With SSL your online payment is secured. SSL (Secure Sockets Layer) is a standard security technology for establishing an encrypted link between a server and a client—typically a web server (website) and a browser; or a mail server and a mail client. SSL allows sensitive information such as credit card numbers, social security numbers, and login credentials to be transmitted securely.
Troubleshooting credit card payment errors
PayPal is the preferred payment method for most online buyers and sellers, and lets you send payments securely online using a credit card or bank account.
When you send a payment using PayPal, the recipient doesn't see your credit card or bank account information. Learn more about how eBay and PayPal work together.
Before you send a payment using PayPal:
Make sure that the seller accepts PayPal as a payment method.
Make sure that your PayPal email address is correct.
