Self-Checkout Terminal Using RFID Detection for Automated Payment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-checkout systems in retail settings require assistance and scanning of items, which can be inefficient and inconvenient for customers.
Innovation Solution
A self-checkout terminal that uses a mobile device to transmit shopping data and credential information via low-power electromagnetic waves, allowing customers to authorize payments without scanning items and enabling cash dispensing without a card reader, using a combination of automated transaction and point-of-sale functionalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional self-checkout systems require scanning items and store personnel assistance, then item verification accuracy is improved, but checkout efficiency and customer convenience deteriorate
Solution Approach 1:
The system enables customers to complete checkout independently by carrying items to the terminal, which automatically detects items via RFID tags and processes payment without requiring store personnel assistance or manual scanning, thus improving both efficiency and maintaining accuracy through automated item verification
Solution Approach 2:
The patent replaces the mechanical scanning process with RFID electromagnetic field detection, where the terminal automatically detects items carried by customers through RFID tags, eliminating the need for manual barcode scanning while maintaining accurate item verification
2Reliability
If manual scanning and clerk assistance are used, then transaction reliability is improved, but wait time and operational complexity increase
Solution Approach 1:
Items are pre-tagged with RFID tags before reaching the customer, enabling the terminal to automatically detect and verify items as they are carried to the payment area, eliminating the need for sequential manual scanning and reducing wait time while maintaining transaction reliability through automated verification
Solution Approach 2:
The RFID detection process operates continuously as items are carried through the terminal's electromagnetic field, allowing simultaneous detection of multiple items without interruption, thereby reducing checkout wait time while maintaining reliable transaction processing
3Reliability
If card readers and complex authentication systems are used, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system uses RFID tags as an intermediary between the payment system and customer items, enabling automatic item detection and payment processing through simple proximity-based interaction, thereby maintaining security through automated credential verification while significantly improving ease of operation
Solution Approach 2:
The terminal automatically performs authentication and payment processing by detecting RFID tags on carried items and interfacing with payment methods stored on the customer's device, eliminating the need for manual card insertion or complex authentication steps while maintaining security protocols

AI summary
A system provides for a self-checkout terminal with various components. A receiver receives shopping data including prices of items that a customer has physically acquired or placed in a cart. A payment logic receives credential information associated with a monetary account for paying for the items. A message logic creates checkout data that includes data representing the collection of purchase items. A transmitter transmits the credential information to an account network for authentication and the receiver receives a response indicating if the monetary account is valid. The payment logic/self-checkout terminal indicates to the customer that a payment using the monetary account for the purchase items is authorized or not. When authorized, an authorization is received at the self-checkout terminal before the customer arrives at the terminal and the self-checkout terminal causes a payment transaction to be executed to provide for self-checkout using the monetary account without assistance by another person.
