Fixed-Amount Donation Terminal Using NFC Wireless Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contactless payment systems require user interaction to input information for transactions, which can be inconvenient and time-consuming, especially for donations in high-traffic environments like retail stores or religious services.
Innovation Solution
A wireless payment system using Near Field Communication (NFC) that allows for fast, fixed-amount donations without operator intervention, utilizing a portable donation terminal and administrator PC device for wireless data transmission, enabling automatic processing and receipt generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contactless payment devices are used for donations, then payment convenience is improved, but user interaction is still required to input information which increases transaction time
Solution Approach 1:
The system pre-sets a fixed donation amount that is displayed to the user before the transaction. This preliminary action eliminates the need for users to input amount information during the transaction, reducing interaction time while maintaining convenience. The terminal automatically prepares the payment interface with the predetermined amount already configured.
2Ease of operation
If traditional payment terminals are used for donations, then operator intervention is required which increases complexity, but automated processing reduces operational burden
Solution Approach 1:
The donation terminal is configured to automatically process transactions without requiring operator intervention. The system self-manages the donation amount display, payment processing, and receipt generation. This self-service capability simplifies operation for users while the automated backend handling reduces the complexity burden on operators.
3Productivity
If fixed amount donations are implemented, then transaction speed is improved, but flexibility in donation amounts is reduced
Solution Approach 1:
The system dynamically adapts between fixed and flexible donation modes. While the primary mode uses a predetermined fixed amount for quick transactions, the terminal also allows operators or users to modify the donation amount when needed. This dynamic capability maintains high transaction speed for standard donations while providing flexibility for特殊情况, resolving the contradiction between speed and adaptability.

AI summary
A system and method of setting and charging a fixed donation amount provides a convenient contactless payment for donations. The system includes at least one portable donation terminal and at least one administrator personal computing (PC) device. The portable donation terminal is communicably coupled to the administrator PC device. An administrator may be a cashier, a clerk, a clergy member, and so on. The method begins by outputting a fixed charging amount with the portable donation terminal. Donation information is received through the portable donation terminal. The donation information is processed for the fixed charging amount. An administrator is prompted to generate a receipt of the fixed charging amount for the donation information. At least one remote server may also be communicably coupled to the administrator PC device in order to provide a reference identifier for the receipt. The receipt is outputted with the administrator PC device.
