Wireless Smart Card Reader Multi-Device Session Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart card readers are typically dedicated to a single computing or mobile device due to their reliance on dedicated connections like USB or wireless links, limiting their use with multiple devices without severing existing connections.
Innovation Solution
A smart card reader system that enables secure pairing with multiple communication devices through unique identifiers, security values, and master connection keys, allowing simultaneous wireless communication and secure data transmission across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart card reader uses a dedicated connection (USB or wireless link) with a single device, then secure data transmission is ensured, but the reader cannot be used with multiple devices simultaneously
Solution Approach 1:
The patent segments the connection management by creating separate, isolated connection contexts for each device. Each device receives a unique identifier and establishes its own dedicated communication channel through the reader, allowing multiple devices to be served simultaneously without interference. The reader maintains separate session states for each device, enabling independent authentication and data transmission processes.
Solution Approach 2:
The smart card reader is designed to perform multiple functions by supporting connections with different device types (mobile phones, tablets, computers) through a single unified interface. The reader can simultaneously handle wireless connections from multiple devices while maintaining secure authentication protocols, making it a universal access point for various computing and mobile devices without requiring device-specific hardware.
2Reliability
If a smart card reader establishes a dedicated wireless connection with one device, then secure authentication is maintained, but switching to another device requires severing the existing connection
Solution Approach 1:
The system performs preliminary authentication and establishes secure connection parameters for each device before actual data transmission begins. Each device undergoes independent authentication processes, and secure communication channels are pre-configured with unique identifiers and encryption parameters. This preliminary setup ensures that when devices switch, the authentication security is already in place and can be quickly transitioned without compromising security protocols.
3Adaptability or versatility
If multiple devices connect to a smart card reader simultaneously, then multi-device support is achieved, but connection security and data isolation become challenging
Solution Approach 1:
The patent implements local quality by providing each device connection with its own unique security parameters, including device-specific identifiers, individual authentication credentials, and isolated data transmission channels. Each device-session combination has customized security settings that ensure data confidentiality and integrity specific to that device, preventing cross-device security vulnerabilities while maintaining overall system security.

AI summary
A system and method is provided for managing multiple smart card sessions with multiple communications or computing devices in association with a single smart card reader. A wireless smart card reader is provided for communicating with a plurality of devices requiring smart card functionality in a number of smart card sessions, in which each smart card session is addressed with an identifier identifying a single device. The smart card session is secured by a wireless connection pairing and by a secure pairing, such that each connection between the smart card reader and a device is secured against all other devices in communication with the smart card reader using a master connection key, which is unique for each device.
