Currently, the Apple Pay service can only be used on the iPhone 6, iPhone 6 Plus, and Apple Watch, and is only available in the United States. In fact, this Apple concocted payment method is a transaction service that will replace the old or conventional system, such as a debit or credit card. Apple Pay itself has various advantages that will make your shopping activities easier, such as speeding up payments and being confidential so it is very safe
Actually, Apple Pay is like a credit or debit card. It's just that, Apple made it easier, where it was conjured to replace a physical credit or debit card. And the virtual card on the iPhone is a debit or credit card from the user himself. To make it very easy, users simply sign in to their iTunes account. After that, users just need to take a photo of their credit or debit card using the iSight camera on the iPhone. After completion, the virtual card can also be used to make payments at various merchants that have NFC technology. The card data created earlier will be stored in one of Apple's exclusive services, namely Passbook. Don't worry, all card information stored in Passbook is intentionally not properly recorded on the iPhone or the server for security reasons.
