nfc

Hello, I need to use NFC for a project. My problem is that always when im entering with my Phone a RFID field Apple Pay shows up instead of just my NFC application. I know that you can suppress Apple Pay with adding com.apple.developer.passkit.pass-presentation-suppression to the Entitlements File but my Problem is that this Entitlement also suppresses NFC which I need. How can I suppress Apple Pay but use NFC? Thanks for Help!

When i write text record on nfc tag, sometimes success but sometimes gives me error below. Error: Error Domain=NFCError Code=401 Stack Error UserInfo={NSLocalizedDescription=Stack Error, NSUnderlyingError=0x2822f9a10 {Error Domain=nfcd Code=21 writeNdefData:toTag:error::360 UserInfo={Line=360, NSLocalizedDescription=Connection Closed, NSDebugDescription=writeNdefData:toTag:error::360, Method=writeNdefData:toTag:error:}}} I don't know why this error sometimes occur. What is the meaning of Connection Closed? And how can I solve the issue?

I stumbled across the Apple NFC & SE Platform while searching for the cause to a persistent missing entitlement error. I am curious if not having this entitlement could be the root cause to my issues? Specifically, I am trying to perform an HMAC-SHA1 challenge-response via NFC on a YubiKey. Part of this entails low level APDU Send commands via NFC. The missing entitlement occurs right after the APDU Send. Per my separate post, I believe I have exhausted all other possible causes to no avail. For reference and details, this is the other post: [https://developer.apple.com/forums/thread/791995)

Hello.I want to make a Reward pass with NFC, but I'm curious about how to issue Enhanced NFC Certificate from Apple. What's requirements for issuing that? I'm not yet employed, then am I not qualified to develop NFC-enabled pass?Is there anyone to tell the detail requirements for it?

Can we write NFC Tag with password in iOS? That means iOS can Read/write to NFC tag with password protection? If yes then can you please share with me some details?

I'm developing an app which uses NFC read, but would also like to be able to write.I know Writing to NFC is not currently supported, but i was wondering if/when this functionality will be released

Hi, I am using the below code to detect if NFC is enabled or not. (BOOL)isNFCAvailable { if ([NFCNDEFReaderSession readingAvailable]) { return YES; } return NO; } I have also added the permission is info.plist file NFCReaderUsageDescription Detecting if NFC is enabled or not I am testing on iphone XS with ios 15.6.1 and on iphone 11 with ios 13.2.2. In both the cases, the API is returning false. Can you please let me know if I am missing something.

Hi together, i am working with the new CoreNFC library using ISO7816.I also are pretty new within the apple world and have two talking points regarding the NFCReader session handling.My use-case uses longlasting sessions with the card. However the NFCSession invalidates after about 20 seconds.Is there a way to extend the duration by setting a arbitrary timeout ? I cannot find any calls in the api regarding this.Secondly I may need user interaction while the session with the card is active. If i start the session ios shows the nfc overlay and blocks my UI thread until finished. Is there a way to manage the UI in an arbitrary way during NFC sessions?Sincerely

Hi Guys, if we use our NFC Chip (Background Scanning) with our domain xyz.tld/pages (NFC with URL) than we get following Error: CPSErrorDomain error 2. If we use other URL, than it's works fine, for example, following URLS works fine: xyz.tld xyz.tld/ xyz.tld/page xyz.tld/page/xyz xZz.tld/pages But if we add: xyz.tld/pages xyz.tld/pages/xyz than we got the error CPSErrorDomain-Error 2 we also tried (with different tld) xyz.tlx/pages or x.xyz.tlx/pages (Subdomain, www. to) what works fine.... It makes no sense? Or apple blocked our domain? Scanning with Iphone X or other normal NFC Reader are not a problem and works fine, only Background scanning have this issue. This happen only with background scanning on iOS 14.1 (iphone 12 pro ) and ios 14.4 (18D5030e) (iphone 11 pro) with iphone X 14.1 (18A395) native NFC Scanner it works fine.

Hi I’m hoping that someone can give me a definitive answer on this as if it is not possible then I will need to look at other possibles ways around it. I am developing an app that will need to check regularly whether an NFC tag is nearby but it won’t be convenient for the user to accept the notification every time, is there a method I can implement so the user can accept the permission to scan the NFC tag passively in the background without showing a notification?

I notice that there are two types of nfc session: NFCTagReaderSession this session in order to get tag's basic info like uid/type which call back function is tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) NFCNDEFReaderSession this session in order to get ndef message in tag which call back function is readerSession(_ session: NFCNDEFReaderSession, didDetectNDEFs messages: [NFCNDEFMessage]) My problem: How can i get tag's basic info and tag's ndef message(if it exists) simultaneously in one session or in one callback function.

Hi, i have a application that has textfields on UI. I can share this textfield's texts with using NFC on RFID card. I want to share this without using rfid cards, is it possible to share this texts with only using two iphone? For example, 1 iphone will be a reader, and other one will be a writer. Both phones are using same application. Read and Write nfc buttons are stay in application.

Hello, im trying to call from my View Controller a NFC Reader in a different ViewController. The NFC Reader starts but doesn't calls: func readerSession(_ session: NFCNDEFReaderSession, didDetectNDEFs...) I can call the NFC Reader in the other ViewController but don't use reader output because i think, that he doesn't calls the didDetectNDEF function. Thanks for Help

I have an NFC door, but I always have to enter a pin, and I have thought, Can I unlock this using an NFC on my Apple Watch, Apple AirTag, or iPhone, since they all use NFC? It seems it would save so much time, yet I do not know if there is an app/program that I could use, much less how to program it to trigger. Please reply if you have a response.

HiHow long does it take to get an NFC Certificate from Apple? So that we can delivery NFC Enabled Loyalty Passes.We registered at the following address but haven't received any communication for over 2 weeks.https://developer.apple.com/contact/passkit/We are developing solutions for our clients and need to test the technology.We use different PassTypeIDs for each of our Customers so it's likely we will need a different NFC certificate for each of our customers.How do we get NFC Certificates in bulk so that we can deliver NFC Loyalty Programmes to our Customers?Thanks
