The Future of USSD in Software Development

Unstructured Supplementary Service Data (USSD) has quietly thrived in the mobile communication industry. Even with the advent of more advanced and modern options, the USSD protocol, a fundamental component of mobile communications for decades, continues to serve a vital function and purpose even in software development. The USSD allows for rapid communication between mobile phones and network operators, facilitating services from balance checks to mobile banking.

However, with the advancement of technology from 5G networks to the Internet of Things (IoT) and artificial intelligence becoming increasingly prevalent, examining the future of USSD in software development and its potential to remain relevant in the changing industry is of the essence. In this article, we explore the significance of USSD, its applications and trends in software development today, its future in software development, and the impact of future changes on software development. 

USSD in software development today 

In software development, USSD is implemented as a communication protocol that enables two-way data exchange between mobile devices and service provider networks, particularly in regions with limited smartphone penetration or unreliable internet connectivity. Developers create USSD applications on telecom networks, accessible through shortcodes (e.g., *123#), to allow users to access various services via simple feature phones.

USSD is widely used for mobile banking, balance inquiries, airtime top-ups, and basic information services. However, its significant role in software development in creating applications for markets where smartphone penetration is low, or internet connectivity is unreliable is one of its key advantages:

1. Accessibility: USSD works on any mobile phone, from basic feature phones to the latest smartphones. It is the ideal platform for developing applications that must reach the broadest possible audience.
2. No Internet required: USSD services do not need an Internet connection, as they function on a primary GSM network. This makes them invaluable in areas with poor or expensive Internet connectivity.
3. Cost-effectiveness: USSD is often more cost-effective than other technologies, particularly in developing markets, for both developers and users.

Current trend for USSD in software development

1. API integration: Developers are increasingly connecting USSD services with external APIs, enabling more complex and data-rich applications and allowing for information retrieval and processing.
2. Enhanced security measures: USSD developers are implementing stronger security protocols, which include encryption, multi-factor authentication, and secure session management.
3. Improved user interface: Despite the text-based limitations, developers are creating more intuitive menu structures and navigation paths, better formatting, more explicit instructions, and a more logical flow of options.
4. Multi-channel integration: USSD is currently linked with other communication channels, such as SMS, voice, and smartphone apps. It creates a seamless experience where users can start transactions on USSD and complete them via other means.
5. AI and machine learning integration: Basic AI is incorporated to personalize user experiences, provide automated responses, and optimize service delivery based on user behaviour.
6. Analytics and data mining: Developers implement analytics tools to track user behaviour, preferences, and pain points. This data is used to improve USSD services.
7. IoT Integration: In some applications, USSD is a simple interface for IoT devices, allowing users to control or receive updates from connected devices via USSD menus.
8. Cloud-based USSD Platforms: The emergence of cloud-based USSD platforms makes it easier and more cost-effective for developers to create and deploy USSD services without managing complex infrastructure.

The Future challenges and opportunities of USSD 

USSD will face several challenges in the coming years:

• Security threats: As USSD continues to be used for sensitive transactions, it will face increasingly sophisticated cyber threats. This challenge presents an opportunity to develop innovative security solutions tailored for USSD.
• Integration with emerging technologies: USSD will likely face the challenge of maintaining its relevance amidst the proliferation of smartphones and high-speed internet connectivity.
• User experience within limitations: Improving user experience within the constraints of USSD’s text-based, menu-driven interface. This limitation could drive innovation in UI/UX design for constrained environments.
• Regulatory compliance: Meeting increasingly strict data protection and financial regulations across different jurisdictions, especially for USSD banking and financial services.
• Bridging the digital gap: This challenge involves balancing the need to serve users with basic phones while catering to smartphone users. It allows for creating adaptive, multi-channel services that seamlessly transition between USSD and more advanced interfaces.

Impact of the future changes of USSD on software development

The evolving role of USSD will have a significant impact on software development practices:

• Changes in development approaches: Developers working with USSD will need to adopt strategies that are different from those used for web or smartphone app development. These include designing for limited screen space, optimizing low-bandwidth environments, and creating intuitive menu-based interfaces.
• New skills required: Developers must improve their skill sets as USSD integrates with newer technologies like AI and blockchain. Understanding the intricacies of the USSD protocol and its integration with these modern technologies will become increasingly important.
• Potential for cross-platform integration: There is growing interest in integrating USSD with other platforms to create hybrid solutions. For example, a service might use USSD for essential functions but switch to a smartphone app for more complex operations when available. 

Predictions for the next decade
