Introduction

This is a experimental project about Android NFC functionality. The whole idea is based on using android device as a Host Card Emulation, however we cannot simply send a byte array by realising communication enter iOS and Android because of iOS can only accept NDEF Message. So I'm enlightened by reading NFCForum-TS-Type-4-Tag which simulate the whole process command talking cross devices. You can find more details by reading this documentation. You can find iOS Reader Tag Project in my repo

Architecture

The whole project conclude 3 projects modules globally.

| Module | Status | |:--------------|:-----------:| | app | Android Host Card Emulation of a NFC Forum Type-4 tag | | readNfcMessage | NFC Read Application to verify HCE Android Completion | | nfcemvread | NFC Read Application to get Card Bank Information |
