NSB Sri Lanka, Entrust, and DMS Enable Secure, Cardless Payments With Mastercard Pay by Account

NSB wanted to provide customers with more intuitive and accessible payment options, especially for those underserved by traditional card-based systems. The bank envisioned a cardless payment experience that would allow users to make purchases directly from their bank accounts without relying on physical cards, card issuance, or legacy processing infrastructure.

Achieving this vision required overcoming technical and operational hurdles related to mobile wallet integration, secure tokenization, and compatibility with merchant systems.

Key challenges included:

• Delivering a cardless experience: Enable customers to make payments directly from their accounts in a way that was intuitive, secure, and compatible with existing merchant infrastructure.
• Enhancing mobile app capabilities: Upgrade the NSBPay app to support in-store contactless payments via NFC while maintaining a seamless user experience.
• Ensuring rapid and secure deployment: Bring the solution to market quickly without compromising security, compliance, or performance.

To meet these goals, NSB needed technology and implementation partners with expertise in digital payments, mobile wallet integration, and secure tokenization.

NSB selected Entrust, in partnership with DMS, to implement mobile NFC payments leveraging Pay by Account using the Entrust Digital Card Solution. DMS, a long-standing local Entrust partner in Sri Lanka, played a key role in integrating the solution and ensuring smooth deployment within NSB’s existing infrastructure.

Delivered through an SDK, the solution enables customers to digitize their bank accounts within the NSBPay mobile app and make secure, tokenized payments directly from their mobile devices.

Key elements of the solution included:

• Pay by Account: Digitizes and tokenizes the bank account itself, eliminating the need for physical card issuance. NSB had already implemented Mastercard Pay by Account for ecommerce and QR code payments, with mobile NFC marking the third major use case.
• NFC Issuer Wallet: Enables tap-and-pay functionality on Android devices, allowing customers to make in-store purchases from within the NSBPay app.
• SDK Integration: Embeds the Entrust solution into NSB’s mobile app while allowing NSB to maintain control over branding, functionality, and the customer experience.

By leveraging Entrust technology and its collaboration with Mastercard, NSB accelerated deployment and established a foundation for expanding digital services across Sri Lanka.

The solution went live in January 2026, marking a major milestone in NSB’s digital transformation journey. Early indicators point to strong adoption and positive customer feedback.

Key outcomes include:

• Expanded access to digital payments: Customers across Sri Lanka can make secure, contactless payments directly from their bank accounts without needing a physical card. ·
• Increased mobile engagement: The NSBPay app has seen a rise in usage and engagement as customers embrace cardless payments.
• Operational efficiency and fraud reduction: Tokenized transactions help reduce fraud risk and streamline payment processing, contributing to a more secure and scalable infrastructure.
• Greater financial inclusion and strengthened brand leadership: Cardless digital payments expand access to banking services in underserved and remote regions while reinforcing NSB’s position as an innovation-driven financial institution in Sri Lanka.

These results reflect NSB’s commitment to innovation and its ability to deliver meaningful improvements in customer experience and operational performance.
