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 link to the video: https://www.youtube.com/watch?v=op3B9iIuMKg And it looks like we need exact that functionality. How can we implement this? Any suggestions, hints? Thank you for the help in advance.
