Electronic Transaction Device Based on Contact Smart Card using Programmable System-on-Chip

The technology advancement brings new innovation on how a secure transaction will be done. In this work, we designed an electronic transaction device using a programmable system-on-chip (SoC). The system development starts by following tasks: 1) designing the hardware part of the device, 2) designing the operating system (OS), and 3) designing the main application as a GUI that uses to check the balance, top up, and make a payment. We also developed the application in the server that serves as a logger. This device used a contact smart to make a transaction.
