1. Log in to paypal official website, register your personal account, and enter the domestic credit card number, expiration date and the last three digits of the reverse signature to associate the credit card. This step is simple. Please follow the instructions on the web page. Associate the switch with paypal later, and then set the exchange rate.

2. After receiving the email, click the first link and log in the account of the member you want to buy (if you can't log in, use the password modification method). After logging in, you will be asked to set the payment method, select the column marked paypal, and then bind the switch to paypal.

3. Next, go back to the payment page of switch and continue to choose paypal payment? Enter the password entry page, pay attention to the Nintendo password entered here, not the payment password, and then you can pay.
