Self-service terminal RFID validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-service terminals, such as ATMs, face challenges in efficiently validating the authenticity of deposited media items in real-time and have costly and unreliable depository modules due to electromechanical and imaging components.
Innovation Solution
Incorporating a wireless tag reader into the self-service terminal to read RFID tags embedded in media items, allowing for simultaneous validation of multiple items without physical separation, and using a tamper detection circuit to render defaced items valueless.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electromechanical depository modules are used to validate media items, then validation can be performed, but the device complexity and cost increase due to electromechanical and imaging components
Solution Approach 1:
The patent replaces electromechanical validation components with a wireless tag reading system. The media acceptor is simplified to primarily mechanical functions (accepting and holding media), while validation is performed electronically through wireless communication with RFID tags embedded in or attached to media items. This substitution eliminates complex electromechanical validation mechanisms while maintaining or improving validation reliability.
2Reliability
If traditional depository modules with imaging components are used, then media validation is possible, but the cost and reliability worsen due to component failures
Solution Approach 1:
The invention replaces expensive and failure-prone imaging components with wireless tag reading technology. The system accepts media items through a simplified mechanical interface and validates them by reading wireless tags (RFID) that are either embedded in the media or attached to them. This approach significantly reduces manufacturing costs while improving reliability, as wireless tag readers have no moving parts and require minimal maintenance.
3Reliability
If media items are processed singly through traditional depository modules, then validation is thorough, but the productivity decreases due to time-consuming processing
Solution Approach 1:
The patent enables continuous processing of multiple media items simultaneously. The media acceptor can hold and process multiple items at once, and the wireless tag reader can read multiple tags in rapid succession or simultaneously. This eliminates the need to process items one at a time while maintaining thorough validation, as each item's wireless tag is independently verified. The system validates all items in the stack before dispensing, ensuring comprehensive checking without sacrificing speed.

AI summary
A self-service terminal for reading wireless tags incorporated into media items is described. The terminal comprises a media acceptor for receiving media items, such as banknotes incorporating an RFID tag, and a wireless tag reader for reading received media items incorporating wireless tags. The terminal may also include a wireless tag reader for reading wireless tags in media items that are being transported to determine if multiple superimposed media items are present. The terminal may include a wireless tag reader for reading wireless tags in media items presented as a bunch, and subsequently retracted, to determine if any of the presented media items had been removed.
