Parking Validation Card Using Stored Codes to Prevent Fraud
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking validation methods are susceptible to fraud and require complex, costly solutions, especially when entities do not have integrated communication systems for validating parking transactions.
Innovation Solution
A multi-function transaction card with a radio frequency component and integrated circuit chip, equipped with a parking validation applet, communicates with transaction and exit terminals to securely store and transmit validation codes, reducing fraud by ensuring codes are only provided after legitimate transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional parking validation methods are used, then the system is simple to implement, but the system is susceptible to fraud and lacks security
Solution Approach 1:
The transaction card is designed to perform multiple functions: it serves as both a payment instrument for transactions and as a parking validation device. The card contains an application that can store and transmit validation codes, eliminating the need for separate validation systems while maintaining security against fraud through cryptographic mechanisms.
2Reliability
If complex validation systems are implemented to prevent fraud, then security is improved, but the system becomes costly and complex to operate
Solution Approach 1:
The transaction card autonomously performs validation functions by storing validation codes locally and transmitting them to exit terminals without requiring manual intervention or complex backend systems. The card's application automatically manages the validation process, reducing operational complexity and costs while maintaining security through self-contained cryptographic verification.
3Reliability
If multiple interactions are required for parking validation, then thorough verification is achieved, but the process becomes time-consuming and inefficient
Solution Approach 1:
The validation code is stored in the transaction card in advance during the initial transaction at the point of sale. When the card is presented at the exit terminal, the pre-stored validation code is immediately transmitted and verified, eliminating the need for multiple back-and-forth interactions and reducing validation time while maintaining thorough verification through cryptographic checks.

AI summary
In some implementations, a card may communicate with an exchange terminal to complete the first exchange associated with an entity, wherein the first exchange is associated with the entity providing a validation of a second exchange associated with a charge for parking a vehicle. The card may receive, from the exchange terminal, an indication of the validation code based on communicating with the exchange terminal to complete the first exchange, wherein the validation code indicates the validation of the second exchange. The card may store the validation code and a time indicator associated with receiving the indication of the validation code. The card may transmit, to an exit terminal, an indication of the validation code and the time indicator to cause an amount associated with the second exchange to be at least partially reduced, wherein the exit terminal is associated with completing exchanges for vehicles parked in the location.
