WS-Biometric Devices allows desktops, laptops, e-tablets and smartphones to access sensors that capture biometric data using web services. Current biometrics systems generally have proprietary, device-specific drivers and cables, making it more cumbersome to interconnect devices. Web services don’t require knowledge of proprietary facial, iris and fingerprint scanners, which could frustrate those trying to connect them to computers that perform biometric analysis. With web services, biometric scanners and devices providing the analysis don’t have to be at the same location because they’re linked wirelessly.”]
