Shopping Cart ID Verification for Payment-Approved Store Exit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Markets and stores face challenges in ensuring payment verification for shopping carts to prevent shoppers from leaving without paying, particularly in autonomous or self-checkout scenarios, which affects the efficiency and security of the shopping experience.
Innovation Solution
Implementing shopping carts with electronic ID tags and a checkout system that includes a checkout processor and exit processor, along with ID tag readers and automatic barriers, to ensure payment verification and control cart movement through the store exit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous self-checkout process is implemented, then productivity is improved, but reliability deteriorates due to payment verification issues
Solution Approach 1:
The system writes an approval indication to the electronic ID tag at the checkout counter before the shopper exits. This preliminary action ensures that payment verification is completed in advance, allowing rapid exit without compromising reliability.
Solution Approach 2:
The patent introduces an electronic ID tag as an intermediary carrier that stores payment approval information. The tag acts as a mediator between the checkout system and exit verification system, enabling reliable payment confirmation without slowing down the autonomous checkout process.
2Reliability
If payment verification is enhanced, then reliability is improved, but device complexity increases
Solution Approach 1:
The electronic ID tag serves multiple functions: it identifies the shopping cart at the checkout counter, stores payment approval information, and enables verification at the exit. This multi-functionality reduces the need for separate verification devices, thereby limiting the increase in system complexity.
Solution Approach 2:
The system uses the shopping cart's own electronic ID tag to store and carry payment verification information. The cart essentially verifies itself at the exit by presenting its own tag, eliminating the need for additional verification equipment and reducing overall system complexity.
3Ease of operation
If autonomous shopping is facilitated, then ease of operation is improved, but harmful factors increase due to unpaid shopping carts
Solution Approach 1:
The system provides immediate feedback by writing payment approval to the electronic ID tag at checkout. At the exit, the system reads and validates this approval indication, creating a closed-loop feedback mechanism that ensures payment is confirmed before the shopper leaves, thereby eliminating unpaid shopping carts while maintaining ease of operation.

AI summary
A system and methods for shopping checkout includes shopping carts, on which are affixed one or more shopping cart identification (ID) tags; a checkout counter that includes a payment register and a checkout processor, and a store exit that includes an exit ID tag reader, an exit processor, and an alert device. The checkout processor is configured to receive payment approvals from the payment register, to receive ID values of shopping cart ID tags, and responsively to generate shopping cart approval records. The exit processor is configured to determine ID values of shopping cart ID tags from output of the exit ID tag reader, to confirm whether or not the ID values correspond to the shopping cart approval records, and, if not to signal a lack of approval at the alert device.
