nfc

Hello,I moved to Xcode 11 and having an issue: deploying to a device with no NFC support, crash the app start up not founding CoreNFC framework.The same project worked fine with Xcode 10.I currently resolved including CoreNFC framework with optional flag but I thing there's a problem with Xcode 11 SDK.

Hi,I have difficulty to upload the application to AppStore just recently.This is the initial content of entitlement:<key>com.apple.developer.nfc.readersession.formats</key><array> <string>NDEF</string></array>The error message related to NFC capability:I add <string>TAG</string> into info.plist and entitlement.<key>com.apple.developer.nfc.readersession.formats</key><array> <string>NDEF</string> <string>TAG</string></array>Now the error message is:FYI, in profiles, I have enable NFC reader capability.Anyone has advise?

Our Goal : Program the M24LR16E NFC Tag which is manufactured by STMicroelectronicsAbout M24LR16E : Dynamic NFC/RFID tag IC with 16-Kbit EEPROM and ISO 15693 RF interface.We can find more details about M24LR16E here : https://www.st.com/content/st_com/en/products/nfc/st25-nfc-rfid-tags-readers/st25-dynamic-nfc-tags/m24lr-series-dynamic-nfc-tags/m24lr16e-r.html#resourceBy using Core NFC in IOS 13What we achieved : -&gt; We are able to detect the NFC Tag -&gt; We are ablate connect the NFC tag in the Philips driver. -&gt; We are able to get the system information from Philips driver like ( dsfid, afi, blockSize, blockNumber, icReference) -&gt; We are able to Present the passwordWhat we failed to achieve : -&gt; We are not able to read the data from NFC Tag -&gt; We are not able to write the data to NFC TagWe tried a lot to read the data from NFC Tag but we not able to succeed every

Hi everyone,After XCode11 released, I have been messing around with CoreNFC. And my sample app can detect some of NFC tags, such as my driver's licence and Felica cards. However, I cannot make it work to read my visa card, which is VISA EMV debit card with AID A0000000031010.I am aware of Apple's document saying CoreNFC doesn't support payment-related ApplicationIDs., but payment-related ApplicationIDs is a little bit confusing. I wonder the reason is technical limitation or I simply missed some settings.Any information would be appreciated.

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

Hi,As I understand the NFC write capability of iOS 13, it should be possible to exchange data with another device.- Am I right ?- Do you know about existing code emulating a serial protocol using NFC ?- What is the time between sending a minimal data packet and receiving an acknowledgement ?- What is the transfer speed to expect when sending data files ?- Do you know about existing apps doing this ?Thanks,Berle

Hello,does anyone know, how to check and transmit message from loyalty pass in your wallet when paying with apple pay through the payment terminal? e.g: You are buying shoes from store and when you are paying with apple pay and at the same time it checks and passes a message(id or something) from your loyalty pass in your wallet. (One tap experience, like it was said here https://developer.apple.com/videos/play/wwdc2016/704/?time=247)I only know, I need this NFC certificate and add nfc payload to a pass.How does it work and what else it takes to get that message from a pass?

Hi all, i'm new here, just started learning iOS in Swift, i have a project i've been working on and it involves NFC tags, I know that just recently with the release of iOS13 we can read and write to NFC Tags, i'm having an issue with the NFCTagReaderSession, I think my code is fine but when I run my app i get the following Error.Error: Error Domain=NFCError Code=202 Session invalidated unexpectedly UserInfo={NSLocalizedDescription=Session invalidated unexpectedly}I've searched everywhere and the few descriptions i've found tell me that I need to add a few things such as the Entitlement of Associatged Domains, so i went ahead and added applinks:example.comI have also added the following to my plist4<key>NFCReaderUsageDescription</key> <string>NFC Tag!</string><key>com.apple.developer.nfc.readersession.formats</key> <array> <string>TAG</string> </array>I'm using an iPhone X running iOS 13.1.2 and i am using xCode 11.1Does any

Hi, I'm developing an app that uses NFC, I've found out that when I set the NFCTagReaderSession alertMessage there is no accommodation of the message when the app is used with a large accessibility text size. Is there a way to set a specific font size on the alertMessage?The result i get with the maximum text size is like this:PS: there is an example image attached to my message but I am not able to see it

After having reviewed the information from the WWDC2019 Key Note on the NFC API~ https://developer.apple.com/videos/play/wwdc2019/715/I've been experimenting with the Sample NFC-Project as found at~ https://developer.apple.com/documentation/corenfc/building_an_nfc_tag-reader_appI've just been focusing on Read/Write of NDEF-Formatted-Tags,~ using NFCNDEFReaderSession, NFCNDEFReaderSessionDelegate, NFCNDEFTag, NFCNDEFMessage, and their related methods and propertiesand ISO7816-Native-Tags~ using NFCTagReaderSession, NFCTagReaderSessionDelegate, NFCTagI've had general success with API's for both technologies, but I would like to know if and how i can use theNFCTagCommandConfiguration class~ https://developer.apple.com/documentation/corenfc/nfctagcommandconfigurationwith those API's?I'm specifically interested in its maximumRetries and retryInterval properties.An example use case for me is with the Delegate-Callback for when the Reader-Session has invalidated~ tagReaderSession(_ session: NFCTagR

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
