A novel cost effective access control and auto filling form system using QR code

QR codes are used to store information in two dimensional grids which can be decoded quickly. The proposed work here deals with Quick response (QR) code extending its encoding and decoding implementation to design a new articulated user authentication and access control mechanism. The work also proposes a new simultaneous registration system for offices and organizations. The proposed system retrieves the candidate's information from their QR identification code and transfers the data to the digital application form, along with granting authentication to authorized QR image from the database. The system can improve the quality of service and thus it can increase the productivity of any organization.
