I decided to try the merchant acquiring service from T-Bank because there was a promotion with a low commission. I submitted an application, and half an hour later, the manager Yuri called me back. He explained the terms in detail, and I realized that the 3-in-1 cash register would be the best option for me since it is multifunctional. I confirmed the application, and three days later, a technician came to me. He updated the labeling, installed the SIM card, and checked the Wi-Fi connection. The 3-in-1 cash register responds quickly to commands, and I can send receipts according to the 54-FZ law. And the best part is that I don’t have to pay anything for the rental to T-Bank.
