    Question Car Start on Finger-Print Recognition?

    Would it be possible to do this?

    Either 1) Wire a Finger-Print scanner to the pc, so it only boots if a fingerprint is picked up, then start the car, via a line out(LTP?) to a relay, would mean PC would be on before Car PC

    Or 2) Wire the scanner to the relay for starting the car directly, then the PC boots like normal

    In the first case you'd need a button to start the car, but in the second one it'd just start when the print was recognised.

    These sites may be helpful, Print-Readers or Bio-link U-Match

    Edit: I also just found this, which may be of some use, considiring it dosent need the PC to be on

    Try searching the forums with terms "fingerprint". There's a big thread on the MS fingerprint reader there.

    problem with going straight from the scanner to ignition is that you would have to have a dedicated system. one idea is that there are scanners for home doors that controll relays to unlock the door. you may try something like that and just run the relay connection to the ignition. personnaly id just run straight through a computer with biometric login and a startup program signaling relays through one of its ports.

    Ok, I wrote a program to put on the CPU of the UniFingerô SFM3000.

    Its written in BASICA or GW-BASIC which is the only code I know off by heart, here it is, please point out any mistakes

    Code:
     10 if in5<>1 and in4=1 let x=1 else let x=0
     20 in in1=1 and x=1 let y=1
     30 if v=1 let y=1
     40 if x=0 let y=0
     50 let v=0
     60 gosub 170
     65 if in3=1 and in2=1 let y=0
     70 if y=1 and in2=1 goto 90
     80 goto 10
     90 let y=2
    100 let v=1
    110 for w = 1 to 50
    120 if in3=1 goto 10
    130 next w
    140 gosub 170
    150 let y=1
    160 goto 10
    170 if y=0 let out1=1 else let out1=0
    180 if y=1 let out2=1 else let out2=1
    190 if y=2 let out3=1 else let out3=1
    200 return
    Here are the varibales and inputs I'm using (you can use 8, which i have 5 in, 3 out, though out1 is probabally unnecissary)

    Code:
    in1	Thumbprint Match signal
    in2	On/Off PTM stitch
    in3	Engine running sensor
    in4	Drivers Door PTM (Closed gives value of 1)
    in5	Alarm Indicator singal (1 is alarm on)
    out1	Off
    out2	On/Drive
    out3	Ingition
    v	Remember ignition position from loop
    w	loop
    x	Door and alarm OK
    y	Key state
    The line ins or outs may have to be linked to relays or optoisolators

    actually, you can bypass the fingerprint biometrics with a gummybear.

    It would be proably be best to use an aftermarket car remote start system. There is more to starting most cars then just the ignition wire. Many remote starts can be activated with a neg pulse and that would cover all the relays, safety shut offs, starting and stopping the car.

    gummybear? ill have to try that out sometime.

    and yeah, you should keep spare thumbs in your wallet, just in case you leave yours inside your car.
