In the context of Self-Assessment Questionnaire (SAQ) C-VT, a virtual payment terminal is web-browser-based access to an acquirer, processor, or third-party service provider website to authorize payment card transactions, where the merchant manually enters payment card data through a web browser. Unlike physical terminals, virtual payment terminals do not read data directly from a payment card. Because payment card transactions are entered manually, virtual payment terminals are typically used instead of physical terminals in merchant environments with low transaction volumes.
