QuickScan Calculator (QSC) has been proposed in this paper. QSC is a highlighter shaped electronic calculator equipped with Optical Character Recognition (OCR) technology. It generates results instantaneously when an arithmetic expression is scanned by the QSC. Therefore, people can perform calculations without the process of "punching buttons". This would help the people to reduce the error made when wrong buttons are punched. Technical implementation concerns, societal concerns and possible future developments have been fully addressed in this positioning paper.
