nfc

Hello, i cant seem to find an answer, on how i can achieve, that i get the Invocation URL and Location (to check if it is in the CLRegion) a second time (when the app is still running, but a new NFC Tag/App Clip Code is scanned). When the user first starts (or after closing it in the App Switcher) the App Clip, the Location and URL is checked in the SceneDelegate function func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions). But i cannot find a way to get the NSUserActivity on the next Invocation, if it is opened by a NFC Tag or Code. Is there a way to get the new connectionOptions (UIScene.ConnectionOptions) through the sceneWillEnterForeground function? My usecase would be, that the user may encounter multiple App Clip Codes, which he scans and in between these scans, he/she may not close the app fully.

Hi all, While trying to format blank ICODE SLIX or SLIX2 tags with my iOS swift own app, I cannot manage to have NFCTagReaderSession detect the tag. The NXP's NFC TagInfo App does detect the empty, factory blank, tag but my app fails Even the Apple's NFCFishTag demo app of WWDC 2020 fails to detect the blank tags My app displays the standard iOS NFC scanning panel but that's all it can do ... it keeps waiting to sense a tag, before timing out. AFAIK I properly set the entitlements (with both NDEF and TAG formats specified) and info.plist (with scan usage description string) files I have spent countless hours on Internet without success Any helps is much appreciated

I recently purchased some NFC cards and I want to use them to unlock my iPhone. Unfortunately, I have not found a way to do so. If this is not a feature in iOS right now, could we add this to a future version? If I can do this in the most recent version of iOS, please let me know how. Thanks!

My app is handling App Clips from QR codes and NFC tags. When an NFC tag is scanned, App Clip Card pops up. I can enter the application - no problem here. While application is still in foreground, NFC tag is scanned again. In iOS 13 it would mean that additional system notification is placed on top of the screen, this was inconvenient but not intrusive. In iOS 14 I can see almost entire app screen taken over by App Clip Card. I would expect the system to detect that app is already opened and disregard the App Clip Card invocation. Is it configurable to disable popping up of an App Clip Card from MY OWN app? Or should I file a bug?

Hello, I tried to build an NFC App and it works still fine - beside one big problem. When I want to describe a newly purchased NFC tag with my app, this does not work with the error code: ERROR: NDEF tag does not contain any NDEF message. However, if I open another NFC app from the AppStore, it works perfectly with the tag. It is also strange that once I have written a text to the tag with another NFC App, my app now works perfectly and I can now write to the tag. So my question is, why can I only write NFC tags with my app that already contain a message? I would also be interested to know how I could programme my app so that it can also write to empty tags. Since this also works with the other app from the AppStore, it must be possible with iOS. Many thanks in advance to all those who take the time to deal with my question.

I am developing a Java app that integrates with SmartCard reader. One of the features that I try to implement is reading/setting terminal (card reader) configuration without a tag being present on the reader. This can be done by sending so called escape codes. But to enable these escape codes we need to enable them in the driver. In case of macOS this will be SmartCardServices and the file that I should edit is: /usr/libexec/SmartCardServices/drivers/ifd-ccid.bundle/Contents/Info.plist I need to set ifdDriverOptions property to 0x0001. This procedure was described in this helpful GitHub comment https://github.com/pokusew/nfc-pcsc/issues/13 I tried to follow other instructions provided there but I hit the wall with read-only file system error. I wonder if there is an idiomatic way to change these settings. Why this is important? Sending new configuration via escape command is the only way to un-brick terminal that was (by mistake) wrongly configured.

This is on IOS 14.4 on an iPhone. When invoking an NFC Reader from the second tab of a tabview, when the NFC popover is displayed, the tabview goes back to the first tab. Then when the popover is dismissed, the user is left on the wrong tab. Does anyone know why this happens and how I can continue to show the second tab?

Hi, So I know Apple supports a few schools right now with student IDs in the Apple Wallet, my school isn't supported and probably won't be for a long time since they don't use Blackboard. So what I'm wondering is if it's possible for me to develop my own app to use the NFC code on my Staff ID to where I can put that pass into AppleWallet to use with the HID access control readers we use to get into buildings and other secure areas. I know I will have to get the PassKit cert from Apple, but I was wondering if this is something that could actually be done where I can just have the phone output it in express mode or something like that. Thanks ccs46

Hello I am new in apple developer and I would like to know if I can make a loyalty program for my business using apple wallet.

I'm designing a Bluetooth Low Energy accessory without a built-in display. According to the Bluetooth Core Specification (CSv5.0 | Vol. 3, Part H, Table 2.8), that limits pairing to Just Works pairing - which is unauthenticated and has no man-in-the-middle protection even with LE Secure Coonnections. However Section 2.3.5.4 (CSv5.0 | Vol. 3, Part H), states that an out-of-band pairing mechanism may be used to send the TK (temporary key) if both devices support it. That would provide authentication (i.e. MITM protection) beyond Just Works pairing. There are a number of white papers about implementing out-of-band pairing through the NFC radio (e.g. one from 2014 from the NFC Forum). So this is not a new concept. Searching through the forums, I have been unable to find a definitive answer as to whether or not iOS supports OOB pairing through NFC: This same question - https://developer.apple.com/forums/thread/15286 was asked five years ago and unanswered. As of two years ago (which may

Using iOS or Android NXP Tag Info or and NFC app we were not able to read or detect iOS Virtual Cards (Transit Passes) saved in Wallet. Can any one chime in on how to read virtual cards from Wallet? Please suggest.

My app access the invocation URL by : application:continueUserActivity:restorationHandler: (use UIApplicationDelegate). I found that if I take a screenshot when App Clips is open in the foreground, it will run the same function as above and pass the same userActivity as I open App Clips with App Clips Code or NFC tag previously. Is that normal? How can I differentiate whether user is opening App Clips by NFC tag or just taking a screenshot?
