Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current magnetic stripe cards cannot be used for payments between individuals due to the lack of a mobile device-compatible reader, limiting personal transactions beyond merchant-based systems.
Innovation Solution
A miniaturized card reader connected to a mobile device that can reliably read magnetic stripe cards, enabling financial transactions between individuals by decoding the data and facilitating payments through a mobile device-based system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If magnetic stripe cards are used for payments, then financial transactions can be conducted at merchant locations, but payments between individuals are not possible due to lack of mobile device compatibility
Solution Approach 1:
A mobile device with integrated card reading capability serves as an intermediary between the magnetic stripe card and the payment network. The mobile device reads the magnetic stripe data, processes the transaction information, and communicates with the payment service provider, enabling individual-to-individual payments without requiring traditional merchant point-of-sale terminals.
Solution Approach 2:
The mobile device is designed to perform multiple functions: it can read magnetic stripe cards, process contactless NFC payments, store multiple card accounts, and facilitate various types of transactions including peer-to-peer payments, online purchases, and mobile commerce. This multi-functionality replaces multiple separate devices and systems.
2Reliability
If traditional card readers are used, then magnetic stripe cards can be read reliably, but the readers are too large to be integrated with mobile devices
Solution Approach 1:
The card reading function is segmented from the traditional standalone reader and integrated into the mobile device. The magnetic stripe reading capability is divided into separate functional modules within the mobile device, allowing the reader to be miniaturized while maintaining reading reliability through dedicated reading heads and processing circuits.
Solution Approach 2:
The card reading functionality is nested within the mobile device structure. The magnetic stripe reader, NFC antenna, and processing circuits are integrated into the mobile device's internal architecture, with the reading head positioned to access cards placed on the device surface, creating a compact nested arrangement.
3Loss of information
If magnetic stripe data is read traditionally, then transaction data can be obtained, but the data must be decoded through complex processes at merchant terminals
Solution Approach 1:
The mobile device performs preliminary data capture and validation when the card is swiped or placed on the device. The magnetic stripe data is read and initially processed at the point of interaction, with essential transaction information extracted and validated before transmission to the payment network, reducing the complexity of downstream processing.
Solution Approach 2:
The traditional mechanical card-swiping process through a slot is replaced with contactless NFC technology and simplified magnetic stripe reading. The mobile device uses electromagnetic fields and integrated circuits to read card data without requiring physical card insertion or complex mechanical decoding mechanisms, substituting mechanical systems with electronic and electromagnetic approaches.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and secure financial transactions between individuals using magnetic stripe cards, eliminating the need for cash or checks and allowing for payments to be made through a mobile device, enhancing personal transaction capabilities.
Implementation Method 1
The magnetic stripe card is capable of storing data by modifying the magnetism of magnetic particles embedded in the stripe. The data stored on the magnetic stripe may be sensed or read by swiping the stripe past a read head.

AI summary
A method of paying a second party is provided. A first party accesses the names of one or more qualified second parties. The qualified second parties are second parties that, (i) have an association with the payment service, and (ii) second parties that if they do not have an established association with the payment service then they have established one prior to payment. The first party has an association with the payment service. A tab is opened by the first party that can be selected by the qualified second party at any geographic location of a first party's mobile device. The qualified second party is only able to charge a first party's financial account when the first party's mobile device is within a defined geographic area. The tab is a relationship between the first party, the payment service and the qualified second party, The qualified second party can engage in a financial transaction with the first party is within the defined geographic area.
