I found my way to your configuration for my project, I can't find in the official version of iOS11 and Xcode 9 on the card to read any information, I would like to ask you about, in a formal environment, your project has a special configuration of others?

I got the app running but my iPhone 7 Plus does not recognise tags. Tried all my tags on a Pixel Phone and they are all working. Even rebooting like @tinue suggested does not work for me. Your code looks fine to me. Hopefully it gets better in Beta 2.

On Android that was possible for a while, but if it is finally possible on iOS 11.
Note that some passports, like US, needs to be open for NFC chip to be read. Also, to read the data on passport's chip you need to provide input information found in MRZ zone.

Some apps, namely NFC Tools from wakdev and NFC NDEF READER https://itunes.apple.com/us/app/nfc-ndef-reader/id1286248064?mt=8 manage to show UID and TagType - see screenshots.
Any idea how to access these properties ?

CoreNFC seems to have not changed much in iOS 12, (I guess the rumors were wrong).

There is one change in the header files, a NSUserActivity.ndefMessagePayload:
The NFC NDEF message with an Universial Link object that triggers the application launch.
See here.
Seems to indicate that you could register for your application to launch when a tag is scanned (from where???) with a specific NDEF message payload.

Anyone have any more information on this?

Hi!
I tried every tag I could grab nearby. They are elevator key, starbucks member card, subway ticket.
All failed... 😫
All these tags are readable by Android and according to the app NFC-Tool, many of them are NDEF formated.

The official NXP NFC tag -- NTAG213 I just ordered are still on the way. How about create a list collecting all tags workable with iOS? Thank you.

(sorry for not-directly-related issue!)
I couldn't find any resources online whether it is possible to use iPhone's RFID write capability (e.g. the capability that is used in apple pay)

anyone know if it is possible?

When i try to detect this(lb-m5215-1) RFID Tag it not detecting and throws an error as
"Required entitlement is missing"

Looks like RFID now is missing an unknown entitlement key in beta 3
Error reading RFID-Tag: Required entitlement is missing

Thanks for great example. But I have a question. ISO15693 API is private Apple API or it's just not presented yet?

Hi,

I only have a free developer account and can't get this project to compile. I always get errors about missing capabilities and entitlements.

The matrix here does not includes NFC (yet) :

https://developer.apple.com/library/content/documentation/IDEs/Conceptual/AppDistributionGuide/SupportedCapabilities/SupportedCapabilities.html#//apple_ref/doc/uid/TP40012582-CH38-SW1

As far as I know provisioning profiles can't be be managed from the developer portal with a free account, is that correct ? From what I understand it's managed automatically by Xcode.

Thanks

Ludovic

Feel free to check out https://github.com/jvk75/NFCNDEFParse
Small library that parses the NDEF messages ("well known types" as defined in NDEF specification) to usable objects. E.g. text type both locale and the payload string are in separate variable.

Early stage but usable. SP type coming soon...

These instructions mention a beta version of ti.nfc for ios, however the link provided does not seem to include the ios module. I apologize if this is the wrong place, but the projects appear to be related. Is the ti.nfc fork here the same beta version mentioned, or is there a better place to find this module?: https://github.com/hansemannn/ti.nfc/tree/2d14f18cf8898963a20eb809b968019cd16edee2/ios

Following similar instructions as iOS11-NFC-Example (using Entitlements.plist with the options mentioned), I've successfully built the module and the example Titanium app, but have run into some trouble and am looking for someplace to find some help. Thanks!

After the first NFC scan I get this error on the console when I try to scan a new tag agarin:

"Session is invalidated by user cancellation"

I believe it is because I have clicked on done or cancel before, is there a way to prevent that?

Crash App when Some NFC like print.

I don't have an Apple developer account, so I can't compile.

could it be that you need the decryption keys in order to even read the tag? For example, on US passports, the keys are derived from the passport data - name, birth date, etc.

I see in this Android NFC blog (see step 3) that they weren't able to read the data without possession of the keys: https://randomoracle.wordpress.com/2012/08/27/reading-the-us-passport-using-an-android-phone-overview/

I'm developing an application in which I want to get the NFC serial number and Identifier of a NFC tag. When I press a button, I want the application to find the UID and serial number of the NFC card. The only problem is that I have no idea how to get the UID and and serial number if that's possible on iOS. I m trying to get NFC identifier but i don't know how to get serial number of NFC Tag.

class ScanNFCTag: NFCTagReaderSessionDelegate {

import CoreNFC

var session: NFCTagReaderSession?

func scanNFCTag(sender: UIButton!) {
     self.session = NFCTagReaderSession(pollingOption: .iso14443, delegate: self)
     self.session?.alertMessage = "Hold Your Phone Near the NFC Tag"
     self.session?.begin()
}

func tagReaderSessionDidBecomeActive(_ session: NFCTagReaderSession) {
    print("Session Begin!")
}

func tagReaderSession(_ session: NFCTagReaderSession, didInvalidateWithError error: Error) {
    print(error.localizedDescription)
}

func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) {
    if tags.count > 1{
        session.alertMessage = "More Than One Tag Detected, Please try again"
        session.invalidate()
    }
    
    let tag = tags.first!
    session.connect(to: tag) { (error) in
        if nil != error{
            session.invalidate(errorMessage: error?.localizedDescription ?? "")
        }
        if case let .miFare(sTag) = tag{
            let UID = sTag.identifier.map{ String(format:"%.2hhx", $0)}.joined()
            session.alertMessage = "Successfully linked tag to location"
            session.invalidate()
            DispatchQueue.main.async {
                print("NFC Identifer = ", "\(UID)")
               }
           }
       }
   }
}

So, Here is the my code please let me know if i m doing wrong please correct me. Can someone please explain to me how to get serial number and UID of NFC tag,

Any help would be greatly appreciated.

Thanks in advance.

Hi, just wondering: Could you ever read any tag with your phone? I tried both your example and the one from Apple.
One tag on many that I have shows a "Produkt Erkannt" message, but then it doesn't actually read anything. All other tags time out when reading.
It's apparently very, very beta at this time, but I am wondering if you had more success.

Update: Even when the message "Produkt Erkannt" is shown, the "didDetectNDEFs" method is not being called. A few seconds after the message is shown, I am getting the "readerSessionInvalidationErrorUserCanceled".

Hey guys , I was trying to run this code but getting some errors.
Please find the attached SS

Hi hansemannn,
Thx for your code sample for NFC.
I have tried to use it, but I 've got an error with UITableView.
Please, your help is welcome.
Normally, NFC is working fine with my setup (tried with another basic application, and it works fine).

Here below, log error message...

Hi I have a PN532 NFCNDEFTag chip connected to an Arduino Uno, the chip should send a ndef message to the phone, everything works good in Android while this app seems not to see the chip.
The app works with a card but not with the chip?
Do you know why?

I need credit card information. Can I get it if it is suitable for contactless payment (NFC)? -> if okey, What do I need to get Credit Card Information?

Always prompt "The NFC-session is not ready so far, try again!"
