nfc

Hello, I’m developing an app and want to explore the possibility of using an iPhone to emulate an NFC tag. Specifically, I’m interested in enabling one iPhone to act as an NFC tag that another iPhone can read, creating a tap-to-interact experience within my app. Is this functionality supported by current iOS APIs, or is it something that might be available in the next update for iOS 18.1 which is supposedly unlocking iPhone NFC chips? If not, are there any workarounds or third-party solutions that can achieve this such as bluetooth low energy (BLE) maybe? Any insights or guidance on how to implement this feature would be greatly appreciated. Thank you!

Hi All, We are using a ST25DV NFC tag and Fast Transfer Mode. Our iOS app sends a custom command that sends some data as an input and expects a response from the tag that includes a payload of ~4000 bytes. We have successfully sent this command to the tag using the NFC Tap App on Android and received the full data response. However, on iOS (15.3.1-iPhone 12 Pro) as we loop through and get the response (256 bytes at a time), at random point during the reading of the response we get the following error: [CoreNFC] 00000002 80050360 -[NFCTagReaderSession transceive:tagUpdate:error:]:824 Error Domain=NFCError Code=102 Tag response error / no response UserInfo={NSLocalizedDescription=Tag response error / no response, NSUnderlyingError=0x283c3cde0 {Error Domain=nfcd Code=29 Tag Error UserInfo={NSLocalizedDescription=Tag Error, NSUnderlyingError=0x283c3c1b0 {Error Domain=com.apple.nfstack Code=20 No response from tag UserInfo={NSLocalizedDescription=No response from tag}}}}} We are not using .addres

Note:NFC detection part is in Cocoa Pods Framework. There is the solution to make NFC framework optional in the app to prevent this crash but in this specific case, NFC detection happens in the framework itself. It is crashing on all iPhones which don't have NFC support. Crash log for this:dyld: Library not loaded: /System/Library/Frameworks/CoreNFC.framework/CoreNFC Referenced from: /private/var/containers/Bundle/Application/9BF98F8A-775D-436A-92CA-4A6534686BF9/smart-interaction-client-iOS_Example.app/Frameworks/smart_interaction_client_iOS.framework/smart_interaction_client_iOS Reason: image not foundMessage from debugger: Terminated due to signal 6

Is there a standard for determining the tag type with CoreNFC?

We now want to take this a step further adding Rewards Enrollment via the terminal. So scenario is: customer pays with apple pay on adyen terminal we check if the customer has the NFC pass in the wallet if so, they earn points (regular flow which is working) if not, wallet asks if you want to onboard into the program. We use personalization.json for for this and a webservice from us We have everything setup, but the personalization isn’t working. We follow all these steps: https://developer.apple.com/library/archive/documentation/UserExperience/Conceptual/PassKit_PG/PassPersonalization.html The issue is that we never receive a POST request from wallet on the /personalize route we needed to set up. It simply never triggers. We tried to do it manually from wallet using the ‘Add Personal Info’ button that appears now (because we added personalization.json to the pkpass bundle), but this triggers a message ‘Unable to personalise pass’, while it should show the personalization fields with our logo on top.

During EEPROM reading or writing on some appliance devices, the app encounters an error after 6 steps. This issue occurs only on iPhone 14 Pro Max, 15 Pro Max, and 16 Pro models, while all other iPhone models function correctly. Any one with this problem?

HiI want to have sure. If I buy enrolling to Apple Developer Program as Individual client, will I get access to „NFC tag reading” option while creating App ID and use it while write app on Xcode? If yes, is any option while enrolling process which I must be selected?

About Core NFC enhancements in iOS 13: can we communicate with Java Card Applet?In a smart card gathering both Java Applets and MIFARE DESFire, we disabled the MIFARE capabilities on purpose. Using the proper AID and appropriate entitlements, we tried to communicate to applets, without success.Do you know when it will be possible to communicate with Java Card Applets?We saw that Core NFC documentation that they mention writing data will happen with ISO 7816, ISO 15693, Felica and MIFARE tags. Also, it is not supporting payment related AID. Our Applets AID are not part of those payment AID.Thank you

I'm having a hard time finding in the Wallet documentation what the net effect would be when the production signing certificate for a Pass Type ID w/ NFC expires out. I'm pretty sure any attempts to install a pkpass signed by an expired certificate will fail, but what I'm a bit unclear about is whether & how users who have already installed the pkpass previously while the signing certificate was valid would be affected. Will this already installed NFC pkpass signed with the expired certificate no longer be able to provide its function & so push notifications should be sent to attempt to update the pkpass with a new one that is signed with a currently valid certificate? Does the pass get removed automatically from Wallet or is the user notified in some way that the pkpass is expired due to the signing certificate?If anyone can point me at the documentation that covers this, I'd appreciate it.
