GSM Magnetic card door lock

we are interested in creating the best secure door lock(house doors, secure safe), the lock and unlock features will be performed by using magnetic card and memorable 6 digit pin sent to the server as sms(encrypted) for authentication

so we should use miniature magnetic card reader(why miniature because we are looking to create ultra small compact magnetic card reader) and normal keypad with numeric keys for password entry

and encryption and decryption part should be simple and secure

the battery should be used in a optimum way
