NFC Billing System Using GPS Location Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NFC-based public transportation billing systems incur economic losses when passengers forget to swipe their cards upon exiting, as they are charged for the full journey, leading to unnecessary costs for both passengers and operators.
Innovation Solution
A method and system that utilize a terminal, server, and card machine to generate billing information based on location data, where an end billing request is processed only if the distance between the terminal and the public transportation means exceeds a predetermined threshold, thereby accurately determining when a passenger has exited, and charging accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If passengers swipe cards at beginning and end of travel to determine travel distance, then billing accuracy is improved, but passenger convenience deteriorates due to mandatory end-swiping
Solution Approach 1:
The system automatically detects passenger exit through NFC card detection at the exit gate and GPS location monitoring, eliminating the need for passengers to manually swipe cards. The billing system self-services by automatically calculating travel distance and generating bills based on detected exit events.
Solution Approach 2:
The system continuously monitors GPS location data and NFC card status, providing real-time feedback to determine whether the passenger has exited the vehicle. This feedback mechanism enables automatic billing decisions without requiring passenger action.
2Quantity of substance
If passengers are charged for full journey when forgetting to swipe exit card, then operator revenue is improved, but passenger fairness deteriorates due to overcharging
Solution Approach 1:
The patent replaces the mechanical card-swiping system with an electronic monitoring system using GPS location data and NFC card detection. This substitution enables more precise tracking of actual travel distance and automatic calculation of accurate billing amounts, eliminating overcharging while maintaining operator revenue through systematic monitoring.
3Reliability
If NFC card swiping is mandatory for exit detection, then billing reliability is improved, but system complexity increases due to additional hardware requirements
Solution Approach 1:
The patent makes the mobile phone's NFC module and GPS system serve multiple functions: contactless payment, exit detection, and location tracking. This multi-functionality reduces the need for separate dedicated hardware systems while maintaining billing reliability through the smartphone's existing capabilities.

AI summary
Disclosed are a method for generating billing information, a terminal, a server, and a billing system. The method for generating billing information comprises: receiving an end billing request transmitted by a terminal, the end billing request comprising location information of the terminal and bus information; and executing, on the basis of the location information of the terminal and of the bus information, an end billing operation with respect to a first terminal from which the distance to a bus is greater than a distance threshold.
