A data entry clerk is a member of staff employed to enter or update data into a computer system. Data are often entered into a computer 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. Proper ergonomics at the workstation is a common topic considered.
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 become very relevant as well; training on confidentiality protocols may be required, for instance, in the compliance of HIPAA. Beyond these traits, no technical knowledge is generally required and these jobs can even be worked from home.
