In Detail

Apple Pay, one of the most spoken about offerings of the latest iOS 9 release, is a digital wallet and electronic payment system developed by Apple Inc. Paying in stores or within apps has never been easier or safer. Gone are the days of searching for your wallet, and the wasted moments finding the right card! Now you can use your credit cards and rewards cards with just a touch.

Apple Pay allows payment by Near Field Communication (NFC), or allows payment within an iOS app. Your card details are never shared when you use Apple Pay-in fact, they aren't stored on your device at all. How to implement Apple Pay in customized apps for payment is a bit tricky, but our book solves this problem for you.

Whether you are a brand new iOS app developer or a seasoned expert, this book arms you with necessary skills to successfully implement Apple Pay in your online-payment workflow.

We start off by teaching you how to obtain the certificates to encrypt customers' payment information. You will then learn to create payment requests and determine whether the customer can use Apple Pay. We will use Xcode and Objective C for the interface and Node.js for server side code.

You will get to grips with designing a payment-processor program to interact with the payment gateway. You will also find out how to customize your processor according to your preferences to implement a secure payment system. Finally, we take a look at a business-focused view of Apple Pay protocols and classes.

By the end of this book, you will be able to build a fully-functional Apple Pay integrated iOS app.
