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?

Dear Community / Apple, I would like to ask in the name of many Smart Home Community, There is any developing / There is any future plan about make Apple Watches able to read NFC Tags / Stickers? Many of us would like to use Apple Watch to use Home Automations with NFC Stickers, but we have to use our iPhone instead of the Watch, what would be the most logical way to use these things. We does not really understand why this was not added by default, and why we cannot find any official information about this? Please provide us some answer, at least we should know should we still wait for this feature or this is not gonna be enabled by Apple?! Thank you very much, Gery

G'day. At my office the doors are locked with an NFC reader. We carry around a little NFC tag on our key chains which will read out a number and this then will open the door if the number matches a number in the database. I am tired of carrying around the tag, people keep loosing it, forgetting it and it would be nice to open the door using a Phone - which we tend to always have on us. So I used a credit card which is NFC enabled to readout the NFC information, added this number to the database and can now open doors using my credit card. This is pretty cool. If I forget my keys (most likely they will be on the desk but silly me left the desk without them), I may have my wallet with me. Then I tried Wallet.app on my iPhone and select the same credit card. However the door doesn't open. When looking in the door software I noticed that the tags will always transmit the same number. So does my credit card. However Wallet.app will read out 4 readings (or maybe just one very long one) and they are always different. So I can not make them match with the door database. Any ideas how to make this work? Can I give somehow wallet.app an NFC number which I can then add to my door database? Or how come the credit card and the very same one in wallet.app don't match? Thanks for your help! Would be neat if I could make this work out. This will make a lot of people happy at my office! Cheers!

I'm very excited about the new AirTag product and am wondering if there will be any new APIs introduced in iOS 14.5+ to allow developers to build apps around them outside the context of the Find My network? The contexts in which I am most excited about using AirTags are: Gaming Health / Fitness-focused apps Accessibility features Musical and other creative interactions within apps I haven't been able to find any mention of APIs. Thanks in advance for any information that is shared here. Alexander

Why is there no public APIs for developers (PassKit) to implement Apple Wallet NFC for employee badges as announced in WWDC 2021 Keynote? Can a simple Apple platforms developer implement this for the organization they are working on and don't have to go to third-party providers which seem to have this capability? Seems that I need to reach out to the below companies to enable this in the current organization I'm working with: third party providers: https://swiftconnect.io/owners/ https://www.hidglobal.com/solutions/access-control/hid-mobile-access-solutions

Hello everyone, I purchased a level lock touch earlier this year. It’s a lock I have on my front door and side door. One of the ways it can be unlocked is with an NFC card. You can tap the card and the lock opens. Since the apple devices have NFC, and so does the level lock touch, I figured there must be a way to just unlock the door by tapping my devices. I asked apple about this and they said they couldn’t help me. I reached out to Level and they said apple will be selling a new level lock + which on October 21st which does exactly what I’m wanting to do….for $329! my question is, if both devices have NFC- couldn’t there just be some type of software update to allow this feature to happen. Instead- someone has to purchase a whole new lock!? I know it’s all about money but it just doesn’t make sense to me. does anyone maybe know of a third party app that can read the level lock nfc card and allow me to open the lock by tapping my device? In the mean time I’ll keep looking for another way besides shelling out another 329 for a lock. Smh

Hi everyone, I work in a company with NFC-enabled reader manufacture. As for the title, I have searched for it for a lone time. Not NFC Certificate Request, it's for issuing passes. I inquired about MFI and the reply was that NFC is not within the scope of MFI. I have asked the local Apple team for help and they have no contact information for other teams and it is not clear which team to contact. My questions are below. Where is the correct and official contact window for Apple VAS? Is my post posted in the correct forum? If not, can you provide the correct place to ask? If possible, I hope to know the conditions for obtaining VAS authorization. Thanks a lot. Ken.

Hi, I'm developing an app that reads the NFC tags. So far so good, everything worked as expected, the app reads the passports and the IDs, until we encountered the french ID issued after March 2021. My app has the following entitlements: <dict> <key>com.apple.developer.nfc.readersession.formats</key> <array> <string>TAG</string> </array> </dict> And this additional entries in the .plist: <key>NFCReaderUsageDescription</key> <string>NFC usage to scan ID chip</string> ... <key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key> <array> <string>A0000002471001</string> <string>A0000002472001</string> <string>00000000000000</string> </array> According to an article which I cannot link on this forum because the domain is not permitted, iOS started supporting this specific ID from version 16. When I look at the docs, I can see the .pace polling mode was added. I tried specifying this additional polling mode in my app like so: var pollingOptions: NFCTagReaderSession.PollingOption = [.iso14443] if #available(iOS 16, *) { pollingOptions.insert(.pace) } self.session = NFCTagReaderSession(pollingOption: pollingOptions, delegate: self, queue: nil) But when I try to start the session it gets instantly invalidated with this message: Missing required entitlement. I'm pretty confident the message is misleading and something else is missing somewhere, my bet would be on the .plist entry com.apple.developer.nfc.readersession.iso7816.select-identifiers missing one of the cryptic numbers, but I have no idea where this can be taken from. How do I implement this .pace polling mode, can someone give me some guidance?

