nfc

Hello, I’m working on creating an NFC-enabled Apple Wallet pass and I need assistance with the proper implementation of the pass.json file to include NFC functionality. My goal is to enable NFC interactions, such as tapping to unlock a door or interacting with other NFC systems. Here is what I have done so far: Set up a Pass Type ID and Certificates: I have registered a Pass Type ID in my Apple Developer account. I have generated and installed the required certificates (Pass Type ID certificate and WWDR certificate). Backend Integration: I have set up a backend service for generating passes, and I can successfully create and deliver standard Wallet passes without the NFC functionality. Adding the NFC Field: I understand that to enable NFC interactions, I need to add an nfc dictionary to the pass.json file. The key components for NFC include the encryptionPublicKey, message, and payload. Here’s an example of my current pass.json:

NFC reading starts but after BAC, during the reading of DG2 the NFC stops reading and returns with Tag connection Lost error . It almost fails everytime on iPhone 15 Pro max with the following error. What's the solution for this? This is really important because our app entirely relies on the NFC data to proceed forward. This always fails in iPhone 15 & 16. Same card works fine on older iPhone models. What change should we do or include for the newer models. Error Domain=NFCError Code=102 Tag response error / no response UserInfo={NSLocalizedDescription=Tag response error / no response, NSUnderlyingError=0x303bd6af0 {Error Domain=nfcd Code=29 Tag Error UserInfo={NSLocalizedDescription=Tag Error, NSUnderlyingError=0x303bd6910 {Error Domain=com.apple.nfstack Code=20 No response from tag UserInfo={NSLocalizedDescription=No response from tag}}}}}

I keep seeing this in the Xcode when I launch my app: -[NFCTagReaderSession beginSessionWithConfig:]:468 error:Error Domain=NFCError Code=203 System resource unavailable UserInfo={NSLocalizedDescription=System resource unavailable}, errorCode: 0xcb Initially, the device was working with NFC. Now on multiple complete restarts of my app, the System resource is still not available. If I lock the screen and reenter iOS again, the problem persists. Rebooting the device appears to get it working again. I suspect this is only happening on iPhone 15 and iOS 18.01. My other devices I have do not exhibit the problem. I'd wager some service in the OS has crashed? There also appears to be limitation on renewing nfc sessions. Similar problems on iPhone 16 to what I experienced on iPhone 15. I don't know what they did with iPhone 15 and 16 but the NFC has really deteriorated for longer sessions. Seems the newer Apple HW is worse at NFC than my iPhone 11. Just providing feedback. The devi

I am trying to find solutions past 4 days. but not getting any reference about NFC implementation in my app to read Debit/Credit card upon user consent? Can you confirm apple is provided any api for read Debit/Credit card using NFC or not. Tried with normal NFCReader but it reads only for normal tags but nothing with Visa/ MasterCard cards. Looking forward some help from you. Thanks

Hi, we are trying to get or set the NFC UID when doing HCE CardSession emulation, but can't find any way to either get the chip UID used in a session, or set it beforehand. Is that possible with a normal HCE CardSession eventStream received ADPU event? Or is another framework/product needed for this? We've done a Interoperability request (INTEROP-214), which lead us to using HCE. Our usecase is specifically interacting with EV chargers, that only support using the chips UID for identification. Can Apple Pay / Wallet be an alternative to do such low level handling?

I am experiencing an issue with NFC scanning on my iPhone 11 after updating to iOS 18. Previously, I was able to use NFC tags without any problems. However, since the update, the NFC functionality no longer works as expected. Installed OS: iOS 18.0 (22A3354) Here are the troubleshooting steps I have already tried: Opened the Shortcuts app. Tapped on Automation. Searched for NFC. Selected Run after confirmation. Tapped NFC Tag -> Scan. Unfortunately, nothing happens at this point; the NFC scan doesn't initiate. This issue has made it difficult for me to use NFC-dependent automations and functionalities that worked seamlessly before the update. Could you please provide guidance on how to resolve this problem? Thank you for your attention and support.

I have AppClip set up in AppStoreConnect and it is activated when read by NFC. After trying several times, sometimes the AppClip card does not show up. (I don't think it's a communication speed issue as it doesn't show up after some time). As for the cards, we are only aware of the AppStroeConnect settings. I tried changing the image file of the card to one with a reduced size, but that did not completely resolve the issue. If you have anything to investigate to resolve the issue, I would appreciate it if you could let me know.

Hello, I am developing an application that involves writing data to RFID tags using NFC (ISO/IEC 14443A/B, Mifare, and FeliCa standards) for an electric vehicle charging station. However, I am consistently facing an issue where the Apple Wallet app is automatically triggered during NFC operations on iOS. This problem occurs every time I attempt to write data to the RFID tags, preventing the application from properly detecting or interacting with the NFC tags. Here are the key details of the issue: Device: iPhone (tested on various models and iOS versions) Issue: Apple Wallet automatically opens during NFC tag writing operations. Expected Behavior: My application should write data to RFID tags without triggering Apple Wallet. RFID Standards: ISO/IEC 14443A/B, Mifare, FeliCa. Code Implementation: I am using the Core NFC framework and NFCISO14443ReaderSession to communicate with the RFID tags. The same code works seamlessly with Android devices, but iOS continuously t
