reader) The App is published only on countries inside Europe (it don’t work outside anyway) I would like my App can be used outside Europe, so I need another entitlement called NFC & SE Platform entitlementn to ask for that, I need an account registered in a country covered by that entitlement Dinec is a company that is member of the Lisam group Lisam has an apple developer account registered to USA, called Lisam Systems So I have asked to the owner of that account to add me as a developer in the USA team So when I connect to my developer account, I can switch between Dinec International SA and Lisam Systems on top right of the screen, I am member of the tw

We are using the CoreNFC API for reading the NFC tag of the locking components of our customer. We have not implemented the scan functionality within our app, instead we are using only the iOS built-in mechanism. Normally the NFC notification is triggered and the user can open our app which then handles the provided data. BUT if the wallet app on the iPhone has a valid credit card enabled, most of the time (but more or less randomly) the wallet app is triggered instead of our app. I checked the callbacks and we are not called by the iOS NFC mechanism in that case. My first idea was to update the AASA file on the server because of the changes introduced with iOS13. My question is if there are other possible solutions for this issue. At the moment our NFC feature makes only sense for users which have not setup the wallet. :-/
