苹果宣布Apple Pay支持Visa卡，安全吗

Group 1 - Apple Pay has opened the option to bind Visa cards, requiring users to rebind previously linked dual-branded cards, which can now be selected for either Visa or UnionPay [1][3] - Users can choose to use either Visa or UnionPay based on their needs, with Visa being usable only at merchants with Visa signage abroad, while UnionPay can be used both domestically and internationally [1][3] - The dual-branded card, a product of collaboration between UnionPay and foreign card organizations, was created to address the challenges of using UnionPay cards abroad and foreign cards domestically during a time when the Chinese card clearing market was not open [3][4] Group 2 - The dual-branded card is essentially two cards combined into one, utilizing the UnionPay network domestically and both Visa and UnionPay networks abroad, but new issuances of such cards have ceased as foreign card organizations can now obtain licenses in China [4] - The introduction of Apple Pay's binding feature for Visa cards has attracted many users with overseas spending needs, as the contactless payment method is seen as more convenient and secure, reducing the risk of card theft [4]
