How does Apple Pay work? Everything you need to know
Since its launch in 2015, Apple Pay has become one of the most popular payment methods among Apple users. But how does Apple Pay work, and what are the key technologies behind it? This article explores the technical advancements that power Apple Pay and offers tips on how to make the most out of this convenient payment system.
How does Apple Pay work?
At its core, Apple Pay is a digital wallet available on Apple devices like the iPhone and Apple Watch, allowing users to store their credit and debit cards securely. It utilizes contactless technology, encryption and biometric security measures to facilitate secure, seamless payments.
With Apple Pay, users are enabled to make payments for goods and services with just a tap of their smart device, offering a seamless and convenient payment experience. Here’s how Apple Pay works.
Add your card to Apple Pay
There are two ways in which you can add your credit or debit cards to the Apple Pay system. First, you can try by positioning your card in the on-screen frame. Your iPhone will scan the number and other details on the face of the card.
If you are having trough with the image capture function, you can choose to enter card manually with information such as card number, expiration date, security code.
Make payment with Apple Pay
To make in-store payments, simply hold your iPhone or Apple Watch near a contactless, NFC-enabled terminal. You’ll then authenticate the transaction using Face ID, Touch ID, or your device's passcode to verify your identity.
Apple Pay uses the stored Device Account Number (DAN) and generates a unique dynamic security code for each transaction, ensuring that your actual card details are never shared with the merchant, keeping your information safe.
For online and in-app payments, select Apple Pay as the payment method on supported websites or apps, then authenticate your purchase using Face ID, Touch ID, or your passcode. Payment details are securely transmitted with the same high level of encryption and tokenization as in-store transactions, keeping your card information protected.

Key technologies behind Apple Pay
Apple Pay is powered by a combination of advanced technologies that ensure security, privacy, and ease of use. Here are some of the key technologies utilized in Apple Pay.
Near Field Communication (NFC)
NFC is the key technology for fast, contactless payments without needing to physically insert a card. Thanks to NFC, you can make purchase or payments between your iPhone, Apple Watch or other Apple devices and payment terminals.
When you hold your device near a terminal, NFC initiates a secure connection to transfer encrypted payment information. Payments now only take about seconds to be fulfilled, saving a lot of time for both buyers and sellers.
Secure Element (SE)
The Secure Element (SE) is a dedicated chip designed to securely store sensitive information, including payment card details, biometric data (such as Face ID and Touch ID), and secure keys. By safeguarding this information, the SE ensures that it remains inaccessible to unauthorized users and applications. In an era where fraudulent activities are increasingly prevalent, such security measures are essential for protecting Apple Pay users.
The SE also facilitates the tokenization of your actual card number, ensuring that your real card details are never shared during transactions. Furthermore, it operates independently of the main processor of the device, creating a secure enclave that is resistant to tampering and malware. Together, these features significantly enhance the overall security of Apple Pay.

Touch ID / Face ID and Two-Factor Authentication
Touch ID and Face ID provide biometric authentication for Apple Pay, ensuring only authorized users can make payments. Additionally, Apple Pay uses two-factor authentication (2FA), adding an extra layer of security by requiring both your biometric data and a device passcode or verification via another trusted device. This combination ensures highly secure transactions.
EMV Payment Standard
EMV, which stands for Europay, Mastercard, and Visa, is an international standard for smart payment cards and terminals that authenticate transactions.
By utilizing EMV standards, Apple Pay significantly reduces the likelihood of card-present fraud. The use of dynamic codes and the secure storage of card information ensure that your actual card details remain safe, even if a payment terminal is compromised.
Moreover, EMV is widely adopted across, allowing Apple Pay to be compatible with a large network of merchants and payment terminals. This enables users to conduct secure transactions both domestically and internationally.
