I'm working on a web app using JavaScript and PHP. I need to integerate DigitalPersona fingerprint reader into the app. I have downloaded One Touch SDK and it includes activeX control and a nice UI demo in VB.net. I want to call the activeX control with javascript whenever the user clicks a button and have it send fingerprint images to a php code but I don't how to go about it. I have done some research on how to do that and I glimpsed that I have to include an object tag with a classId in the html codes.

Unfortunately, I don't know what classid to use nor which of the DigitalPersona package to call. If it's possible to call the VB demo that would be awesome.

Please anyone with experience on how achieve this? I would be eternally greatful for your help.

StackOverflow would be your best bet. Nairaland programmers hardly help sadly.

I have equally done that yet no result

JavaScript and PHP? Using their java applet is more simpler, as it will commutate with JS or the PHP.

I once saw a tutorial on stack sometimes ago

Did you know only IE supports ActiveX control? And did you know you might need to enable some stuffs on the IE to use it?

Here are 2 suggestions for you,

- Using ActiveX + another app that captures biometrics + Ajax
Here you could implement the sdk with a desktop app, then launch the app from within IE using ActiveX of course, after launching you want to keep making ajax call to your server to check for a column in your db, this column would be modified by the biometrics app after enrollment by making a request to a URL, once a change has been detected from the web, you want to redirect your user to the necessary page. Quite rough right?

- Using another biometrics app + Ajax
For this one, you want to simply ignore the ActiveX part, and when it gets to where biometrics capture is needed, you launch app manually, and then keep making ajax requests behind the scene.

Meanwhile, I'm not saying calling your sdk isn't possible, I'm just providing alternatives.

bonne chance
