Temporary Barcode Sticker for Secure Electronic Payment Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for secure monetary and credit transactions lack effective mechanisms to prevent unauthorized access and ensure temporal validity of identification codes.
Innovation Solution
The use of temporary tattoos or stickers carrying barcodes or two-dimensional data matrix codes, which are valid only for a predetermined time period, coupled with a smartphone-based identity confirmation system, ensures secure and temporal validation of transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional identification methods (credit cards, IDs) are used for transactions, then ease of operation is maintained, but security and reliability are compromised due to unauthorized access and lack of temporal validity
Solution Approach 1:
The system pre-generates a sequence of valid identification codes and stores them in a database with temporal validity markers. Before transactions occur, the next expected code in the sequence is predicted and stored for verification, enabling rapid validation without complex real-time computation during the transaction moment.
Solution Approach 2:
The patent replaces physical identification media (credit cards, ID cards) with a digital code verification system. Instead of mechanically checking physical cards against databases, the system uses automated optical scanning and digital sequence validation, substituting mechanical card handling with electronic image processing and database comparison.
2Reliability
If identification codes remain valid indefinitely, then ease of operation is improved, but security deteriorates due to inability to prevent unauthorized use over time
Solution Approach 1:
The system implements periodic validation by assigning temporal validity markers to each identification code in the sequence. Codes are valid only for specific time intervals or transaction windows, automatically expiring after use or time elapse. This periodic validity mechanism ensures that even if codes are compromised, they become useless after their valid period expires.
3Reliability
If frequent card replacements are implemented to enhance security, then reliability improves, but productivity decreases due to operational disruptions
Solution Approach 1:
Instead of replacing the entire identification medium frequently, the system segments the identification function into a sequence of individual codes. Each code can be independently validated and expires after use, allowing continuous transaction flow without requiring physical replacement of the identification card. The sequence provides built-in segmentation that maintains security while ensuring operational continuity.
4Reliability
If complex verification procedures are used to prevent guessing, then security improves, but device complexity increases
Solution Approach 1:
The system creates a digital copy of the expected identification code in the database before the actual transaction occurs. During verification, the scanned code is simply compared against this pre-stored copy using direct string matching or hash comparison. This copying approach replaces complex cryptographic verification with simple equality checking, maintaining high security through sequence prediction while minimizing computational complexity during the actual verification moment.

AI summary
A method is presented for facilitating sales transactions by electronic media. A barcode or other design containing merchant seller information is attached to a decal, label or stamp sheet to enable electronic payment to a merchant seller's account. The decal sheet is made with an adhesive sufficient to allow the decal label once printed, to be attached to a personal object during the period of time for which a financial transaction might occur. The decal label is then removed from the decal label sheet and applied to the personal object provided by the merchant. Before the sales transaction can be consummated, the decal label information is scanned by the buyer's smartphone. Characteristics about the decal label are compared to characteristics about the decal label's information digitally stored on a computer database in question in order to validate the identity of the merchant seller. Once merchant seller's information is validated, the seller may be authorized to debit (or cause a charge) the buyer's electronic account in order to consummate the transaction or transactions. The seller's electronic merchant bank account may be similarly updated.
