Movie style door locl

Using Arduino Project Guidance
1

Hi,

I want to build a door lock for my room using an arduino. I want it to be like a lock from a film (I will try and post the name later if I can find it) where you swipe a card over a sensor, then type a password or scan a fingerprint or say a word. Would this be possible using an arduino?

I'm a newbie but here's what I think.

  1. Swiping card is possible with RFID.
    2)Typing password is also possible. Check out the keypad library.
    3)Finger print is also possible but expensive.(129$ from sparkfun Fingerprint Scanner - SEN-08839 - SparkFun Electronics
    4)Speech recognition too is possible.Is available as a shield from sparkfun. 50$ EasyVR 3 Plus Shield for Arduino - COM-15453 - SparkFun Electronics
    If I'm wrong correct me.

Hi,

I have been watching youtube videos and I know that each method can be done seperatly, but can it be done so that you need both a card and one of the other methods. Also could I make it that each card has a seperate password associated with it for like different people?

Yes, it's simply a matter of coding - don't open the lock until both things have been provided. If you have a really large number of cards to recognize, you might have to consider storing them outside the Arduino such as on as SD card, but most likely you won't approach such large numbers. Don't forget you can store the RFID and password data in progmem.
