nfc

First of all I'm trying to read all the memory data from NCF Iso15693 Tag (icode slix2) I trying to call the method readMultipleBlocksWithRequestFlags of NFCISO15693Tag class. I'm reading the NFC tag and all the data seems to be correct(indeed in Android works perfect). I read the NFC tag in NFCTools app (https://apps.apple.com/es/app/nfc-tools/id1252962749) and I get all the data that I want to read. I using NFCTagReaderSession [[NFCTagReaderSession alloc]initWithPollingOption:NFCPollingISO15693 delegate:self queue:nil] the delegate code: id currentTag = [tags firstObject]; if (currentTag.type == NFCTagTypeISO15693) { id mytag = [currentTag asNFCISO15693Tag]; [tagSession connectToTag:currentTag completionHandler:^(NSError * _Nullable error) { BOOL available = [currentTag isAvailable]; NFCISO15693RequestFlag requestFlag = NFCISO15693RequestFlagAddress; [mytag readMultipleBlocksWithRequestFlags:requestFlag blockRange:NSMakeRange(0, 8) completionHandler:^(NSArray * _Nonnull dataBlocks

Hi, I am trying to put a MiFare DESFire v1 card on my apple wallet using my app. I can read the data and I think that the PkTransitPass should work. But I am really struggling to see how you make a pass with this. Do I need an Nfc certificate? Any help is much appreciated

I would like to create an app that turns my iphone into a nfc tag, is this possible

Hi , App Clip is great for user to scan NFC Tags . But I found that , when user first scan the NFC Tags with associated URL in it , the app clip receive the userActivity is empty. not only for NFC Tags , also appear on QR Code. Another things, when you scan the NFC Tags with URL in it , which associated the app. The App Clip card appear. but cannot receive any ndefMessagePayload in userActivity (only for NFC Tags). Before App Clip appear, in iOS 13 & iOS 12. when you scan the NFC Tags with URL in it , which associated the app. you can receive ndefMessagePayload in userActivity.

We've developed an app which performs data transfer with a control board over NFC. The NFC tag we're using is a type 2 NXP Ntag with 2k memory. The app works fine with models up to iPhone 11. However with iPhone 12 onwards, we've been experiencing constant NFC tag detection or NFC session termination failures. Moreover, when it fails one time, it keeps on failing for next consecutive attempts no matter how I hold the phone next to the NFC chip. I've tried all distances from 0cm to 4cm and all directions, nothing works. I'm confident that nothing's wrong in the NFC implementation since the same app works absolutely fine on other iPhone models with iOS versions ranging from 14.6 to 15. Is it something related to sensitivity of NFC transceiver? Is there any way it can be compensated at the source code?

Hello, my name is Antony Basta and I am the developer of an app called SecuriKey. SecuriKey allows any old apartment building intercom to be controlled from an app. Users can create entry codes that work once, up to a certain date, or are instantly revokable. There is no need for any new or additional hardware – it works with the buildings existing intercom. Currently, the app is using Stripe for subscriptions and it was initially approved 2 months ago for the App Store. I pushed an update a few weeks ago and Apple Rejected it because I am not using In-App Purchase (IAP). I submit an appeal, mentioning that we offer a consumable service that takes place outside of the app (guideline 3.1.3(e)), it is effectively a Reader app since we provide VoIP numbers to our customers (guideline 3.1.3(f)), and SecuriKey requires hardware to function – that is, it will not work without a physical intercom (guideline 3.1.4). Additionally, we do ship physical goods to our customers (NFC tags and Security Signs) monthl

Hi! We have two apps, both use the Universal Links mechanism, apps should be opened when user read NFC tag. The tag content is a URL link to our domain. After updating to iOS 15, users faced the problem that they constantly see the application selection dialog when reading the nfc tag. How to fix it? Previously, the selection dialog was displayed once and the value was stored. Our aasa file on domain: { applinks: { apps: [], details: [ { appIDs: [*.*.app1], paths: [*] }, { appIDs: [*.*.app2], paths: [*] } ] }, appclips: { apps: [ *.*.app2.Clip ] } }

Hi, So I'm developing an app that actively uses NFC. Anyways, we use NFC tags that have a firebase dynamic link, that basically primarily opens the link in-app as a universal link, but if the app isn't installed, its really just a web link that opens in Safari. So the user flow should really just be the iPhones detecting the NFC tags, showing the notification for the NFC detection to open the link in the app or Safari, and so on. The issue is that, consistently about half the time, scanning the NFC tags opens Apple Wallet/Pay, even prompting Face ID. Although even if Face ID is successful, no transaction actually occurs. But that's the thing, see the NFC tags are really just embedded with simple web links as NDEF, nothing to do with Apple Wallet or Pay whatsoever. I'm not sure if it's just supposed to be the default action on iOS to open Apple Wallet when NFC is detected, but anybody know a workaround for this? (I doubt configuring with support fo

Has anyone managed to emulate a RFID / NFC tag with the iPhone? Either with Apple Pass / Pay, or CoreNFC? If so, how? We are looking at the MiFare standards, but any NFC emulation (like HCE for Android https://developer.android.com/guide/topics/connectivity/nfc/hce#ManifestDeclaration )

Hi everybody. I have a question about NDEF Messages. I just begin to learn CoreNFC from tutorials and Apple documentation. I'm trying to do an app with a Form and I want to write those TextFields into a NFC Tag . The tag that I'm using is a NTAG 125 wich works perfectly with IOS, but this is my problems I don't understand very well how payload works. Is possible to write a dictionary in the Tag ? or I'm forced to write each record at the time? For example: I want to write this in my Tag username: Rafael lastname : Castro Id: 0701334445 loginDate: 2021-11-02 Since I may be updating the Tag from time to time if instead of one register, the ones wrote down in my tag are 4 I thing I will be depleting the tag memory very quickly. Someone can help me with this ? Thanks in advance !

I want to read the UID from the tags that I have but i Don't know what to do. I'm using a NTAG125 tags
