Two methods: 1. You can use an international credit card and a domestic bank card (China Merchants Bank/ICBC/CCB) to authenticate two accounts respectively. For example, you use a bank card to verify your personal account and an international credit card to verify your premium account. 2. Authenticate two PayPal accounts with different bank cards. For example, you use China Merchants Bank card to authenticate personal accounts and China Construction Bank card to authenticate advanced accounts.

In addition to credit cards, PayPal authentication has added three bank card authentication methods: China Merchants Bank, ICBC and China Construction Bank. The purpose of certification is to cancel the restrictions on payment and withdrawal, facilitate the exchange of funds and improve credit. But each bank card (or credit card) can only be used to authenticate one PayPal account. That is, if you use the same domestic bank card to authenticate a premium account, you can no longer use this card to authenticate your personal account, and you will be prompted that this bank card has been authenticated in other accounts.
