Do image quality and minutiae count differ between sensors? Does price have an impact? Is there interoperability between sensors? With regards to biometric technology, interoperability is very important. “Sensor interoperability refers to the ability of a biometric system to adapt to the raw data obtained from a variety of sensors” (Jain, 2004). Ideally, sensors from different manufacturers and differing systems should be able to communicate with each other successfully. However, it is possible that there could be a significant difference in image quality and minutiae count between different sensors, sensor technology types, manufacturers, and price ranges. This study was conducted in order to determine and evaluate the impact of differing sensors and sensor technologies on image quality and minutiae count. This study investigated whether nine different fingerprint sensors were interoperable. Seven of these sensors were optical and two were capacitive. 165 fingerprint images (all right index fingers) from 55 subjects were recorded. The study showed that there was a significant difference between sensors in both fingerprint image quality F(8, 1475) = 5.05, p = 0.000, and minutiae count F(8, 1475) = 34.434, p = 0.000.
