Contactless Payment Data Acquisition on Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for secure transactional payment processing on smart mobile terminals are inefficient due to the complexity of entering bank card data, especially on small screens, and lack effective authentication, leading to a limited conversion rate and security concerns.
Innovation Solution
A method that utilizes a contactless data reading module on a communications terminal to automatically acquire and process payment data, generating a current authentication code for secure transaction processing, which simplifies data entry and enhances security by using existing entry areas without requiring new application development.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual entry of bank card data is used on mobile terminals, then data input is possible, but the operation becomes complicated and conversion rate decreases
Solution Approach 1:
The system automatically retrieves and fills payment data without requiring manual user input. The mobile terminal autonomously accesses stored bank card information and populates the payment form fields, eliminating the need for users to manually enter sensitive financial data on small screens.
Solution Approach 2:
Bank card data is pre-stored and prepared in the mobile terminal before the actual payment transaction. The system performs preliminary retrieval and validation of payment information, so that when the payment interface is displayed, the data is already ready for automatic insertion without requiring real-time user input.
2Adaptability or versatility
If browser-based payment entry is used, then accessibility is improved, but security and authentication are insufficient
Solution Approach 1:
The mobile terminal acts as an intermediary between the user and the payment processing system. It securely stores authentication credentials and bank card data locally, then automatically retrieves and transmits this information through the browser interface without exposing sensitive data to the merchant's website or requiring manual entry by the user.
3Productivity
If contactless reading is implemented, then data entry speed is improved, but system complexity increases
Solution Approach 1:
The mobile terminal utilizes its existing contactless communication capabilities (such as NFC) originally designed for other purposes and applies them to automatic payment data retrieval. This approach leverages already-present hardware and protocols, avoiding the need for specialized dedicated reading devices or complex custom communication protocols.
Data Source
AI summary
A method for securing the processing of transactional data is disclosed. The method is implemented within a communications terminal comprising a transactional data processing module. The method has: a step for the detection, by the processing module, of a display of at least one entry area relating to a piece of payment means data; a step for the activation, by the processing module, of a contactless data reading module; a step for the obtaining, by the contactless data reading module, of at least one piece of payment means data coming from a payment means; and a step for the furnishing, at said at least one entry area, of at least one piece of payment means data previously obtained.
