Virtual Cart System for Retail Queue Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-store purchasing processes are hindered by long lines at point of sale (POS) devices, leading to lost sales and customer frustration, particularly in industries like retail and restaurants, where surges in customers result in slow and inefficient payment transactions.
Innovation Solution
A virtual-cart system that allows users to create a unique account upon entering a retail location, enabling them to select items using a device and generate a mirror cart with item listings and invoices, which can be updated and checked out via a designated POS terminal, minimizing wait times by providing an optimized arrival time for payment based on location and queue management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional point of sale terminals are used for in-store purchasing, then payment transactions can be completed, but long lines form causing increased wait times and customer frustration
Solution Approach 1:
The system performs preliminary actions by allowing customers to scan items and build their cart before reaching the POS terminal. The cart is created and items are registered in advance during the shopping process, so that when the customer reaches the terminal, only payment processing remains, dramatically reducing wait time.
Solution Approach 2:
The purchasing process is segmented into distinct phases: item scanning and cart building (performed throughout the store), queue management (optimized arrival time calculation), and payment processing (at the terminal). This segmentation allows parallel processing of multiple customer carts while maintaining efficient payment throughput.
2Productivity
If more point of sale terminals are deployed to handle customer surges, then transaction capacity increases, but device complexity and operational costs increase
Solution Approach 1:
The system implements self-service by enabling customers to autonomously scan items, build their own carts, and manage their shopping process without staff intervention. The mobile device acts as a self-service terminal, eliminating the need for additional staffed POS terminals while maintaining high transaction capacity.
Solution Approach 2:
The mobile device serves multiple functions: it acts as an item scanner, cart manager, queue optimizer, and payment terminal. This multi-functionality replaces the need for dedicated POS terminals, reducing infrastructure complexity while maintaining productivity.
3Reliability
If customers manually queue at POS terminals, then payment processing occurs in sequence, but lost sales occur due to customer abandonment and frustration
Solution Approach 1:
The system provides continuous feedback to customers through the mobile application, including real-time cart totals, optimized arrival time recommendations, and queue status updates. This feedback loop keeps customers informed and engaged, reducing abandonment and ensuring payment completion.
Solution Approach 2:
The system dynamically adjusts the optimized arrival time based on current store conditions, customer location, and predicted checkout traffic. This dynamic approach allows the system to adapt to changing conditions, maintaining high payment completion rates while preventing customer frustration from excessive waiting.

AI summary
Systems and methods for dynamic creation of virtual-cart enabled purchasing in an in-store environment and automated product recommendation are disclosed herein. Virtual cart enabled purchasing can include receiving a user identifier and creating a mirror-cart linked with the received user identifier. An entry in the mirror-cart can be generated corresponding to a physical item selected for purchase by the user, and an invoice including pricing information for to items in the virtual-cart can be generated. A request for the invoice can be received, and the invoice can be transferred to the point of sale terminal. A payment confirmation can be received indicating completion of transacting of payment for the items in the virtual-cart and tracked in the invoice.
