I am excellent in data entry work. I can work without fear & do the job anywhere. Data is often entered into a computer system from paper documents using a keyboard. For a mailing company, data entry clerks might be required to type in reference number for items of mail which had failed to reach their destination. So that the relevant address 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 into the database would be a data entry work
