## What we will cover in this course

First, I will provide an overview of NFC technology, so you can understand basic concepts and terms. After that, we will build three apps throughout this course.

### App 1: Tag Counter

App 1 is a game app to count how much time a user needs to scan five NFC tags. You will learn:
- how to properly set up an NFC project 
- how to trigger NFC scanning
- the difference from iOS and Android regarding NFC feature

### App 2: Tap-and-Go

App 2 is about NFC Data Exchange Format (NDEF), which is the standard NFC data format supported by both iOS and Android. NDEF can be used for almost any NFC tag. We will build an NDEF reader-writer app, and you will learn:
- how to write specific NDEF URI into NFC tags 
- how to read NDEF URI and trigger corresponding actions, for example, opening an URL, making a phone call, or sending a message. 
- how to use deep linking with NFC tags.

### App 3: NFC Pokemon

App 3 dives into low-level NFC programming, which directly manipulates the NFC tag’s internal memory and uses proprietary NFC commands. 
The app we'll build is called "NFC Pokemon," which is a digital identity management platform. It can seal a specific Pokemon, for example, a Pikachu, into an NFC tag. 

When building this app, you will learn:
- how to use low-leve tag command to directly manipulate NFC tag's internal memory
- how to create digital signatures in React Native
- how to use proprietary password protection command for NXP NTAG 213 / 215

NFC technology is everywhere in our daily life, from transportation, access control, to payment system. However, understanding NFC is still a hard topic because of its wide technology landspace. 

So in this course, We will guide you from the simplest case like using common NDEF format, all the way to a complex digital identity management app which leverages some unique NFC features.

In order to write NFC apps, our first step is to be able to scan or discover NFC tags. 

So in this module, we will build a game to count how much time a player needs to scan five NFC tags.

During the app building process, we will also learn some important concepts

First, how to properly configure your app, especially for iOS.

There are some pre-steps you will need to perform, otherwise your NFC apps will

Second, how to use React Native NFC Manager library to discover our NFC tags.

Third, since the NFC feature is not supported by all mobile devices, you will

the case when the target device has no NFC feature.

Finally, you will also learn how iOS and Android handle NFC events differently.

iOS has a default system UI and Android provides none of this.

How to produce a similar user experience is an important topic.
