Project Description

In 2018, Mr. Jerry Nguyen (CEO of Harmony Payment System LLC and HarmonyPay Inc) came to Levinci with the demand to build a POS system integrated with the hardware platform and the payment service that the company was providing.

It is a big and bold idea, which leads to a tremendous change in how hundreds of thousands of small stores operate their businesses. Acknowledging this quest, Levinci established a team with our top-tier individuals to ensure a successful project.

The system was initially defined as 3 separate applications, then Levinci has continuously built and integrated a variety of applications into the Harmony Pay Inc ecosystem to support their diversified sales and service channels, realizing Harmony’s expectations.

Challenges

  • This is a very large and challenging project. We encountered the challenge of digital transformation for a community of users unfamiliar with computer usage or advanced phone features, leading to challenges in cross-platform user experience (UI/UX) design. This matter determines more than 80% of the success of the product.
  • The second major problem to resolve is the integration with peripheral devices. We need to do researches, integrate and continuously keep updated with dozens of peripheral devices of store POS systems prevalent in the market such as card scanners, cash registers, monitors, network routers, etc.
  • The third issue is the system architecture, algorithms and basic design patterns, which must be researched and elaborated from the very beginning.
  • Besides, we overcame many challenges related to team management, quality assurance, operational efficiency in this project.

Results

On May 1, 2019 at Vegas Expo – USA, HarmonyPay Inc launched HarmonyPay Consumer App and Salon HarmonyPay Merchant App on Apple App Store and Google Play Store.
