2. Once Paypal has been setup, now navigate to **Advanced** | **Payment Authorization**. You will see PayPal enabled. Click on Authorize. This will open a new window where you will enter your paypal credentials to login and that will authorize Point of Sale to accept payment on Paypal Reader for the merchant.
