Smartcard Wireless Access Authorization Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smartcards lack a transceiver unit for wireless communication and a memory unit for secure access authorization, compromising security and convenience, especially in access-restricted locations.
Innovation Solution
A smartcard system with a substrate integrating a transceiver unit for signal transmission and reception, a memory unit for storing indicative identification data, a display unit for authorized information, and a battery unit for power, where the authorization client accesses complementary information for identity verification, ensuring high security and convenience through wireless communication and localized recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional smartcards are used without a transceiver unit, then the device structure is simpler, but wireless communication capability for access authorization is lost
Solution Approach 1:
The patent combines the transceiver unit, memory unit, display unit, and battery unit into a single integrated smartcard device. This merging of previously separate components into one unified card enables wireless communication capability while managing device complexity through integration rather than separation.
2Reliability
If user information is stored on the smartcard, then access authorization is faster, but security level is reduced because information can be stolen if the card is lost
Solution Approach 1:
The patent extracts sensitive user information (name, photograph, company data) from the smartcard and stores it only in the authorization client's database. The smartcard retains only a unique identification number. This extraction of sensitive data from the card eliminates the security risk of card loss while maintaining authorization functionality through the distributed architecture.
Solution Approach 2:
The authorization client acts as an intermediary between the smartcard and the access control system. It receives the identification number from the card, looks up the corresponding user information in its database, and processes authorization. This intermediary approach allows fast authorization without storing sensitive data on the card.
3Ease of operation
If the smartcard displays user information, then user identification is clearer, but security is compromised as information can be read by unauthorized persons
Solution Approach 1:
Instead of displaying user information on the card face, the patent inverts the approach by having the card display only a generic message like 'Authorized User' or 'Access Granted'. The actual identifying information is obtained through wireless communication with the authorization client, which is only accessible to authorized users in the authorized area.
4Adaptability or versatility
If a transceiver unit and memory unit are added to the smartcard, then access authorization functionality is improved, but the device becomes more complex
Solution Approach 1:
The smartcard is designed as a multi-functional device integrating wireless communication (transceiver), data storage (memory), display capabilities, and power supply (battery). This universal design enables multiple functions including identification, authorization, and information display within a single device, managing complexity through consolidation.
