Card Rotation Sequence Authentication for ATMs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional payment terminals and ATMs face inefficiencies and security breaches due to the reliance on Personal Identification Numbers (PINs) and zip codes for user authentication, which can be forgotten or compromised, leading to insecure transactions.
Innovation Solution
Implementing a card rotation sequence as a means of user authentication, where users input a series of card rotations and pauses that are stored and compared to a predetermined threshold, enhancing both efficiency and security by being harder to replicate and less tied to personal information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a PIN or zip code is used for authentication, then the authentication process is simple to implement, but security is compromised because these can be forgotten or easily copied by onlookers
Solution Approach 1:
The patent replaces the mechanical/visual system of keypad entry with a card-based physical manipulation system. Users rotate a card in specific patterns (clockwise, counter-clockwise, left, right) rather than pressing keys, making it harder for onlookers to copy the authentication sequence while maintaining simplicity for the user.
Solution Approach 2:
The patent adds a spatial/directional dimension to authentication by requiring card rotations in multiple directions (clockwise, counter-clockwise, left, right) rather than simple linear key presses. This dimensional complexity increases security against observation while keeping the interaction intuitive for users.
2Reliability
If a PIN is used for authentication, then it is easy to remember for users, but it can be easily compromised and tied to personal information that may be breached
Solution Approach 1:
The patent substitutes the cognitive burden of remembering a PIN with a physical muscle-memory-based card rotation sequence. Users remember patterns of rotation rather than numerical sequences, providing equivalent memorability while significantly improving security against compromise since the physical card manipulation cannot be easily stolen or guessed.
3Productivity
If conventional authentication methods are used, then the transaction process is straightforward, but efficiency is reduced when users forget their PIN or when security breaches occur
Solution Approach 1:
The patent replaces keypad-based authentication with card rotation authentication, which eliminates the common failure mode of forgotten PINs. The physical card manipulation creates a more reliable authentication method that doesn't depend on users remembering numerical sequences, thereby improving transaction efficiency while maintaining high reliability.

AI summary
Systems and methods for authenticating identification information are disclosed. For example, an Automated Teller Machine (ATM) may comprise a user interface. The user interface may comprise a card reader. The card reader may be configured for card rotation about an axis of a bank card. The user interface may be configured to receive card rotation input from a user. The ATM may comprise at least one memory storing instructions. The ATM may comprise at least one processor configured to execute the instructions to perform operations. The operations may comprise receiving identification information from the user. The operations may comprise receiving the card rotation input. The operations may comprise extracting a card rotation sequence from the card rotation input. When the card rotation sequence is within a predetermined threshold from a stored card rotation sequence corresponding to the identification information, the operations may comprise authenticating the user for an ATM operation.
