nfc

Hi everyone, I'm working on something that needs to be able to identify the identity of a merchant when the merchant starts an NFC transaction. Is there any suitable API that can do this? I'm not sure if this would be an Apple Wallet or an Apple Pay API. I don't want to settle the actual transaction, I just want to identify the merchant. Thanks for any advice in advance. 🙏🙇

Hi I’m hoping that someone can give me a definitive answer on this as if it is not possible then I will need to look at other possibles ways around it. I am developing an app that will need to check regularly whether an NFC tag is nearby but it won’t be convenient for the user to accept the notification every time, is there a method I can implement so the user can accept the permission to scan the NFC tag passively in the background without showing a notification?

I'm working on an NFC app for R&W operations on an NFC tag. All R&W operations work fine with the 'SendMiFareCommand()' API, however there's a special command for 'password authentication' feature where it fails with a timeout, may be because the NFC tag is not responding in time. This issue is not observed every time, so I'm sure about the command I'm sending nd how its response is to be processed. Moreover, this issue appears more frequently on iPhone 12 & 13 than older ones, may be because they changed something at the NFC lower layer. Anyway, Android allows adjusting timeout which is usually done before sending any command, so that it gets enough time to respond and the session remains active. It's typically done as - mifareTag.Timeout = timeout_value_ms; Can this be done for iOS? What is the default value of the timeout? If timeout cannot be modified, is there any alternative to allow enough time for the NFC chip to respond to the commands being se

My issue is that I have NFC functionality implemented but it does not work on iPads. I wanted to know if iPads supports NFC reading & writing.

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

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 !

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, 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

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 ] } }

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

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?
