Purchase or build a biometric input device.

Interface it to the microcontroller.

Interface the microcontroller to an electrically-controllable door lock.

Write a program for the controller to read the device's input and compare it to the stored "correct" value, releasing the lock when they match. Allow for reasonable amounts of measurement error, with the understanding that the more forgiving you are, the less secure you are -- but also understanding that no device provides perfectly repeatable results.

You do not worry about money, how much money you need to answer the question?
