CoreNFC ISO7816 Tags

Hi Andy,

Thanks you for sharing.

Have you tried Hong Kong Passport?

Thank you.

My colleague and I ran both Apple's and AndyQ's examples on an iPhone XR but it won't read anything – we tried passports, ID cards and credit cards. We have enabled the NFC entitlement, added it in the app, added all the tags suggested above in the info.plist – but nothing changes, even though `readingAvailable` returns `true`. We are using Xcode 11 beta 2. Any clue what we are missing?

I see the same error with "Version 11.0 beta 2 (11M337n)"

Hey @Andy, same is happeing here with Xcode Version 11.0 beta 2 (11M337n)
and the MacOS 10.15 Beta (19A487m)

It wont happen if you check out using git. Only happened to me when downlaoding the zip and extracting it.

You are right...I already have that fix.
But now I am having the same issue as some other persons are talking I don't receive any call back even if using the iPhone XS

I ran AndyQ's example with ePassport (AID A0000002471001) and got an error on connect to tag:

Error Domain=NFCError Code=100 "Stack Error"

Error Domain=nfcd Code=28 "Tag Not Found"

iPhone X, iOS 13 beta 4, Xcode 11 beta 4

Anybody had luck reading a credit card? My app is not called back on an iPhone 7 with beta 4 - and I verified the aid in the info.plist is correct ( https://github.com/tengelmeier/cardbrowser-swift/ )

I thought the video presentation mentioned that known payment card AIDs would be ignored/banned?

*Sigh* Seem to have missed that in the Session video, and it's not in the docs.

Yes, I just verified. It's in the 2019 Core NFC Enhancements video at time point 9:00.

"However, for the time being, reading payment cards will not be supported."

Presumably they want to encourage Apple Pay as the only kind of payment handling the phone engages in.

I have problem, when I'm trying connect session to detected tag.

I use NFCTagReaderSession(pollingOption: .iso14443, delegate: self)

Xcode 11 beta 4 and iPhone XS Max iOS 13 beta 4, Xcode 11 beta 5 and iPhone XS Max iOS 13 beta 5

public func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) {
        
        Log.debug( "tagReaderSession:didDetect - \(tags[0])" )
        if tags.count > 1 {
            session.alertMessage = "More than 1 tags was found. Please present only 1 tag."
            return
        }
        
        let tag = tags.first!
        var passportTag: NFCISO7816Tag
        switch tags.first! {
        case let .iso7816(tag):
            passportTag = tag
        default:
            session.invalidate(errorMessage: "Tag not valid.")
            return
        }
     
        // Connect to tag
        session.connect(to: tag) { [unowned self] (error: Error?) in
            if error != nil {
               
                session.invalidate(errorMessage: "Connection error. Please try again.")
                return
            }

When delegate method detect tag and run session.connect(to: tag), I have such error

tagReaderSessionDidBecomeActive

tagReaderSession:didDetect - iso7816(<NFCISO7816Tag: 0x281124f30>)

2019-07-31 13:00:06.271219+0300 NFCPassportReaderApp[308:16921] [CoreNFC] 00000002 83148680 -[NFCTagReaderSession _connectTag:error:]:553 Error Domain=NFCError Code=100 "Stack Error" UserInfo={NSLocalizedDescription=Stack Error, NSUnderlyingError=0x281125e90 {Error Domain=nfcd Code=28 "Tag Not Found" UserInfo={NSLocalizedDescription=Tag Not Found}}}

Does anybody had such problem and know how to fix it?

Is there a list of AIDs supported by CoreNFC?

Hi Aleksandr, I have a similar issue with reading a smart card - returns code = 29 "Tag Error"

wait.. adding to PLIST or Entitlements?

I added to plist and seems to work, but docs state we must add to entitlements...
