How to Set Up Apple Pay Using Stripe For Your Shopping App

Apple took a big step into the world of mobile payments with the introduction of the iPhone 6 and Apple Pay. There are two ways you can use Apple Pay to purchase items: at the point of sale using Near Field Communication (NFC), or within an iOS app.

In our last article, we talked about how integrating mobile payment gateways can benefit for your shopping app and how Stripe is used by most popular startup apps like Uber, Instacart, Grab, Postmates, and more. However, we somehow missed to talk about how to set up Apple Pay with Stripe in your iOS app.

In this article, we’re going to fix this. Get your Xcode installed and running, and let’s learn how to set up Apple Pay using Stripe!

What is Apple Pay?

Apple Pay enables people to easily and securely pay using their iPhone, iPad, and Apple Watch. Apple Pay is available within native iOS applications, and on the web in Safari starting with iOS 10 or macOS Sierra.

How Does Apple Pay Work?

Apple Pay is quite similar to Paypal because in that you can integrate it in your app to allows users to pay for their purchased goods and/or services online. But, what makes Apple Pay different is that it uses NFC technology that lets users pay for products in physical stores equipped with NFC readers.

For you reference, here is the list of stores that accept Apple Pay.

Now, the Apple’s payment system is compatible with all existing readers like American Express and ExpressPay, Visa PayWave, but unlike Samsung pay, it does not work at standard payment terminals with magnetic stripe readers.

To pay using Apple Pay, first you’ll need to add your credit cards through Wallet app. Though, you don’t need to write the complete credit card number or expiry date as you can use your iPhone’s camera to read this information automatically.

Now, to make a transaction, all you need to do is select Apple Pay from the payment options list, choose your credit card, and hold your fingerprint on Touch ID to authorize the transaction.

How Does Apple Pay Store My Credit Card Details?

Simple answer is: It Doesn’t!

Instead, it assigns a unique Device Account Number for each device, and saves this number in the Secure Element Chip on the device in an encrypted format.

So, when it is processing any transaction, it doesn’t transmit the data on a bank card to seller. Here, it uses its dynamic safety code. By doing this, it ensures that nobody can reveal your credit card information using Apple device.

Also, since Apple Pay stores a secure transaction on device, you won’t need to have data connection for Apple Pay. What this means is, you can pay for products without your iPhone if you own an Apple Watch.

In fact, you might have also noticed that Apple Pay system is spreading quite fast, so make sure you can grab the users paying through Apple Pay, we’ll see how to set up Apple Pay using Stripe in your iOS app.

When Should I Use Apple Pay?

Many people keep getting confused as to when we should be using In App purchases and when to use Apple pay. The key difference is that any thing digital which you sell inside the app needs to be using In App purchases. If you are selling any physical products like tickets, uber, event tickets etc can use Apple pay.

Quick overview of how it works

  • User uses Touch ID to authorize transaction.
  • Your app receives the payment token.
