Touchless Access Control System Using Biometric and Thermal Screening

The system enables individuals to automatically verify their own health status through self-service kiosks that capture temperature readings and health questionnaire responses without requiring manual verification by security personnel. The individual's biometric data and health information are automatically processed and compared against established guidelines, eliminating the time-consuming manual verification process while maintaining reliable health guideline compliance.

Manual verification processes are replaced with automated electronic systems including thermal imaging cameras for temperature detection, biometric scanners for identity verification, and computerized health questionnaire systems. This substitution of mechanical/manual processes with electronic automation reduces entry time while ensuring consistent application of health guidelines without human error or oversight.

The access control system is designed as a multi-functional integrated platform that combines biometric authentication, thermal imaging for temperature detection, health questionnaire processing, and access authorization in a single unified system. This universal system handles multiple screening functions simultaneously, improving productivity by processing all health-check parameters in one automated workflow rather than requiring separate systems for each function.

The system employs a nested architecture where multiple functional modules (biometric scanner, thermal camera, questionnaire interface, decision-making algorithms) are integrated within a hierarchical structure. Each module operates semi-independently but is coordinated by a central control system, allowing the complex system to be managed through modular components while achieving high screening efficiency through their coordinated operation.

Physical contact-based verification methods are replaced with non-contact technologies including thermal imaging cameras that measure temperature from a distance, biometric scanners that capture facial or retinal patterns without contact, and wireless communication systems for data transmission. These touchless technologies maintain verification accuracy by using advanced sensors and algorithms while eliminating the infection transmission risk associated with physical contact.

The system introduces intermediate technologies such as thermal radiation detection and optical field interaction as mediators between the verification system and the individual. Instead of direct physical contact, the system uses these intermediary physical fields to capture biometric and health data, ensuring both touchless operation and high measurement precision through sophisticated sensor technology and data processing algorithms.
