SMART STOCK: desenvolvimento de clientes mobile e web para controle de inventário utilizando RFID

Abstract

Managing the quantity of available goods poses a challenge for companies in the tertiary sector, as systems traditionally provide this variable based on records of inventory changes. The accuracy of such data depends on the correct execution of these records, which are often performed manually. To address this gap, inventory audits are conducted through physical counts to ensure the actual stock corresponds to the balance recorded in the system. Among the various solutions that automate the inventory process, the use of portable Radio-Frequency Identification (RFID) readers is one of the most popular. However, the high acquisition cost of these devices limits their adoption by small and medium-sized enterprises. Within the scope of the EmbarcaTech program, the SmartStock project proposes a low-cost portable RFID reader. The complete system comprises firmware, mobile, backend, and frontend components; this work specifically presents and discusses the development of the system’s web and mobile clients. These interfaces were developed using the Next.js and Flutter frameworks, respectively, ensuring modern and reliable applications. Tests in a controlled environment validated the integration of these clients with the remaining components, resulting in an agile and replicable reader model.
