Standalone

The PayPay Standalone terminal is an autonomous solution that allows you to accept card payments quickly and easily, without requiring complex technical integration.

Integration Architecture

The Standalone terminal operates autonomously with automatic synchronization with the PayPay backoffice. Optionally, it can integrate with external systems via webhooks.
