Touchscreen Customer Display Signature Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional point of sale (POS) systems require an additional signature pad for customers to sign, which increases costs and complexity.
Innovation Solution
A POS system that includes a POS terminal and a customer display with a touchscreen and processing module, which controls the touchscreen to display a signing area, detect touch points, generate detecting signals, and transmit signature data to the POS terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an additional signature pad is connected to the POS terminal to acquire customer signatures, then the signature acquisition function is achieved, but the device complexity and cost increase
Solution Approach 1:
The patent merges the signature pad functionality into the existing touchscreen display by utilizing the touchscreen's capacitive sensing capability. The processing module detects touch points on the touchscreen surface and generates detecting signals that are processed into signature data, eliminating the need for a separate signature pad device while maintaining the signature acquisition function.
Solution Approach 2:
The touchscreen display is designed to serve multiple functions: it displays transaction information and simultaneously functions as a signature pad by detecting touch points through its capacitive sensing layer. This multi-functionality is achieved through the processing module's ability to distinguish between different touch interactions (screen tapping vs. signature writing) and process them accordingly.
2Ease of operation
If an additional signature pad is connected to the POS terminal to acquire customer signatures, then the signature acquisition function is achieved, but the cost increases
Solution Approach 1:
The patent combines the signature pad functionality with the existing touchscreen display components. The capacitive sensing layer and processing module that already exist in the touchscreen are utilized to detect signature inputs, eliminating the need to purchase and install a separate signature pad hardware component.
Solution Approach 2:
The touchscreen display serves itself by using its own capacitive sensing capability to detect and process signature inputs. The processing module within the touchscreen system handles the detection, signal generation, and signature data creation without requiring external signature pad hardware.

AI summary
A point of sale (POS) system for acquiring a signature of a customer, includes a POS terminal and a customer display. The customer display includes a touchscreen, and a processing module that is electrically connected to the touchscreen and the POS terminal. The processing module is configured to control the touchscreen to display a signing area during a signature acquisition procedure, and control the touchscreen to allow the customer to perform a signing operation on the signing area. The processing module is further configured to control the touchscreen to detect touch points on the touchscreen and to generate multiple detecting signals that are related respectively to the touch points as the signing operation is being performed on the signing area of the touchscreen. The processing module is further configured to generate signature data based on the detecting signals, and to transmit the signature data to the POS terminal.
