Abstract(s)
No panorama económico nacional, o combate à fraude e evasão fiscal e aduaneira
desempenham um papel importante na estabilização da economia. Vários esforços têm sido
desenvolvidos ao longo dos últimos anos como forma de garantir uma justa repartição do
esforço fiscal e sancionar sanções do incumprimento. Uma das medidas consiste na
obrigatoriedade de utilização de sistemas de faturação certificados, assim como o programa efatura.
Os sistemas de pontos de venda desempenham na atualidade um papel importante na
estratégia de combate ao incumprimento. Estes sistemas, devidamente certificados, permitem
a emissão de faturas e posterior comunicação à Autoridade Tributária e Aduaneira.
O crescimento sustentado das tecnologias móveis e o aumento da acessibilidade a estes
dispositivos criou várias oportunidades de negócio, conferindo não só mobilidade aos sistemas
de pontos de venda, como também explorar várias funcionalidades.
O objetivo principal desta investigação foca-se no estudo e criação de uma solução para pontos
de venda destinada a dispositivos móveis, recorrendo ao desenvolvimento de soluções
multiplataforma. Para alcançar esse objetivo, foram realizados estudos para determinar as
diversas características inovadoras a implementar. A pesquisa desenvolvida apresenta várias
soluções e abordagens a nível de tecnologias de interação com dipositivos e periféricos, tirando
partido das capacidades dos dispositivos móveis e conferindo novas possibilidades de
automatização de processos.
Como prova de conceito e base para uma solução comercializável foi elaborado um protótipo.
Foram apresentadas em detalhe as várias fases que constituíram o processo de
desenvolvimento da solução, as ferramentas e técnicas abordadas, assim como a proposta de
solução.
Por fim, é feita a discussão dos resultados obtidos e apresentadas as dificuldades, limitações e
perspetivas de trabalho futuro.
In the national economic panorama, the fight against fraud and tax and customs evasion play a vital part in the economy stabilization. Several efforts have been made throughout the last years as a way to guarantee ensure a fair distribution of the tax effort and penalize non-compliance penalties. Both the e-fatura program and the obligation of certified billing systems are some of these measures. The point-of-sale systems (POS) play nowadays an important role in the strategy to fight noncompliances. These systems are properly certified by the Autoridade Tributária e Aduaneira and allow the issuance of invoices and subsequent reporting. The sustained growth and ease of availability of mobile technology has opened several business opportunities, allowing to explore various features besides the ability to allow mobility in these point-of-sale systems. The main purpose of this investigation focuses on the study, design and implementation of a point of sale solution using mobile devices, employing a cross-platform solution. To attain this goal, studies were performed to determinate various innovative features to be implemented. This study presents numerous solutions and approaches to the interaction with the device and its peripherals, taking advantage of the abilities of mobile devices and allowing new possibilities in process automation. As proof of concept and basis to a commercial solution, a prototype was created. The various stages that formed the process of developing the solution, tools used and techniques addressed were presented with details, as the final solution proposal. Finally, the obtained results, difficulties, limitations and perspectives for future work are discussed with some details.
