CCC based UWB NFC API
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. 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.

Unique TagID and NFC Core
Will NFC Core give access to the unique tag ID of NFC (ISO14443) and ISO15693 tags? For example, the standard format for ISO15693 tagIDs is a 64-bit unique identifier (ie 16 hex characters starting with E0). This is very necessary for many use cases.

Interact with NFC Reader ISO7816
Hi, we’re developing an app that needs to interact with a NFC Card Reader using ISO7816 protocol; even with iOS 13, it seems we can’t do it, neither in HCE nor in another way. Can you confirm that? There are other ways to communicate with a NFC Reader using NFCCore?MB

iPhone NFC reading on different generations
From what I know, the iPhone can read NFC tags since 2017 (Core NFC) only on the iPhone 7, 7 Plus, and later. I also know that iPhone XR and later can read tags in the background. My question is the following : what is the difference between reading an NFC and being able to use the phone to scan a NFC ? Technically, paying with Apple Pay on an iPhone 6s, being the first to support Apple Pay is possible, but why is that phone model unable to read NFCS ? Thanks for the answers.

NFC Tag emulation inside the application
Hi, I know, there are the same questions on forum posted before, just it looks like they become old and almost of them are left without answers. We need to develop the application, which can use NFC inside and emulate the NFC Tag. Our embedded device contains the NFC reader and sends the NDEF messages with custom dynamic payload and it is expected that the answers will contain also custom payload depending on the request. Simply, we need to implement data exchange using NFC NDEF messages. We examined the Core NFC framework - it allows only using the iPhone as NFC reader. Looks like not suitable for us. Then we checked the Pass.NFC framework and, if we understand all correctly, it allows to create the NFC card/pass in the wallet with fixed payload, also looks not suitable for us. There is the application NFC Tools Pro in the App Store and it allows to emulate the NFC Card inside, there is the demo video how it works. Here is the l

NFC Tag for Calculator App
Hi there, I'm brand new to the world of NFC, and have a bit of a niche request. I'm looking for a way to program an NFC tag to launch the Calculator ios app and preset it with a string of numbers. I'm a mathematics teacher and wanted to use this to secretly insert a string of numbers into a calculator as a math magic trick to demonstrate order of operations. If that's impossible, would an NFC tag be able to copy text to an iOS clipboard automatically, which I could then long press to paste into the calculator?

NFC Host Card Emulation support
Hi, I am developing an iOS app in which the device(iPhone) needs to act as an NFC tag(conforming to ISO 14443) so that an NFC reader could read the information present in this virtual tag (like UID). How can I acheive this ? Does iOS supports NFC Host Card Emulation ?

NFC Security Key Support on MacOS
It's currently possible to use a security key (ex. Yubikey 5 NFC) with an iPhone via NFC, but such functionality is seemingly not possible on any current versions of MacOS. Is support for NFC hardware authenticators (over an NFC-to-USB interface/device, such as the ACS ACR122U) planned for MacOS Monterey or any future release?
