nfc

Hi,Will iOS 11 allow NFC tags to be read when our apps are in the background, or only when they are in the foreground?Assuming background is supported, will the app wake up and become the foreground app (and the screen turn on) if the user swipes their locked phone over an NFC tag? Or will the user need to manually initiate something?I have a potential customer who wants to use NFC tags in a retail environment as part of a loyalty program. One thing the customer wants to do is subscribe the user to push notifications when they swipe a tag -- obviously this will involve some permissions UI the first time it happens. Is this going to be feasible?Thanks,Frank

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?

Does mobile NFC support copying Mifare cards

We have an iPhone and Android app that reads NFC tags. What we do is scan tags, get tag ID and put that into our database and add information. Works fine when scanned with Android. We went back and learned we had to program NFC tags to be NDEF. We did this, phone vibrates and can't upload into database. Does anyone have any input on this? Is there something we are missing, a certain thing we need to code them to?

Hello, is there a way to pass Data directly via NFC between two Devices (iPhones)? Example: iPhone 1: NFC- Writer iPhone 2: NFC- Reader iPhone 1 writes/ passes NFC Data to iPhone 2 which reads it. Thanks for Help

Has anyone managed to emulate a RFID / NFC tag with the iPhone? Either with Apple Pass / Pay, or CoreNFC? If so, how? We are looking at the MiFare standards, but any NFC emulation (like HCE for Android https://developer.android.com/guide/topics/connectivity/nfc/hce#ManifestDeclaration )

I saw that the Core NFC framework is only available for iOS and Mac Catalyst.Therefore is it possible to make a watchOS app able to read NFC tags?Best regards.

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:

When I generate passes with the new WWDC announced NFC tag: nfc : { message : “4444678966661234}I get the following error when loading it: Passes with an NFC dictionary must be signed with an enhanced Passbook certificate.How can I get an enchanced certificate?

Hi,is there any way to switch on the camera and read nfc tags in the same time?regardsNiki

Hi , I want to know that when apple supposes to support NFC Host Card emulation. is it supported in WWDC20?

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

Hello,I'm having a problem with using Xcode9 and NFC, basically when I create an NFC project with a provisioning enabled for its use, I do not see the capability on Xcode so I can not use the new API. Can you give me info about it? Consider I started from a new project and with NFC-enabled appID.thank you

Hi Guys, wanted to know if we can switch on/off NFC settings programmatically? or if we can take user to the settings in react native/IOS native programming ?

I have been trying to google around a lot for this, but unable to find anything. Is there any plan for Apple to open up SDK for NFC and allow developers to use NFC tags?
