Hello, a business that sells online needs to connect a system to receive payments on a website or mobile application. Safe acceptance of funds by transferring a payment from a card to a card or a company's current account by a client is provided by online services, such as payadmit, which provide an acquiring connection service. These are such modern solutions for e-commerce and mobile commerce that allow billing for services and goods not only on the website or in the application, but even without them - in social networks and instant messengers.
