POS Fraud Detection via Subset Authorization Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile point-of-sale (POS) devices operating in offline mode can facilitate fraudulent transactions by allowing nefarious operators to store and later upload large batches of payment instrument information, making it difficult for payment services to identify and flag invalid cards in time, leading to potential misuse.
Innovation Solution
Implementing a technique where payment services process only a subset of authorization requests from a batch, determining if it's potentially fraudulent, and refraining from processing further transactions until additional fraud analysis is conducted, thereby limiting the exposure of invalid card information to nefarious operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If payment services process all authorization requests from a batch, then complete transaction processing is achieved, but fraudulent transactions may be facilitated and information exposure to nefarious operators increases
Solution Approach 1:
The patent segments the batch of authorization requests into a subset for initial processing. By selecting and processing only a portion of the batch first, the system can identify fraudulent patterns without exposing all payment instrument information to potential fraudsters, thus resolving the contradiction between complete processing and information protection.
Solution Approach 2:
The patent applies preliminary fraud detection by processing a subset of authorization requests before completing the entire batch. This preliminary action allows the system to identify and flag potentially fraudulent transactions early, preventing further exposure of invalid card information while maintaining the ability to process legitimate transactions.
2Productivity
If payment services process large batches of authorization requests, then productivity is improved, but the load on card payment networks and issuing banks increases
Solution Approach 1:
The patent implements partial action by processing a subset of authorization requests rather than the entire batch at once. This approach maintains productivity by continuing to process transactions while reducing the instantaneous load on card payment networks and issuing banks, effectively resolving the contradiction between high-volume processing and network capacity.
3Speed
If payment services quickly authorize payment instruments, then transaction speed is improved, but fraudulent transactions may occur before detection
Solution Approach 1:
The patent performs preliminary fraud detection on a subset of authorization requests before completing full batch processing. This preliminary action enables the system to maintain fast authorization speeds for initial transactions while simultaneously detecting fraudulent patterns, resolving the contradiction between speed and detection timing.

AI summary
Techniques and arrangements for detecting potentially fraudulent transactions made on a point-of-sale (POS) device. In some instances, the POS device may upload a batch of authorization requests corresponding to transactions made on the POS device while the POS device was in an offline mode. A payment service may receive this batch and, as opposed to processing the entire batch, may select a subset for processing. After selecting the subset, the payment service may attempt to authorize payment instruments associated with each transaction of the subset. The payment service may then compare an amount of declined payment instruments to a threshold. If the amount is greater than the threshold, then the payment service may flag the subset and/or the batch as fraudulent and may refrain from processing further transactions of the batch.
