The study aimed to develop an advanced smart e-loader device that could automatically assist customers. The device sought to address the following issues: (a) capability of displaying the remaining balances of the load wallet, (b) capability of loading even with a power interruption.
The study was completed through a two-phase approach: experimental development and descriptive approach. The functionality of the device was assessed by ten purposively chosen evaluators.
Findings showed satisfactory results in terms of the featured characteristics such as accepting eleven digits of mobile phone number when loading, accepting 5-peso coins only, displaying the remaining balance of the load wallet, and loading even with a power interruption.
