Sberbank told the first details about installing proprietary software on the iPhone. We are talking about the SBOL application, and the Sberbank Installer iOS utility is used to install it. You can install the program only at a bank branch, while the user will have to unlock the phone and hand it over to an employee.
In addition, there is a web version of Sberbank Online, which is available through a browser. This version is updated regularly.
Technically, the new Sberbank utility is based on iMazing, software that allows you to install programs from a PC to a smartphone. At the same time, Apple probably knows how it works. So do not rule out the possibility that iMazing and other utilities of this kind may turn off when they want it in Cupertino. But for now, they are working properly.
Recall that before the New Year reported on the return of the Sberbank branded application to iOS.
