## 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.

We have finished the last app of this course. Let's do a quick recap of what we learned during this journey.

We first discuss the differences between NDEF, NFC Tag Platform, and the tag-specific proprietary operations.

During the process of developing our NFC pokemon app, we focus on the NFC Type 2 Tag Platform.

The Type 2 NFC Tags describe their internal memory in blocks or pages. Each block or page has four bytes. The first four blocks for any given NFC tag contain several important data such as unique identifier or UID, CC block to describe the NDEF capability, and the tag memory size.

Type 2 NFC Tags also provide some general-purpose commands such as read and write operations.

The read operation starts with 0x30, followed by the starting block index, and the tag will send four blocks or sixteen bytes of data as the response.

The write operation starts with 0xa2, followed by the block index you want to write, followed by four bytes of data. The tag will respond 0xa when the operation success.

Congratulations!

We have finished the last app of this course. Let's do a quick recap of what we learned during this journey.

In this module, we go beyond NDEF.

We first discuss the differences between NDEF, NFC Tag Platform, and the tag-specific proprietary operations.

During the process of developing our NFC pokemon app, we focus on the NFC Type 2 Tag Platform.

## The Type 2 Tag Platform

The Type 2 NFC Tags describe their internal memory in blocks or pages. Each block or page has four bytes. The first four blocks for any given NFC tag contain several important data such as unique identifier or UID, CC block to describe the NDEF capability, and the tag memory size.

Type 2 NFC Tags also provide some general-purpose commands such as read and write operations.

The read operation starts with 0x30, followed by the starting block index, and the tag will send four blocks or sixteen bytes of data as the response.

The write operation starts with 0xa2, followed by the block index you want to write, followed by four bytes of data. The tag will respond 0xa when the operation success.

is there the code for the final UI of the pokemon app?
