Contactless RFID Card Reader for ATM Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic stripe cards in automated banking machines are prone to wear and duplication, leading to increased fraud risks and maintenance needs, and their physical contact with card readers can cause dirt accumulation and limited machine functionality.
Innovation Solution
Implementing a contactless card data reader using RFID technology, which allows for secure, reliable, and efficient card data retrieval without physical contact, reducing maintenance requirements and enabling more compact machine designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contact type card reader is used to read magnetic stripe cards, then card data can be read, but the contact head is subject to excessive dirt accumulation and wear due to physical contact with cards
Solution Approach 1:
The patent replaces the mechanical contact-based magnetic stripe reader with a non-contact RFID reader that uses electromagnetic fields to read card data. This substitution eliminates the physical contact between the reader head and card, thereby preventing dirt accumulation and wear on the contact head while maintaining reliable card data reading capability.
2Adaptability or versatility
If a contact type card reader is used, then card data can be read, but the location and space required by the card reader can limit a machine from presenting additional banking features to a user
Solution Approach 1:
The patent implements an RFID reader that can read multiple types of cards (RFID cards, magnetic stripe cards, and contactless cards) using a single non-contact reading mechanism. This multi-functional capability allows the machine to present additional banking features while requiring less physical space compared to traditional contact-based card readers.
3Reliability
If magnetic stripe cards are used, then card data can be stored, but the cards are prone to wearing out and being duplicated
Solution Approach 1:
The patent replaces magnetic stripe cards with RFID cards that use contactless electromagnetic communication. This substitution eliminates the physical wear issues of magnetic stripes while incorporating security features such as encrypted data storage and authentication protocols that prevent card duplication, thereby improving both durability and security.
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 RFID card reader enhances security, reduces maintenance needs, and increases the functionality of automated banking machines by eliminating wear and dirt accumulation issues, while providing a more user-friendly experience and improved efficiency in transaction processing.
Implementation Method 1
A card reader is capable of reading user card data from a card without contacting the card with a reading device
Data Source
AI summary
An automated banking machine can receive user card data from a cell phone. The phone stores the card data of several selectable cards, including electronic account number data. The machine generates and displays a random number correlated with a time period. A machine user manually inputs the displayed random number into their phone. The phone's banking software application encrypts the selected card's data along with the inputted random number data. The phone displays a bar code image containing the encrypted data. The machine includes a bar code reader which can read the displayed image. The machine causes the read data to be decrypted. The random number is used to verify the current transaction session. Thereafter, normal transaction flow can follow, including PIN input. The process replaces physical insertion of a card yet allows secure input of the card's data. Fraudulent activities requiring card insertion are also reduced.
