从付款的交易上看,Apple pay 比 Google pay 更安全。这篇文章说,用Google pay 付款时先通过Google 的服务器 (云端)然后再到卖方。也就是说在这个交易过程中,Google Pay 是做为中介的。
Google Security
With both systems, you provide your card details only once, during the initial setup. Google adopts an intermediary role and saves your card details on its servers. Google would then issue a virtual card to your device, the Google Pay virtual card.
When the seller charged the virtual card, Google, in turn, charged your stored
debit or credit card and is the only entity that ever sees your real card through this transaction.
Apple Security
Apple employs a different system known as tokenization. Here, when your card details are provided to the device, it contacts the issuing bank directly and, upon confirmation, receives a device- and card-specific token called the Device Account Number (DAN), which is stored on a secure chip on the device. The DAN structurally resembles a credit card number and is passed on to the merchant when any payment is made before getting authorized by the bank.
