Bezel Tongue Integrating NFC Module for ATM Data Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transactional devices, such as bill validators, lack the ability to receive additional data types like wireless transactional data and biometric information, and current solutions are either cumbersome or require significant modifications to the device's cabinet, complicating the integration of wireless communication functionality and biometric sensors.
Innovation Solution
A bezel assembly with a wireless communication module and biometric sensors, such as fingerprint or finger vein readers, integrated into a forward-extending hollow tongue that projects from the bezel housing, allowing for intuitive data input and improved wireless connectivity without requiring extensive modifications to the transactional device cabinet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication functionality is added to legacy transactional devices by modifying the cabinet, then data reception capability is improved, but device complexity and modification cost increase
Solution Approach 1:
The bezel is divided into a stationary portion attached to the cabinet and a movable tongue portion that can be independently positioned. This segmentation allows the wireless communication module to be integrated into the movable tongue without requiring modifications to the cabinet structure, thus improving adaptability while maintaining simplicity.
Solution Approach 2:
The bezel assembly is designed to perform multiple functions: it serves as both the traditional bill insertion interface and a wireless communication interface. The movable tongue can be positioned to accommodate different data input methods (physical insertion or wireless communication), making the device versatile without requiring separate systems for each function.
2Device complexity
If wireless communication module is placed inside the cabinet, then device complexity is reduced, but wireless transmission efficiency decreases due to cabinet thickness and material
Solution Approach 1:
The wireless communication module is positioned in a different spatial dimension by extending the movable tongue forward from the cabinet. This allows the antenna to be located outside the cabinet's metal structure, improving wireless transmission efficiency while keeping the module integrated with the bezel assembly rather than requiring separate cabinet modifications.
3Adaptability or versatility
If a second payment location is added separate from the bill validator, then wireless reception capability is improved, but ease of operation decreases as consumers cannot determine where to initiate transactions
Solution Approach 1:
The wireless communication functionality is merged with the existing bezel assembly rather than being placed in a separate location. The movable tongue integrates both the physical insertion slot and the wireless communication interface into a single user-facing element, providing a unified and intuitive interface that maintains ease of operation while adding wireless capability.
4Device complexity
If chip & PIN card reader is placed in a vertical wall, then device complexity is reduced, but ease of operation worsens as it does not intuitively indicate where consumers should position their mobile phones
Solution Approach 1:
The movable tongue provides a distinct, localized area with specific physical characteristics (forward extension, defined surface) that intuitively indicates where consumers should position their mobile devices. This localized design improves ease of operation by creating a natural focal point for interaction, while the overall structure remains relatively simple.

AI summary
A bezel assembly for data reception is provided for use in a transactional device that comprises a door attached to open and close. The bezel assembly comprises: a casing secured to the door, an interior insertion/dispensing slot formed in the casing, a hollow tongue or protrusion forward-extending from the casing to define a bottom surface of the interior insertion/dispensing slot, and a wireless communication module arranged in the hollow tongue or protrusion for communication with a built-in NFC chip in an identification card when put in the interior insertion/dispensing slot to identify a user of the identification card.