Hi there, I am using Core NFC and I established the connection with the card, (it means that the info.plist is correct and the entitlement should be correct as well). The app detects the card, but after sending the command 'tag.sendCommand()' I receive this message: [CoreNFC] -[NFCTagReaderSession transceive:tagUpdate:error:]:879 Error Domain=NFCError Code=2 "Missing required entitlement" UserInfo={NSLocalizedDescription=Missing required entitlement} So, what is missing or what am I doing wrong? Here is the code: func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) { guard !tags.isEmpty else { return } let hexString = //... if case let .iso7816(tag) = tags[0] { session.connect(to: tags[0]) { error in if let error = error { print("Error: \(error.localizedDescription)") return } let apdu = hexString.convertToAPDU() tag.sendCommand(apdu: apdu) { (response: Data, sw1: UInt8, sw2: UInt8, error: Error?) in // -> here is when the error appears, in the completion print([UInt8](response)) // print -> [] } } } }

I am developing an iOS app in which the device(iPhone) needs to act as an NFC tag using Felica so that an NFC reader could read the information present in this virtual tag (like person details). Currently Suica and Pasmo is being used for contact less payment but we ant to use the same technique but for our IOS app. Is it possible to achieve this ?

I am implementing the NFC feature from the iOS side and wanted to know that can we read the data from mentioned technologies here NfcA, MifareClassic, and NdefFormatable. can we implement NFC using core NFC that can read the data from MifareClassic tags?

I am implementing iOS APP with to read NFC tag with these mentioned technologies NfcA, MifareClassic, NdefFormatable so is there a way that I can access these types of tags. Can I access MifareClassic tags with iOS using coreNFC ?

Hello! Thank you very much for your WWDC NFC sessions! I really like the format and the information you provided in those session :) I have a question regarding my app that I am planning to develop using an NFC technology. I tried to find a necessary information in WWDC sessions and documentations but I couldn't find anything that might be helpful for me. The idea is simple. I want to use my app as the proxy between user's payments cards (debit or credit) and the payment terminal. The logic is something like this: User taps an iPhone to a payment terminal (just like in the Wallet) and my app reads the data from the payment terminal through NFC (merchant name, merchant category, amount to be paid, etc.) My app receives this information, does some formatting and other operations My app sends the user's card information to the NFC (a card information is received and stored in my app through some 3rd party service, like Plaid) Payment terminal receives this information and shows either the payment succeed or failed. I am wondering is it possible to achieve this using the current API of NFC framework? While I am aware that the NFC framework supports the ISO-7816 standard, based on my research so far, it seems there is no way to achieve this functionality. Correct me if I am wrong. Thanks!

Hey, I don't know why i can not make scan function work. I have written in the entitlement file: <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.developer.nfc.readersession.formats</key> <array> <string>NDEF</string> <string>TAG</string> </array> </dict> </plist> also in the info.plist: <key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key> <array> <string>A0000002471001</string> <string>D2760000850101</string> <!-- Add more AIDs as needed --> </array> still get the error Error Domain=NFCError Code=2 "Missing required entitlement" of course when i remove the iso18092 enum everything is working. Help? thanks

IPhone 14 Pro - ios 17 Beta NFC tag reader no longer functioning as of ios15 update. I have updated to Beta 17 and still not working. Airfrop off, cellular data off and have completed several restarts. Any help with repairing is appreciated. Thank you.

I want to read EMV protocol its possible today with IOS 16 ? its possible to use SELECT or others commands in APDU CoreNFC ? Its possible to interact with 2PAY.SYS.DDF01 ?

my app store application have met this problem most at OS version 16.6 and other OS version when i use [NFCReaderSession featureAvailable:],and Near Field Communication capability is equiped。I have no idea why this would happen。

We have to create CCC based digital keys so we are going to use UWB, NFC technologies. So Is there any CCC based UWB,NFC api available for development? We are members of the CCC organization. Could you please support us for this I have gone through UWB NFC document from official apple website.But I want to get idea on CCC based NFC and UWBs.

I am aware of NFC and UWB api which I have already gone through the official document page. We have to create CCC based digital keys so we are going to use UWB, NFC technologies.
