Biometrics logon

It depends on the device.   In general, each provides it's own API for talking to the device(s).  Either that or they output a text file that you can read.

  In one app I wrote many years ago, we used Ingersol Rand's  Handpunch reader (it scanned the outline of your hand) as input to a time clock application.

  If you indicate the device you wish to use, I can provide a little more guidance.

Many thanks for your response, Jim, I wish to deploy on a desktop computer running with Windows 7/10.

But what kind of device?   Hand reader, Iris scanner, finger print or palm scanner, etc.  Need to know what and the Mfg and Model number

 That drives what you need to in Access.  There is no "one size fits all" approach in Access (or any product) to dealing with a biometric device.

Jim.

A finger print scanner is more preferred.

You have to tell me which one and I can give you some more direction.  

 As I have said, each is different.   Different manufactures use different methods, and sometimes even different models from the same manufacturer will as well.

 Some might use a USB driver, others a COM Object, while with others it might be an API that you need to call in a DLL they supply.  With others it might have a device read and write files, and some you might need to talk to through TCP/IP.  Some might even use a database that you read/write to or use ODBC to read/write to your database directly.

 I will add that in general, I have never found a device yet that I cannot talk to using Access and VBA.   But what form that will take I cannot tell you until you specifically say what it is you plan to use.

Jim.

Thank you for the insight Sir,
I will go ahead to get a specific device, but wouldn't mind if you will suggest one that you think would work best for the purpose I described, after which I'll them share the specifications with you and we'll move ahead from there.
Thanks for your support.

Thanks a lot, Jim. Your comments has been immensely helpful!
