Offline Store Mini Program Case

This case demonstrates how traditional brick-and-mortar stores can leverage mini program technology to create an integrated online-to-offline (O2O) shopping experience, bridging the gap between digital and physical retail.

Project Overview

Project Background

Traditional retail stores face increasing competition from e-commerce platforms. This mini program helps offline stores digitize their operations while maintaining the personal touch of in-store shopping. It enables customers to browse products online, check store inventory, make reservations, and enjoy seamless pickup or delivery services.

Core Features

Store Locator: Find nearby stores with real-time inventory
Product Catalog: Browse store inventory with live stock updates
Reservation System: Reserve products for in-store pickup
Queue Management: Virtual queuing system to reduce wait times
Loyalty Program: Digital membership cards and rewards
In-Store Navigation: Indoor positioning and product location guidance
Staff Assistance: Connect with store staff for personalized service
