PINpad Integrated Camera Scanner Independent Security Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In transaction processing, the handling of customer identification cards by cashiers and storage of their information on insecure terminals pose security risks, as this increases the chances of identity theft and fraud.
Innovation Solution
A PINpad with an integrated scanner/camera and independent security processing capabilities, allowing it to capture and decode images, establish a network connection independently of the host terminal, and interact with external servers for verification without sharing decoded information with the terminal, thereby eliminating the need for physical handling of cards and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal includes attached peripheral devices and processes transactions on the terminal, then transaction processing capability is improved, but security risk increases due to handling of customer identification information
Solution Approach 1:
The system is divided into separate functional components: the host terminal handles transaction processing while the PINpad device handles identification verification. This segmentation allows the terminal to maintain productivity while the PINpad independently manages sensitive identification data, reducing security risks associated with centralized handling.
Solution Approach 2:
The PINpad device acts as an intermediary between the customer's identification and the host terminal. It captures images, decodes information, and communicates verification results to the terminal without exposing raw identification data to the terminal or cashier, thus reducing security risks while maintaining transaction processing capability.
2Reliability
If the driver's license is scanned and stored on the terminal, then verification capability is improved, but vulnerability to electronic theft increases
Solution Approach 1:
The sensitive identification data processing function is extracted from the host terminal and placed in the PINpad device. The terminal only receives verification results rather than raw identification data, extracting the security risk from the terminal while maintaining verification capability through the PINpad's independent processing.
Solution Approach 2:
Instead of storing and transmitting raw identification data, the system uses image capture and decoding to create processed verification data. The PINpad captures an image of the identification, decodes it locally, and transmits only the verification result to the terminal, reducing vulnerability to electronic theft while maintaining verification reliability.
3Reliability
If the cashier physically handles the identification card, then in-person verification is achieved, but risk of identity theft increases
Solution Approach 1:
The mechanical handling of physical identification cards by cashiers is replaced with an automated image capture and decoding system. The PINpad device uses its camera to capture images and decode information automatically, eliminating the need for cashiers to physically handle cards while maintaining in-person verification through the integrated camera and decoding capabilities.

AI summary
A peripheral PINpad is connected to a host terminal. The PINpad includes an integrated camera/scanner, a secure processor, secure storage, and a network interface. The PINpad is configured to process in an independent mode of operation and a host-dependent mode of operation. Images captured by the integrated camera/scanner are decoded on the PINpad. The decoded image information, depending on a processing context, is not provided to and is not available to the host terminal. The PINpad is further configured to perform network interactions with external servers independent of the host terminal.
