Legacy POS Modernization to Improve Store Operations Stability and Scalability<\/h1>

<\/p><\/header>\n\n\n

\n

At one retail company, the long-running POS system was built on VB6 and Access, creating challenges in responding to regulatory and business changes, integrating with peripheral devices, and ensuring maintainability. To expand the potential for future improvements without interrupting store operations, the company needed to understand its existing assets and migrate to a new platform in phases.<\/p>\n\n\n\n

SMILE began by analyzing the existing system and then rebuilt the new POS platform using .NET 8, React 18, and SQL Server. Based on the assumption that stores must be able to operate offline, we organized integration with multiple peripheral devices, including receipt printers, cash drawers, barcode scanners, payment terminals, and customer display devices, creating an architecture designed for future maintenance and expansion.<\/p>\n\n\n\n
