POS Terminal Audio Playback for Continuous Operator Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During payment transactions at point-of-sale (POS) terminals, operators lack continuous auditory feedback, forcing them to maintain visual checks, and there is an untapped opportunity to utilize transaction time for delivering brand awareness or reinforcing brand identity.
Innovation Solution
Implementing a method and system where POS terminals detect interface events with payment cards, identify associated audio files, and play them between transaction commencement and termination, using audio playback devices to provide continuous feedback and promote brand awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If audio tones are played only as event alerts during payment transactions, then the POS terminal provides feedback for specific events, but the payor/terminal operator does not receive continuous audio feedback and must maintain visual check on the display
Solution Approach 1:
The patent applies continuity of useful action by playing audio tones continuously throughout the transaction period rather than only at discrete events. The audio feedback system maintains continuous operation from transaction initiation to completion, ensuring the operator always receives auditory updates about transaction status without needing to visually monitor the display.
Solution Approach 2:
The patent implements feedback by providing continuous audio tones that inform the operator of transaction status, progress, and completion. The system feeds real-time information about whether the transaction is ongoing, approved, or declined through auditory channels, eliminating the need for visual monitoring and improving operational ease.
2Ease of operation
If the POS terminal provides continuous audio feedback during the transaction period, then the operator does not need to maintain visual check on the display, but the system complexity increases
Solution Approach 1:
The patent applies universality by utilizing the existing audio playback capability of the POS terminal for multiple purposes: providing event alerts, delivering continuous transaction feedback, and potentially conveying brand information. This multi-functional use of the audio system avoids adding separate dedicated feedback hardware, thereby limiting the increase in device complexity while achieving continuous operator feedback.
3Adaptability or versatility
If the POS terminal utilizes transaction time for delivering brand awareness information, then the brand identity is reinforced, but the transaction feedback clarity may be compromised
Solution Approach 1:
The patent applies segmentation by dividing the audio feedback into distinct segments: transaction status information is conveyed through specific audio tones or patterns, while brand awareness information is delivered through separate audio content. This segmentation allows both transaction clarity and brand reinforcement to coexist without interfering with each other, as each type of information is transmitted through dedicated audio channels or temporal segments.

AI summary
The invention provides methods, point-of-sale (POS) terminals, and computer program products for delivering feedback through a POS terminal during a payment transaction involving a payment card. The invention comprises (i) detecting at the POS terminal an interface event comprising the payment card communicatively interfacing with the POS terminal, (ii) detecting at the POS terminal, a payment application stored within a memory of the payment card, (iii) identifying an audio file associated with the detected payment application, and (iv) initiating playback of the identified audio file through an audio playback device controlled by the POS terminal, wherein playback of the audio file is implemented between a playback commencement event detected by the POS terminal and a playback termination event detected by the POS terminal.
