The purpose of this study is to create a set of best practices to capture fingerprints using an Crossmatch L-scan Guardian ten-print device. A program was used to capture user errors due to placement of fingers on the platen. User error results were analyzed based on data obtained from the created program, during user interaction. Based on the results of this research we were able to create a set of user-friendly best practices to assist in Crossmatch L-scan Guardian ten-print scanning.
