The US is a leading iOS-strong market where iPhone share reaches roughly half of all smartphones, and in Safari and in-app environments the Apple Pay button replaces card number and shipping address entry with a single biometric authentication. Card details are stored as a device-specific token (device account number), so the actual card number is never exposed to the merchant or payment network — a structure that delivers both security and payment speed, which is why it has become established as a go-to method.

The effect is clear-cut for merchants concerned about mobile web checkout abandonment, especially in categories with a high share of mobile purchases such as fashion, beauty, and digital content. For a US-facing app service with a high share of iOS users, simply placing Apple Pay as the first option in the in-app checkout flow can deliver a noticeable conversion improvement.

When a consumer taps the Apple Pay button on Safari web or in an app, a payment sheet opens, and the device's tokenized card is approved via Face ID or Touch ID authentication. Shipping address and contact details are also passed through the sheet, eliminating manual entry steps, and the approved funds are collected by Hecto Financial in USD, then converted and paid out in the contracted currency. Tokenization itself acts as an online authentication mechanism that reduces the risk of card number exposure.

Through Hecto Financial integration, Korean merchants can also review Apple Pay acceptance on their US-facing web and app. Because there are online integration requirements such as Apple's domain verification, you need to confirm the applicable setup based on your own store's environment (web/app, browser configuration), and the detailed conditions are worked out through a consultation with the sales team.

• Business registration country

  Confirm whether a contract is available for merchants registered in Korea

• Sales channels

  The integration method and priority vary depending on your online sales channel mix, such as your own store, open marketplaces, or mobile apps

• Product categories

  Check in advance whether your products fall under categories restricted by Apple Pay's merchant policy

• Local regulatory compliance

  Confirm compliance with US payment and foreign exchange rules, including federal and state consumer protection and card network rules (see official sources below)

US transaction funds approved via Apple Pay are collected in USD, then converted and paid out to the merchant in whichever of USD, KRW, or JPY was chosen in the contract. Refunds are returned to the tokenized original card, so clearly stating in consumer messaging that 'the refund goes to the card originally used' can reduce inquiries. The payout cycle and fee terms follow what is specified in the contract.
