This paper reports on tests of the performance of fingerprint recognition technology in rugged outdoor conditions, with an especial concentration on the performance in cold weather. The authors analyze: Chip versus optical fingerprint scanner technology, recognition performance and image quality, and user/device interaction. A outdoor fingerprint door access system was designed to capture fingerprint images and video data of user interactions. Using this device, data were captured over a period of two years, and a user survey performed. Data were analyzed in terms of biometric error rates and fingerprint quality (NFIQ) as a function of temperature and humidity.
