Карта Билайн is a finance application developed by ПАО ВымпелКом that allows users to manage their finances easily. This Android app is exclusively for owners of payment cards issued by the company. With Карта Билайн, users can easily top-up their mobile phone, pay for various services, and even send money transfers.

One of the main features of the app is the ability to pay off any loans from any Russian bank. Additionally, the app allows users to send free money transfers to other Карта Билайн cardholders. Users can also view their account balance, transaction history, and create payment templates.

The app requires access to various device resources such as contacts, network connections, and camera/microphone. This is necessary for the app to function properly, including the ability to scan the card barcode for quick input of the card number.
