Design an access control system using finger scan. Stored finger scan database is on remote server, the system should be control access: by raising alarm on multiple failure opening door on successful match. For the above design.
i) Develop and draw functional model using FSM.
ii) Develop and draw block diagram representing hardware modules/blocks.
iii) Suggest list of components with proper justification for the selection (from several options available)
