Mobile POS Transaction Verification via SMS Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile point-of-sale (POS) systems face increased transaction processing times due to reliance on user input for verification, particularly after payment information is communicated, leading to inefficiencies in communication and verification processes.
Innovation Solution
A computer-implemented method and system for communicating transaction data between mobile devices using SMS connections to register account data, verify device registration, and transmit confirmation messages, enabling pre-authorization and processing of transactions without requiring additional user input after initial verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile POS systems rely on user input for verification after payment information is communicated, then transaction security is maintained, but transaction processing time increases
Solution Approach 1:
The system performs preliminary registration of account data with SMS device data before the actual transaction occurs. This pre-registration establishes the verification framework in advance, so that during the transaction, the system only needs to send confirmation messages via SMS rather than requiring manual user input for verification, thus reducing processing time while maintaining security
Solution Approach 2:
The system enables automatic verification through SMS confirmation messages that are sent and processed without requiring manual user intervention. The mobile device automatically receives and processes the SMS confirmation, allowing the transaction to proceed without the buyer needing to manually engage the mobile device for verification, thereby reducing transaction processing time while maintaining security
2Measurement precision
If mobile POS systems require additional user input for verification, then transaction accuracy is verified, but communication efficiency decreases
Solution Approach 1:
The system replaces the mechanical interaction of manual user input (typing PIN or signature on the mobile device) with an automated SMS message transmission and processing system. This substitution maintains verification accuracy by still requiring user confirmation through SMS while eliminating the inefficiency of manual engagement, thus improving communication efficiency without sacrificing verification accuracy

AI summary
Provided is a computer-implemented method for communicating transaction data between mobile devices, including: registering account data associated with a merchant account corresponding to short message service (SMS) device data associated with a point-of-sale (POS) device, and account data associated with a user account as corresponding to SMS device data associated with a user device; receiving, via an SMS communication connection, transaction data associated with a transaction from the POS device, verifying the POS device and the user device are registered; in response to determining that an account balance of the user account is greater than the transaction authorization limit, transmitting a first confirmation message associated with the transaction, via an SMS communication connection, to the user device to confirm the transaction; and in response to receiving a first confirmation response associated with the transaction, via an SMS communication connection, processing the transaction data.
