Card Validator Single Target Area Modular EMV Reader
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card validator systems in transit systems often struggle with user confusion when multiple fare media types are supported, as different reader technologies require distinct target areas, and EMV systems face challenges with rapid technological updates that necessitate full system certification rather than modular component certification.
Innovation Solution
A modular EMV contactless reader is integrated within a housing that shares a single target area with a bar code reader, allowing for separate certification and easy upgrading, and is designed to accommodate various reader technologies such as optical scanners and biometric detectors, enabling users to present cards or documents in a unified manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple different fare media types are supported with separate target areas, then the system can accommodate different reader technologies, but the location for positioning cards is not readily obvious to users and creates confusion
Solution Approach 1:
The patent combines multiple reader technologies (bar code reader and contactless/EMV reader) into a single integrated validator housing with one unified target area. This merging eliminates the need for separate target areas for different media types, making it obvious to users where to present any card while maintaining support for multiple fare media types through the integrated multi-functional reader system.
2Adaptability or versatility
If EMV reader technology is updated rapidly, then the system remains technologically current, but full system certification is required rather than modular component certification
Solution Approach 1:
The patent segments the validator system into modular components, with the EMV contactless reader as a separate replaceable module within the integrated housing. This segmentation allows the EMV reader to be updated independently as a modular component, enabling technology updates without requiring full system recertification, thereby reducing certification complexity while maintaining technological currency.
3Reliability
If separate validation target areas are provided for different reader technologies, then each reader can be optimized for its specific technology, but the physical configuration becomes more complex and requires more space
Solution Approach 1:
The patent implements a universal target area that serves multiple reader technologies (bar code and contactless/EMV readers) simultaneously. The integrated housing design allows a single physical space to accommodate different reading technologies, eliminating the need for separate optimized target areas while maintaining reading accuracy through the multi-functional capabilities of the unified reader system.
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
This solution simplifies user interaction by providing a single target area for multiple reader technologies and allows for evolutionary upgrades of the EMV reader without requiring full system certification, enhancing operational efficiency and user experience in transit systems.
Implementation Method 1
Bar code readers will use an optical beam to discern the presented bar code
Implementation Method 2
Contactless or EMV contactless readers communicate with an embedded chip for ascertaining an identity code as well as other data

AI summary
A card validator includes a plurality of readers for validating a corresponding plurality of card and document types. The validator includes the housing containing the plurality of readers wherein the readers are spaced at different locations within the housing and disposed therein to read cards presented to the card validator at a single target area. The housing is configured to direct a user presentation for the provided card at the signal target area. Each of the individual readers is modular within the housing and is disposed within a modular reception location therein for facilitating performance certification of the modular readers therein separately from certification of the entire multi-card validator system.
