The Respondent platform is set up to make automatic payments via PayPal only.
If you don't have a PayPal account but would like to participate in studies, you can easily set up a PayPal account by following these steps: https://www.paypal.com/us/webapps/mpp/account-setup
Alternatively, you can set up a PayPal account after a payment has been made to you.
At the time a payment has been deposited into your PayPal account associated with your email address, you will be notified via email. At that stage, you can follow the prompts in the automated email to create an account to claim the money that has been deposited to you.
