A data entry clerk, similar to a typist, is a member of staff employed to enter or update data into a computer system database, often from paper documents using a keyboard, optical scanner, or data recorder. The keyboards used can often have specialist keys and multiple colors to help in the task and speed up the work. While requisite skills can vary depending on the nature of the data being entered, few specialized skills are usually required, aside from touch typing proficiency with adequate speed and accuracy. The ability to focus for lengthy periods is necessary to eliminate or at least reduce errors. When dealing with sensitive or private information such as medical, financial or military records, a person's character and discretion becomes very relevant as well. Beyond these traits, no technical knowledge is generally required and these jobs can even be worked from home.
