Digital bank credit card is actually an "electronic credit card" and a virtual card. After the customer successfully applies, the bank will provide a set of virtual card number, security code, expiration date and other information. After the customer is activated, it will be bound to the issuing bank's mobile banking, or UnionPay China UnionPay Express, as well as third-party payment platforms such as Alipay and WeChat, so that payment can be made quickly. There is no problem with online and offline consumption of digital credit cards. When paying online, check the digital credit card number and enter the payment password to complete the payment. When spending offline, you can scan the code through mobile banking, UnionPay China UnionPay Express, or bind APPLEPAYHUAWEIPAY for mobile phone flash payment. Every bank provides digital credit cards, some of which are dual-card attributes, with both virtual card numbers and physical cards.
