Hi,we have a specific need to listen to CoreLocation's didRangingBeacons and for the NFC tag simultaneously.Logic description:- we are listening to the didRangingBeacons- we have specified a RSSI treshold for the beacon and for running a NFC session- when the RSSI is reached for the NFC we show its popup but still listening to didRangingBeacons in case of we catch earlier beacon communication rather than via NFC with the tag - to conclude, we are open for both Beacons and NFC simultaneously and want to catch whichever of them which will communicate earlier with the phonecase 1If we fire the NFC session we are still listening to didRangingBeacons. If we catch communication with a beacon before the tag via the NFC then we continue with the beacon and invalidate the NFC sessioncase 2If we catch the communication with the beacon then we do not run the NFC session at all.The problemFrom time to time, the NFC is going to be br

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.

I've written a small test app to bring my understanding of CoreNFC up to snuff. The app just reads a tag and writes a simple string to it. The app has NFC entitlement, NFC privacy statement as required.The app reports the tag has read/write capability.When I read the tag message with NXP's 'TagWriter' app it states This is a test + current date. This is what I expect. When I read it with the app I wrote I get two chinese characters obscuring the first character i.e. capital 'T'. E.g. <chinese>his is a test 2019-12-18 03:27:08. This is the method I use to extract the text:func printNDEF(_ messages:[NFCNDEFMessage]) { DispatchQueue.main.async { for message in messages { for record in message.records { if let string = String(data: record.payload, encoding: .utf16) { print(MSG:(string)) } } } } }So please enlighten me what I do wrong here? Why is that first 'T' replaced by chinese whereas the NXP app does this correctly?Then when I write to the tag the same string but with updated date/tim

Now Safari send the U2F Reg/Auth commands in Extended length APDU command format for this feature through NFC.https://fidoalliance.org/specs/fido-u2f-v1.2-ps-20170411/fido-u2f-nfc-protocol-v1.2-ps-20170411.htmlIs it possible to use short APDU instead ? I see below api is allowed to change this mode.https://developer.apple.com/documentation/cryptotokenkit/tksmartcard/1773460-usecommandchaining

Good morning everybodyI'm triying to read badges from my iPhone. To start with NFC I've downloaded the Sample Project NFCTagReader. I followed exactly the recommandation of the tutorialAdd the NFC Tag-reading feature to the App IDAdd the NFC Tag Reader Serssion Formats Entitelement to the entitlement fileAdd the NFCReaderUsageDescruîption into the info.plistI was able to build the application, install it on my iPhone (XS Max, iOS 13.3) and run it.When I click on the scan action button the session starts (popup Ready to scan with the small animation). First issue, at this step I should see the reader description message I put in the info.plist file, but it dosen't display. After this I try to read my badge but it seems not to read anything. DidDetect callback is never invoked, and after 60 sec, DidInvalidate is called with a timeout error.The badge I try to read is a MyFare 4KI proably miss something, so could somebody help and give me the gidelines or link to sample code, it would b

I tried FIDO2 registration on webauthn demo site provided by yubico.But when I start registration procedure, follwoing pop up message was shown and nothing happend after that.Inser your security key or bring the key near the top of your iPhone.Then, activate the key.I used iPhone(iOS 13.3, Safari 13) and Yubico NFC security key.Is there anything that I need to do on iOS to activate security key?Please tell me if you know something about this.

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'm in the process of exploring using Passkit to host and distribute our University Digital ID card. I understand that Apple has worked with a few Universities in this Vertical and that there is a means to apply for this program. The only issue is that we don't have a one card solution, and our cards aren't distributed through Blackboard. We would like to handle this ourselves though with NFC readers deployed at strategic locations throughout campus (i.e. the Library, shared printers (Where students are required to swipe their ID's to release print jobs) as well as Dining locations, where they use their ID cards for a declining balance.Is there a way to work with Apple to get an NFC certificate for this using the system I described (barring having to work with Blackboard)?

Hello,I am currently writing a little prototype using CoreNFC and NFCTagReaderSession with ISO15693 tags.I have a custom command that takes some data as an input and expects to get output data from the tag.I have successfully sent this command to the tag using the app NFC Tools on Android and received the data that I've expected, but fail to get the same response on iOS 13.3.1. All I get is this error:[NFCTagReaderSession transceive:tagUpdate:error:]:735 Error Domain=NFCError Code=102 Stack Error UserInfo={NSLocalizedDescription=Stack Error, NSUnderlyingError=0x282454150 {Error Domain=nfcd Code=10 Invalid Parameter UserInfo={NSLocalizedDescription=Invalid Parameter}}}Why does this command work on Android but not on iOS?The command lies within the range of valid custom commands (0xA0 to 0xDF) for ISO15693 tags.Has anyone experienced similar issues? Maybe someone can share some learnings. I am grateful for every piece of information or any help.Kind regards.

Description:We are using the `read NFC tag in background` functionality but we are also reading the tags in foreground mode.If we do the Tag scan with NFC, having the app opened (in foreground), we also receive the notification about the scan result comming from the background read functionality. In result, we are experiencing the Tag read completion twice at once being in foreground mode: from foreground read and the background listener.Step-by-step instructions:1. Setup the `NFC background read` listener and the `NFC foreground read` functionality2. Open the app3. Run the NFC session4. Move the iPhone towards the Tag to read itResults we see:The Tag is being read but we are also receiving the notification from the `background NFC reader` at the same time.Results we expect:If the user is in the foreground mode, the app is opened, and he reads the tag, we expect not to receive the notification from the background NFC listener. The notification fro

I'm using Core NFC framework in my app. We need to read credit card number, expiry date when I tap the NFC Credit card on the iPhone on which my app is installed.I see Apple UI presented in my app which asks to readnearby NFC. But when I tap my contactless credit card on the iPhone it never reads or detects NFC. However it reads other NFC Tags seamlessly.Am I doing something wrong?
