Preparing the device for installing banking software
Before starting any manipulations with the file system of your smartphone, you need to make sure that the operating system is ready to accept new software. Modern versions Android have built-in protection mechanisms that, by default, block the installation of applications from unknown sources. This is an important barrier cybersecuritythat needs to be temporarily bypassed in a legal way.
Go to the settings of your gadget and find the section responsible for security. Depending on the phone model and firmware version, the path may differ. Usually it looks like this: Settings → Security → Install unknown applications. Here you will need to grant permission to the specific browser or file manager through which you plan to run the installer.
⚠️ Attention: Never grant permission to install unknown applications to all apps at once. Grant access only to the file manager or browser that you are currently using to download the file.
It is also critical to check the availability of free space in the device memory. Banking applications, especially such functional ones as RNKB, can take up significant space after unpacking the cache and updates. It is recommended to have at least 500 MB of free memory for correct operation of the system during installation.
☑️ Ready smartphone for installation
Search and download the official installation file
The key step is to find the right source to download. The official RNKB application is distributed free of charge, and any attempt to monetize this process by third parties is a sign of fraud. The main and most reliable distribution channel is the store Google Play. If your device does not have Google services or access to the store is limited, you should use the official website of the credit institution.
When downloading through a browser, make sure that you are on the domain rncb.ru. Phishing sites often disguise themselves as official resources, offering a “accelerated” or “modified” version of the application. Remember that original APK file always has a digital signature of the developer, which can be verified after downloading.
If you download the file manually, pay attention to its size and extension. The file must have the extension .apk. After the download completes, the system may issue a warning that the file may be dangerous. This is a standard reaction Android to any executable files received from outside the Play store.
How to check the digital signature of an APK?
To check the signature, you can use special utilities like APK Signature Verifier. The original RNKB application will have a signature that matches the bank’s certificate. If the signature is missing or does not match, the file has been modified and its installation is dangerous.
Do not use torrent trackers or forums to search for banking software. The risk of introducing malicious code in such sources tends to one hundred percent. Free download from an official source is the only safe way to obtain software.
The process of installing an application on a smartphone
After the installation package is saved in the device’s memory, you can proceed with the actual installation. Open the file manager and find the downloaded file in the Download or Downloadsfolder. Clicking on the file initiates the launch of the system package installer.
A window will appear on the screen asking for access rights. The RNKB application will request a number of permissions necessary for its operation. These may include access to the camera (for scanning QR codes), access to the phone book (for quick transfers by number) and access to geolocation. Please read the list carefully before confirming.
| Permission type | Purpose | Responsibility |
|---|---|---|
| Camera | Scanning QR codes for payment | Conditionally required |
| Memory | Saving receipts and statements | Required |
| Phone | Device identification | Required |
| SMS | Automatic reading of confirmation codes | Recommended |
