With the rise of digital wallets and contactless transactions, Apple Pay in 2025 has solidified its place as a core component of the Apple ecosystem. From your iPhone to your MacBook, iPad, and even Apple Watch, Apple Pay now delivers a cohesive and secure payment experience across all devices.

And if you’re already part of the Apple wearable ecosystem, check out our Apple Watch SE 2 Ultimate Guide to understand how your wrist can become your wallet.

Let’s explore how Apple Pay works across every device, how to set it up, and how to get the most out of it.

Why Apple Pay Is No Longer Just Mobile

Initially launched as a tap-to-pay service for iPhones, Apple Pay has matured into a cross-device transaction platform supporting:

  • In-store NFC payments
  • In-app purchases
  • Online browser checkout (Safari)
  • Transit cards and passes
  • Contactless cashless rewards

In 2025, Apple Pay is:

  • Globally supported in 74 countries
  • Connected to over 6,500+ banks
  • Responsible for $3.8 trillion in secure digital payments annually

  2. Tap + Add
  3. Follow prompts to scan or enter card info
  4. Authenticate with Face ID or Passcode

Adding Apple Pay to Apple Watch (WatchOS 11)

Steps:

  1. Open the Watch app on your iPhone
  2. Tap Wallet & Apple Pay

Apple Pay on Mac (macOS 2025)

There are two Mac configurations:

Macs with Touch ID:

  • Go to System Settings > Wallet & Apple Pay
  • Add card directly
  • Use Touch ID to authorize browser or app purchases

Macs without Touch ID:

  • Enable “Allow Payments on Mac” from iPhone > Wallet & Apple Pay

Works flawlessly in:

  • Safari checkout
  • Apple subscriptions
  • Secure autofill in apps

Pro Tip: Use Face ID on iPhone to approve Mac transactions without typing.

Apple Pay on iPad

  • Navigate to Settings > Wallet & Apple Pay
  • Add a card manually or sync from iPhone
  • Authorize purchases via Face ID or Touch ID

Ideal for:

  • App Store purchases

Unified Features Across All Devices

Apple has enabled the following benefits through iCloud and Secure Enclave integration:

  • Card Sync Across Devices
  • Transaction History visible across platforms
  • Loyalty Integration on any device

Use Case – Small Business Owner Efficiency

Testimonial – Rachel, Boutique Owner

“I run payments from my iPhone in-store, approve supplier invoices from my Mac, and use my Apple Watch while traveling. I’ve eliminated all plastic cards—Apple Pay across my devices just works.”

Rachel’s setup:

  • iPhone + Apple Watch for in-person transactions
  • iPad for invoicing

Security & Privacy: Built-In, Not Added On

  • No card numbers stored on device
  • Every payment uses dynamic security code
  • Face ID / Touch ID / Passcode required per device
  • Secure Enclave ensures only authorized devices approve payments
  • Lost mode disables Apple Pay remotely via iCloud

Apple does not track your transactions or spending behavior.

FAQs

A: Yes. You can customize which cards appear on each device and assign a default per device.
