Braille Layout for Financial Cards with Segmented Account Numbers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Financial services cards, such as credit and debit cards, face challenges in accommodating braille due to limited space, especially when featuring electronic chips, making it impractical to record essential information like account numbers and expiration dates in a format that can be read by visually impaired individuals.
Innovation Solution
A braille layout is implemented on financial services cards with multiple rows of braille-encoded characters, where the account number is distributed across two rows, and additional information like security codes and expiration dates are encoded in a third row, adhering to specific dimensions to ensure readability and compatibility with existing card formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard braille format is used to record information on the card, then visually impaired individuals can read the information, but the limited space on the card (especially with electronic chips) cannot accommodate the braille characters
Solution Approach 1:
The account number is divided and distributed across multiple rows of braille characters. The first row contains the first six digits, the second row contains the next six digits, and the third row contains the remaining digits plus additional information. This segmentation allows the complete account number to be encoded within the limited card space while maintaining standard braille format for readability.
2Adaptability or versatility
If braille characters are added to the card, then accessibility is improved, but the card design becomes more complex and space for other features is reduced
Solution Approach 1:
The braille characters are positioned in specific locations on the card surface, primarily in the lower portion where they do not interfere with the electronic chip or other critical features. The raised braille dots are strategically placed to provide tactile readability while maintaining the overall card design integrity and functionality of other card elements.

AI summary
Implementations of the present disclosure include a financial services card including a card substrate, and multiple rows of braille-encoded characters formed on the card substrate, at least a portion of the braille-encoded characters encoding an account number that is associated with the financial services card being distributed between a first row and a second row of the multiple rows, and additional information associated with the financial services card being braille-encoded in a third row.
