Paypal registration does not require a credit card, just a free email to apply.
If you authenticate by credit card, you will have the following benefits:
1. You can cancel the restrictions on PayPal payment and withdrawal.
After PayPal is registered, if there is no credit card or bank card authentication of China Merchants Bank/ICBC/China Construction Bank, you can only pay and withdraw up to $500.
You can shop directly on the website through PayPal.
PayPal accounts that have passed the credit card authentication can still shop through websites that support PayPal payment. Even if the PayPal balance is 0, you can pay directly through the credit card bound to the PayPal account.
