Enhancing the TWINT Ecosystem to Solidify Its Leading Position as a Mobile Payment Provider in Switzerland

TWINT, a company that owns Switzerland's most popular payment app, partnered with Modeso to strengthen its standing in the mobile payments market through the development of three projects: Digital Voucher, Super Deals, and Storefinder.

Digital Voucher streamlines the purchase of digital vouchers, fostering a seamless connection between merchants and users. Super Deals, building on a similar foundation, offers a diverse array of exclusive deals. Both platforms offer a consistent user experience and secure transaction process, with merchants benefiting from autonomy in managing their offerings. Storefinder, a location-based application, empowers users to discover TWINT-compatible points of sale on a map, for swift and secure payments.

About TWINT – The leading mobile payment provider in Switzerland

TWINT has been at the forefront of transforming the way transactions take place in the country. By seamlessly integrating with banks, TWINT eliminates transaction fees, providing users with a versatile payment app that enables peer-to-peer money transfers and purchases at diverse points of sale, including supermarkets.
With over 5 million active users, TWINT however, faces constant competition from global players, challenging the company's dominance in the market.

The introduction of strategic initiatives like Digital Voucher, Super Deals, and Storefinder is a way for TWINT to retain its user base and stimulate increased transactions.

Digital Voucher

Digital Voucher

Enabling a seamless payment experience for customers

Digital Voucher acts as a bridge connecting TWINT's payment system with merchants looking to showcase their products. Currently, four integrated merchants use this service, providing their customers with seamless payment options. By integrating TWINT's payment capabilities with merchants' offerings in a secure and streamlined manner, we ensure a fraud-resistant environment for users to purchase digital vouchers.

Software development challenges and solutions

The creation of Digital Voucher posed technical challenges. Here's a concise overview of the main difficulties we've faced and the solutions we've implemented.

Technology and implementation process overview

The core team on Modeso's side for Digital Voucher included a lead engineer, a business analyst, and a project manager. Depending on specific needs, we supplemented the team with software developers and QA engineers as required. Here's a quick glimpse into our development process and technology for Digital Voucher:

Software development

Angular
We chose Angular for front-end development as this technology is part of our core technology stack, allowing us to leverage our established expertise, benefit from regular security and functional updates, and access cutting-edge functionality.
GCP
The application is deployed on the Google Cloud Platform. Our DevOps engineers oversee the deployment and maintenance, using Kubernetes to implement automated scaling. This is particularly crucial for Digital Voucher, where user traffic experiences significant variations throughout the month. We used GCP for Super Deals as well. The application experiences increased variability in user traffic during special campaigns, leading to rapid spikes in the number of users within minutes.
Node.JS
Node.js became our preferred technology for the backend, not only because it is a fundamental component of our core tech stack, but also because it is well-suited to handle large amounts of requests while supporting efficient automated scaling with light-weight microservices.
MongoDB
MongoDB with its flexible schema is ideal for online shops, especially when synchronizing products from external systems. It is also designed for horizontal scalability, allowing Digital Voucher app to handle increasing amounts of data and user transactions as the user base and merchant integrations grow. The ability to distribute data across multiple nodes ensures optimal performance and responsiveness.
RabbitMQ
The integration of RabbitMQ, an open-source message broker that enables asynchronous communication between different components of the app, allowed us to implement microservices architecture while improving the flexibility, scalability, and performance of the application.

User acceptance testing (UAT)

As an integral part of our development process, we conducted an extensive user acceptance testing phase, providing TWINT with the opportunity to thoroughly assess the application. The goal was to achieve a consistent and cohesive experience, ensuring users feel as though they never leave the app.

Robust security

We place significant emphasis on personal data privacy regulations, implementing robust fraud prevention measures to safeguard user information. Prioritizing security is crucial for safeguarding reputation because any security issues could potentially affect TWINT.

Penetration testing

Our security measures included penetration tests conducted by an independent third-party provider to identify potential security vulnerabilities. These tests cover various aspects, such as scrutinizing HTTP headers, checking for unprotected endpoints, and ensuring precise access controls. This thorough examination aligns with data privacy regulations, particularly the recent Swiss nFADP law.

Performance testing

We performed performance testing to make sure the application can cater to the growing user base and can manage more than 150,000 orders per hour. This was crucial, especially in scenarios with fluctuating user traffic. We continuously perform performance tests to ensure that organic user growth can be sustained.

Monitoring and alerting

We cooperate with TWINT's operations team and have a vigilant monitoring and alerting system in place to contribute to a seamless and secure operational environment. This active monitoring system allows us to proactively identify potential issues and quickly react to system alerts.
