Design and Implementation of Database Prototype for A Portable Electronic Transaction Device

In recent times, electronic money (e-money) has gained significant popularity in the form of smartphone applications, barcodes, and smart card systems. In previous research, we have developed a smartcard-based device equipped with a dual interface to facilitate electronic transactions using contact or contactless technology. These methods involve initiating a connection with a cloud server, where all transaction data are recorded with full encryption. This device also supports payment activities, as well as checking or topping up account balances by utilizing contact and contactless smart cards, which are produced in Indonesia by PT. Xirka Silicon Technology. The aforementioned research did not explain the significance of a database which actually plays a vital role in the system’s data storage. Therefore, this research aims to provide detailed information on the design of this database. Furthermore, five web pages are designed including, token generator, token list, partner list, payments, and transactions to provide specific services requested by users via a web URL through the database that stores transaction activities carried out by the device.
