Tá Safe: sistema para rastreabilidade de celulares

Abstract

With the periodic release of new cell phone models, users are replacing their devices more frequently compared to the past. Thus, the supply of these devices in the second-hand market grows due to the number of new ads created daily on sales platforms and social networks. The theft and robbery of these devices follow the growth of the sector, to the point that users looking for second-hand devices have difficulty defining the legitimacy of the device. To solve possible problems when buying a cell phone without proper verification, this project aims to develop a system that offers its users device traceability resources to identify the steps that this device has gone through until it is offered in the used market. With this, demonstrate that the device was originally obtained in a transaction that generated an NF-e and is linked to the CPF of the first owner. After the purchase, the registration is transferred to the new owner, thus creating a new link in the traceability of this device.
