A data entry operator is a member of staff who reads hand-written or printed records and types them into a computer. They are sometimes employed on a temporary basis, but most large companies which have large amounts of data will hire on a near-permanent basis. For a mailing company, data entry clerks might be required to type in reference numbers for items of mail which had failed to reach their destination, so that the relevant addresses could be deleted from the database used to send the mail out. If the company was compiling a database from addresses handwritten on a questionnaire, the person typing those in would be a data entry clerk. In a cash office a data entry clerk might be required to type expenses into a database using numerical codes. The number of data entry clerks is declining as it becomes easier for people in other positions to enter data as it emerges.
