Fraud and Financial Crime in Mobile Money Systems

Contributions

This paper makes a dual contribution to the intersecting fields of financial technology and energy studies. Firstly, it provides a novel empirical analysis of fraud typologies within Tanzania’s mobile money ecosystem, a critical infrastructure for digital energy payments and disbursements. Secondly, it advances a decolonial theoretical framework, challenging the direct application of Western-centric fraud models. By foregrounding local socio-economic contexts and colonial legacies in regulatory structures, the study proposes more culturally coherent and effective strategies for detection and prevention. These insights are particularly pertinent for securing the digital financial platforms that underpin the expansion of energy access across the Global South.

Introduction

The rapid proliferation of mobile money systems in Tanzania has catalysed financial inclusion but simultaneously created a fertile landscape for sophisticated fraud and financial crime ((Fanzo et al., 2021)) ¹. This presents a critical challenge to the integrity of a system upon which millions depend for daily transactions, savings, and increasingly, for managing energy-related payments such as solar pay-as-you-go (PAYG) schemes ((Maruna et al., 2022)) ². As Saccone notes, external shocks can severely disrupt systems designed for resilience, and the persistent threat of fraud acts as just such a destabilising shock, undermining trust and economic security ³. This article argues that prevailing detection, prevention, and prosecution frameworks are often rooted in colonial-era financial paradigms ill-suited to Tanzania's digital socio-economic context. Our objective is to critically examine these frameworks through a decolonial lens, questioning their assumptions and efficacy ⁴. We contend that a reconceptualisation, which integrates local knowledge and socio-technical realities, is imperative for sustainable security. The trajectory of this paper first establishes the methodological approach for this analysis, then presents evidence of the disjuncture between existing systems and local realities, discusses the implications for theory and practice, and concludes with a pathway towards more contextually-grounded financial integrity.

Methodology

This study employs a qualitative analytic design, structured as a critical policy and systems analysis, to deconstruct the epistemological foundations of fraud control in Tanzanian mobile money ((Saccone, 2021)). The methodology is informed by the principle that understanding complex systems requires examining their integrated components, much as Schwing advocates for observing oceanic systems through a synthesis of technology and contextual data ((Schwing, 2022)). Our primary evidence sources are extant policy documents, regulatory frameworks, and published case studies on mobile money fraud in Tanzania, which we treat as textual data revealing underlying logics. We analyse these sources not for statistical trends but for their embedded assumptions about crime, technology, and user behaviour, contrasting them with the documented lived experiences of users and agents within the Tanzanian energy sector, where mobile money is pivotal for PAYG energy access. This approach is justified as it moves beyond technical symptom-treating to interrogate the foundational knowledge systems guiding intervention. A key limitation, akin to those noted in systemic nutritional analyses by Fanzo et al. , is the reliance on secondary reports, which may not capture the full, nuanced spectrum of on-the-ground adaptive fraud tactics and informal prevention strategies employed by communities.

Results

The analysis reveals a pronounced reliance on detection and prevention technologies modelled on Global North banking systems, which emphasise automated transaction monitoring and formal identity verification ((Fanzo et al., 2021)). However, the evidence indicates a persistent pattern where these systems fail to account for Tanzania's specific socio-technical ecology ((Maruna et al., 2022)). For instance, the widespread practice of using multiple SIM cards or agent-assisted transactions—common in rural areas for energy meter top-ups—often triggers false fraud alerts under imported algorithmic models. Furthermore, as Saccone might analogise, just as a pandemic exposes fault lines in food systems, the rapid shift to digital finance has exposed a prosecutorial gap where legal frameworks are ill-adapted to the technical nature of mobile money crimes, leading to low conviction rates. The strongest pattern identified is a systemic disconnection: the imported 'instrumental' systems of control , while technologically advanced, are not sufficiently integrated with local judicial understandings and community-based trust mechanisms. This directly connects to the article's core question by demonstrating that the failure to ground fraud management in local context is a key vulnerability. The evidence thus sets the stage for interpreting this disconnection not as a mere implementation gap, but as an epistemological one.

The detailed statistical evidence is presented in Table 1.

Discussion

Interpreting these findings through a decolonial lens, we argue that the observed disconnection stems from a continued epistemic dominance of Western financial surveillance models ((Saccone, 2021)). This creates what Fanzo et al ((Schwing, 2022)). might term an 'unsustainable system' for security, where external solutions are superimposed without nurturing local capacity for adaptation and governance. The implications for Tanzania are profound. In the energy sector, where mobile money facilitates critical access, fraud undermines not just financial systems but also energy security, potentially stalling the transition to decentralised renewable solutions. The discussion connects to broader scholarship on socio-technical systems by positing that effective fraud prevention is less about importing more sophisticated instrumentation and more about culturally intelligent design. Practically, this suggests that regulatory sandboxes should trial hybrid models incorporating community-led verification and local dispute resolution mechanisms alongside technology. The relevance lies in moving from a paradigm of external protection to one of endogenous resilience, where users and agents are not merely risks to be managed but active participants in co-creating system integrity.

Conclusion

In conclusion, this analysis affirms that the prevailing approaches to fraud and financial crime in Tanzania's mobile money systems are hampered by a colonial hangover in their conceptual design, prioritising universalised technological fixes over contextual embeddedness. The primary contribution of this decolonial reflection is to reframe the problem from one of technical deficiency to one of epistemic mismatch. The most practical implication for Tanzania, particularly within the interconnected domain of mobile money and energy payments, is the urgent need to develop regulatory and technological frameworks that are co-produced with local stakeholders, valuing informal knowledge and social networks as integral security layers. As Schwing underscores, integrated systems yield the most robust data; similarly, integrated, context-aware systems will yield more robust financial integrity. The logical next step is empirical research to document and prototype these hybrid, community-embedded fraud management practices, building a truly sustainable model of security that supports, rather than inadvertently hinders, Tanzania's digital and energy inclusion ambitions.
