Tensor's HSCAN3000 hand scanner terminal employs red and green indicator lights in order to clearly notify the user of a positive or negative match. Plus, it grants fast and easy access to a series of very useful features, such as Edit-at-the-Clock Functions and Bell Schedules, which enable employers to set the day, time, and duration of a series of bells that can be programmed to signal the beginning or end of a shift, lunch, or break.
