O2 Digital Banking allows you to aggregate all your financial accounts, including those from other banks, into a single view. It provides tools to manage your finances, track transactions, make payments, transfer money, and deposit checks.
Key features include aggregating accounts from multiple institutions, organizing transactions with tags and photos, setting balance alerts, making payments, transferring funds, mobile check deposit, debit card management, and viewing monthly statements.
The app itself is free to download and use. However, it is designed for enrolled Old Second National Bank digital banking users. Any associated costs would be related to your banking services with Old Second National Bank, not the app directly.
The app is available for mobile devices. It supports secure login options like a 4-digit passcode and fingerprint or face reader on supported devices, indicating compatibility with modern smartphones and tablets.
You can use O2 Digital Banking to get a consolidated view of all your accounts, track spending by adding tags and notes to transactions, set up alerts for low balances, and conveniently make payments or deposit checks from your phone.
