64 ITMS 2019 Yearbook: Solution for International Transaction Networks Authors: Rodrigo Perdomo, Alejandro Rama, Maximiliano Ranuio, and Fernando Zanetti Organization: David Boucher, financial advisor to U.S. corporations Multinational companies create a network in which subsidiaries and affiliates exchange tens of millions of dollars in services and products. This exchange generates thousands of related transactions over a given period, which, once the period closes, are processed and settled. The Clearing House acts as an intermediary between network participants, collecting and paying the various balances resulting from this settlement. The companies within the network never send money to one another; they only pay and receive money from the Clearing House. Given that network management is highly complex at the time of settlement, multinational companies develop or purchase a software solution to manage the network. Over the past two decades, technology has advanced and the network’s operations have changed; however, some corporations still use systems built over 15 years ago to manage this network, suffering the consequences. Based on this, the client, who works for large U.S. corporations, proposed creating ITMS (Intercompany Transaction Management System), an on-premise web product for managing this type of transaction network, taking current needs into account and seeking to validate the solution with one of the companies he advises. The project’s objective was for the system component responsible for recording transactions to support their storage in both a relational database and on the blockchain. The team built this system using .Net Core, Angular 7, Microsoft Azure, MSSQL, and the Hyperledger Fabric blockchain. Degree Program: Systems Engineering Advisor: Diego de León, Eng. MobiPay: In-store payments via cell phones Authors: Matías Besozzi, Fernando Castagno, Nicolás Fierro, Ignacio Harretche, and Guillermo Repetto Organization: Evertec When making electronic payments in stores, there are various solutions that involve the use of a specific device or hardware, such as a POS (Point of Sale). The purpose of this project was to develop an application that allows payments to be made in stores using the smartphones of both buyers and sellers. This way, the seller does not need to purchase additional equipment, while the buyer does not need to have a debit or credit card at the time of payment. The project was presented by PayGroup, a company within the Evertec group, which already markets an electronic payment authorization system. The solution consists of a mobile app for Android and iOS developed with Xamarin for the .NET Core framework, which incorporates both buyer and seller functionalities. It requires internet access and uses the EMVCo standard for QR codes to capture sales information. It also features a backend that exposes a REST API, developed using the .NET Core framework, and hosted on Azure. Its architecture is based on microservices and prioritizes security, both during the transaction and in the protection of stored data. The team built a web client, developed in React, which serves as a back office for both sellers and store owners as well as for system administrators.
