Secure Wireless Transaction Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transaction processes in retail and hospitality industries are cumbersome, especially during checkout, as customers often wait in line or at their tables for payment processing, and lack real-time visibility into their purchase items, with limited awareness of promotional schemes.
Innovation Solution
Establishing a secure wireless connection between merchant and customer devices for synchronized shopping carts, enabling real-time updates and payment processing through secure Bluetooth low energy connections, allowing customers to check out electronically and receive electronic receipts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual checkout process is used at POS terminals, then payment can be processed through traditional methods, but customers experience long waiting times and cumbersome procedures
Solution Approach 1:
The system performs preliminary actions by pre-synchronizing the shopping cart data to the customer's mobile device before the actual checkout process. This allows the checkout to be initiated remotely and processed asynchronously, eliminating the need for customers to wait in physical queues at POS terminals.
Solution Approach 2:
The mobile device acts as an intermediary between the customer and the POS terminal. It receives shopping cart data, stores it locally, and enables checkout operations without requiring continuous connection to the terminal, thus decoupling the customer from the checkout queue.
2Ease of operation
If customers wait at the table for payment processing, then payment can be completed, but the process is tedious and time-consuming
Solution Approach 1:
The system enables self-service checkout by allowing customers to initiate and complete payment operations independently through their mobile devices. The shopping cart is automatically synchronized and payment can be processed without requiring merchant intervention or customer presence at the terminal.
Solution Approach 2:
The shopping cart data is preliminarily synchronized to the customer's mobile device, enabling them to perform checkout operations at their convenience without waiting for the merchant to prepare the bill or for payment processing to be initiated at the terminal.
3Loss of information
If traditional POS systems are used, then transactions can be processed, but customers lack real-time visibility of their purchase items
Solution Approach 1:
The system creates a digital copy of the shopping cart data on the customer's mobile device. This copy is kept synchronized with the terminal's cart, allowing customers to view their purchases in real-time without adding significant complexity to the existing POS system architecture.
4Productivity
If manual checkout procedures are followed, then payments can be processed with voucher and discount applications, but the process becomes increasingly tedious
Solution Approach 1:
The mobile application automatically handles complex checkout operations including voucher application, discount calculation, and payment processing. Customers simply initiate the checkout through the app, and the system manages all the tedious operations automatically, improving both efficiency and simplicity.
Solution Approach 2:
Promotional information and voucher details are preliminarily loaded into the mobile application, allowing the system to automatically apply relevant discounts and promotions during checkout without requiring manual intervention or complex customer input.

AI summary
A method for conducting a transaction between a merchant and a customer, a merchant device, and a computer storage medium for instructing a computing device to execute a method for conducting a transaction between a merchant and a customer are disclosed. The method includes establishing a secure wireless connection between a merchant device and a customer device, real-time synchronizing, via the secure connection, a shopping cart of the customer between the merchant and the customer devices, determining, via the secure connection, at least one payment option for checking out the shopping cart, and processing, at a transaction processing device, the payment based on a selected payment option out of the at least one payment option.
