nfc

I'm trying to transfer data from one device to another using NFC. I'm trying to figure out if this is possible, I downloaded apple's sample project about CoreNFC, I was able to read NFC Tags (it wasn't a real NFC Tag, rather it was an NFC Tag emulated with an android device). Can I use my iPhone to emulate an NFC Tag to transfer data to another iPhone or Android device?

I am making an app that issues tickets within the app. How to issue a QR code pass there. How to create NFC path. How to authenticate NFC pass.(TouchID or FaceID) please teach me.

I want to create an app that will allow users to scan a NFC card of any type, and add it to apple wallet so it is digital. How would I create the source files for the pass within the app?

i want to fetch data from NFC tag and open App Clip i preferred link for NFC data reader but still my issue was not solve output like: NFC Ready: false Error Domain=NFCError Code=2 Missing required entitlement UserInfo={NSLocalizedDescription=Missing required entitlement} 2023-01-04 18:46:48.525435+0530 TapnClip[11544:7498529] [Default] Error requesting calls from host: Error Domain=NSCocoaErrorDomain Code=4097 connection to service named com.apple.callkit.callcontrollerhost UserInfo={NSDebugDescription=connection to service named com.apple.callkit.callcontrollerhost} Message from debugger: Terminated due to signal 9 can anyone help me to solve issue Thank you for support!

Hello Sir/Madam, In Apple Car Keys Specification R1 - Developer Preview 3 page 24, table 2-9, is mentioned the NFC Protocol Start parameter with the value of 5ms. Looks like this time was defined to include all the NFC procedures regarding protocol discovery and anti-collision, until the Select AID for the CCC applet command is issued. Quote: NFC protocol start includes all ISO 14443-3 commands required to setup the NFC communication (REQA, ATQA, AC, etc.).. This requirement seems highly unfeasible on our side. The typical time on some of our products is between 30-50ms for the NFC protocol link set up. This includes the unmodulated carrier time, the VASUP command, REQA/ATQA sequence, HLTA/WUPA/ATQA sequence, ANTICOLLISION sequence, SELECT device ID/SAK/RATS/ATS sequence, all of which impossible to fit in 5ms even if we reduce everything to back to back communication and no delays between commands. Can you further define what the NFC Protocol Start 5ms t

In testing out the Core NFC API~ iPhone 7, IOS 13.1,13.2With the Sample-NFC-Application available at~ https://developer.apple.com/documentation/corenfc/building_an_nfc_tag-reader_appI've occasionally gotten an Error, as reported by the Delegate-Callback for when the Reader-Session has invalidated~ readerSession(_ session: NFCTagReaderSession, didInvalidateWithError error: Error)of NFCError Code=203 “Session is invalidated due to system resource is unavailable”Once this error has triggered, it will continue to occur anytime another NFC-Scan is attempted.The error will then also occur for any other App that tries to use the NFC API~ e.g. NXP-TagInfo https://apps.apple.com/ca/app/nfc-taginfo-by-nxp/id1246143596Effectively killing NFC App functionality on the IOS-Device..The only way to stop this is to Restart the IOS Device.Here is a Stack-Overflow Post on the issuehttps://stackoverflow.com/questions/48172963/how-to-avoid-nfcerror-code-203-session-is-invalida

Hi folks, I have trouble with reading NFC tag in background while my application is running. I still receives a message in my iPhone 13, NFC tag of web Open donator.cz in application Safari. But I would like to open the app Donator which is here: https://apps.apple.com/dk/app/don%C3%A1tor/id6473955033 My NFC chip scanned by NFC Tools is ISO 14443-3A (NXP-NTAG213) In the tag is mentioned https://donator.cz/<8digits-number>**text In my Info.plist of application is: LSApplicationQueriesSchemes https://donator.cz com.apple.developer.nfc.readersession.felica.systemcodes 12FC com.apple.developer.nfc.readersession.iso7816.select-identifiers D2760000850101 Apple CDN looks like: https://app-site-association.cdn-apple.com/a/v1/donator.cz I have read in Apple documentation https://developer.apple.com/documentation/corenfc/adding-support-for-background-tag-reading that application should be in progress A Core NFC reader session is in progress.

Hi, We are developing an Enterprise SSO extension for use by our customers. It is working well for username/password. We would like to use external security tokens such as Yubikey, via NFC. This works well inside the container app. However, it looks like NFC might not be available to the SSO extension? The container app is signed with an NFC entitlement, and has the relevant key in the plist for a prompt to show the user. We use a 3rd party package called Yubikit to communicate with the Yubikey in the container app... all good. In the trial I did, I had the SSO appex configured as a Credential extension. I have a demo/sample host app that uses this service, that mirrors what our customer's apps will do. Currently, due to limitations in the server we are connecting to, instead of relying on a 401 authentication challenge, I am manually activating the enterprise SSO credential appex using ASAuthorizationSingleSignOnProvider, then our customer's host app will use the token the SSO appe

I'm trying to implement an app with NFC. I have to connect to MIfare tag. I'm notified in tagReaderSection function and the field tags contains a tag, but the value of this tag is [0] = (NFCTag) (0x40) Printing description of ((CoreNFC.NFCTag) (0x40)): ▿ NFCTag t- miFare : (lldb) and im not able to connect to it. In the info file I have add the string: com.apple.developer.nfc.readersession.iso7816.select-identifiers D2760000850101 nfcTagReaderSession = NFCTagReaderSession(pollingOption: [.iso14443], delegate: self) tttt tttnfcTagReaderSession?.begin() tfunc tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) { ttt tttt ttttif case let NFCTag.miFare(tag) = tags.first! { ttttttnfcTagReaderSession?.connect(to: tags.first!) ttttttttttt { What am I doing wrong?? thanks for the support PS: the NFC chip is Mifare Ultralight version 2 productType Ntag(04) [Xcode 12.0, IOS 13.0]

I am trying to use the NFC drivers to read multiple tags simultaneously, but there face hard limits: We cannot detect more than 2 tags. The analyze of the protocol implemented by NFC Core is incomplete. What is the development roadmap for a better multi-tag support?

My app need a specific scene that play a video when my iPhone close to NFC Tags. and my app can read the data from NFC Tags, the data will tell us which kind of video can be play. I tried to write URLScheme or Universal Link in NFC Tags, but all this ways will pop up notifications. not launch my app and play a video, how can I design my app. please give me some advice, thanks!

I am looking for something similiar to this function that exists in Android: https://developer.android.com/reference/android/nfc/Tag.html#getId()

Hi, I need to detect one iPhone to another iPhone using NFC. is this possible? if yes so pease explain how can i achieve this.

Dear sir, i am finding solutions past 4 days. but not getting any reference about NFC implmetent in my app for read credit card. please can you confirm apple is provided any api for read credit card using NFC or not. Thanks

Dear Community, We are in the process of developing a mobile banking application and have a key requirement related to NFC-based peer-to-peer (P2P) transactions. Our goal is to enable secure and seamless money transfers between two devices using NFC. Business Requirement: The application will provide a feature where users can initiate money transfers via NFC. The sender starts an NFC payment session from their device. Simultaneously, the receiver starts an NFC session to accept the payment. The sender's device should be able to detect the receiver’s NFC tag and process the transaction securely. We would like to confirm whether iOS supports such a use case. Your guidance on the feasibility of this feature, along with any technical or policy-related considerations, would be highly valuable. Looking forward to your response.
