Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automated banking machines face issues with magnetic stripe cards, including wear, duplication, and maintenance challenges due to physical contact, which can lead to fraud and reduced reliability, and are limited by the space required for contact-type card readers.
Innovation Solution
The implementation of a contactless card data reader, such as an RFID card reader, which allows for secure, efficient, and space-saving data retrieval without physical contact, enabling enhanced machine reliability and reduced maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact-type card readers are used to read magnetic stripe cards, then data can be retrieved, but wear, duplication, and maintenance issues occur due to physical contact
Solution Approach 1:
The patent replaces the mechanical contact-based magnetic stripe reader with a contactless RFID reader that uses electromagnetic fields to read card data. This substitution eliminates physical contact between the reader and card, thereby preventing wear on both the card magnetic stripe and the reader's read head, while also reducing the risk of fraud through duplication.
2Ease of operation
If contact-type card readers are used, then data retrieval is possible, but maintenance challenges and reduced reliability result from physical contact
Solution Approach 1:
The contactless RFID reader eliminates the mechanical read head that requires maintenance in traditional magnetic stripe readers. By using electromagnetic induction to read card data without physical contact, the system reduces maintenance needs while maintaining ease of operation for data retrieval.
3Reliability
If contact-type card readers are used, then data can be read, but space required for the reader increases
Solution Approach 1:
The contactless RFID reader uses electromagnetic fields that can penetrate through the card housing material, eliminating the need for a large mechanical read head that physically contacts the card. This allows for a more compact reader design while maintaining or improving security through contactless authentication.
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
The contactless card reader system enhances security, reduces maintenance needs, and increases the functionality of automated banking machines by allowing for more compact designs and improved user experience through faster transactions and reduced wear on both cards and readers.
Implementation Method 1

AI summary
A banking system operates responsive to data read from data bearing records. The system includes an automated banking machine comprising a card reader. The card reader includes a movable read head that can read card data along a magnetic stripe of a card that was inserted long-edge first. The card reader includes a card entry gate. The gate is opened for a card that is determined to be properly oriented for data reading. The card reader can encrypt card data, including account data. The machine also includes a PIN keypad. The card reader can send encrypted card data to the keypad. The keypad can decipher the encrypted card data. The keypad can encrypt both deciphered card data and a received user PIN. The card data and the PIN are usable by the machine to authorize a user to carry out a financial transfer involving the account.
