One-click login and checkout via Apple Pay


Watch a video

One Click Apple Pay Checkout eliminates almost all friction for customers willing to buy crypto as seamlessly as possible using Apple Pay. Customers will not be required to enter the email or any other customer or payment data.

After initiating the purchase via Paybis Onramp customers are instantly directed to the payment page where they can finish the payment in 1 click. This functionality is particularly useful for non-custodial solutions but can become a killer feature for any other partner out there.

*customer verification from a certain amount spent can be applied
