PayPal is a secure online payment system for cash free transactions on the internet. If you have previously registered a PayPal account and added a payment method you can use this PayPal account for many different services and onlineshops. You can for example use PayPal to pay for your BookBeat subscription.
When you sign up for BookBeat you can choose PayPal as your payment method by accepting our terms and conditions and clicking on "Continue to PayPal". You will be forwarded to PayPal where you can choose to pay with one of your registered payment methods.
When you're done you will be forwarded back to BookBeat and your registration will be completed.
If you want to use PayPal as your payment method then please note that your PayPal account has to be verified. PayPal uses verfication to make sure that the chosen payment method is really yours. You can learn more about account verification here.
