Our client is a cornerstone of the Turkish banking sector, serving as a full-service universal bank. In the UK context, they occupy a space similar to large household name a banks in terms of market presence, yet they are internationally recognized for a mobile-first operating model comparable to leading UK digital banks
Updating a registered phone number represents a critical and security-sensitive process for mobile banking customers. In the past, this forced users into high-friction experiences, such as visiting a physical branch or waiting for call center support. These traditional methods not only created significant operational overhead for the bank but also left the process vulnerable to potential fraud risks and social engineering.
To address these challenges, the bank partnered with OBSS, a technology consultancy with over 20 years of deep expertise in the banking sector and a proven track record across more than 10 major bank references, to design and deliver a high-assurance mobile recovery flow.
Drawing on OBSS’s specialist Mobile Banking capability and end-to-end software delivery model, the solution leverages NFC-based chip ID verification and advanced face recognition with liveness detection. This allows customers to securely verify their identity and update their registered phone number directly through the mobile app, without relying on traditional channels. By removing the need for human intervention, the update process can be initiated and completed without requiring a standard login, making it both faster and more secure.
Key Solutions
Users securely scan the embedded chip in their eID/Passport via their smartphone’s NFC reader.
Biometric Authentication
Face recognition with liveness detection ensures the person presenting the ID is the actual owner.
Direct-to-App Integration
Customers update their sensitive contact information directly within the mobile environment delivered by OBSS through their turnkey software development model, bypassing the need for human intervention or traditional authentication.
Working in close partnership with OBSS, the bank successfully transitioned the process into a fully self-service, mobile-first experience, significantly reducing operational dependency. OBSS’s expert engineers and agile delivery approach ensured the solution was built to the bank’s exacting security and compliance standards. This shift has simultaneously improved transaction speed, security, and the overall customer experience. Secure phone number updates that once took substantial time can now be completed within minutes, ultimately supporting higher digital adoption and deeper customer engagement across the platform.
