    • What’s mobile banking?

      Mobile banking (m-banking) refers to the use of a mobile device to access banking and financial services offered by banks. It enables customers to check their bank account balance, conduct online transactions, transfer funds, pay bills, etc., without visiting banks.

      Is it safe to do online banking on your phone?

      Yes. Download the official banking app, update it constantly, avoid using public Wi-Fi, make sure your bank uses multi-factor authentication and keep your phone close by! However, getting smart about phishing and smishing is a plus.

      How can mobile apps interact with banking systems that are not exposed on the Internet?

      Mobile apps rely on the internet to interact with their back end. In the case of banking apps, this can be a challenge because not all banking systems are exposed on the Internet.

      The industry’s best practice is to deploy a middleware between the mobile and the banking systems. This middleware will expose mobile-friendly API on the internet, while also communicating with banking systems through private networks.

      Through its Digital Banking Platform, Worldline offers such a middleware that is highly suited to the need of the banking industry.
