As the mobile wallet is adopted, a mobile payment scheme emerges, with its users as elements in a network of transfers. In this article, I study the mobile payment scheme of Movii— the first fintech firm in Colombia operating under a financial non-banking license for electronic deposits and payments. Based on a unique dataset of bilateral transfers between Movii’s mobile wallet users, I build, visualize and analyze Movii’s network, daily from November 18, 2017, to November 25, 2020. Besides the anticipated increase in the number of users and the value of transfers, the visual and quantitative complexity of the network of transfers increases over time. This increase in complexity is likely to be linked to the adoption of Movii’s mobile wallet, which results in users finding new ways to use mobile payments beyond person-to-person transfers, including person-to-business and business-to-business. Also, results suggest the Covid-19 pandemic accelerated the evolution of Movii’s mobile payments scheme.32 páginasPDFengOpen AccessWorking paperL14 - Transactional Relationships; Contracts and Reputation; NetworksD85 - Network Formation and Analysis: TheoryE42 - Monetary Systems; Standards; Regimes; Government and the Monetary System; Payment SystemsPaymentsMobileNetworksFintechPaytechComplexitySistema financiero -- Colombia -- 2021Sistemas de pago -- Colombia -- 2021Medios de pago -- Colombia -- 2021Pagos en línea -- Colombia -- 2021Acceso abiertoAtribucion-NoComercial-CompartirIgual CC BY-NC-SA 4.0
