Smart Control of Expenses Using Mobile Devices

Abstract

It is estimated that only 3.1% of the Brazilian population controls their expenses through digital applications. While 8.9% does not use a digital platform due to a lack of knowledge, 8.1% do not have time. Considering the current usage levels, applications providing a more automated control of expenditures would simplify this task for an average user, making mobile applications a more attractive option. Using digital image processing techniques, optical character recognition (OCR), and post-processing a novel software was developed in Android for receipts automatic recognition allowing mobile users to monitor expenses using photos. Information recognized by the application replicated a real receipt with an acceptable level of similarity.
