.NET Fingerprint SDK

Question

I am looking for a comparison of Fingerprint reader SDKs available for .NET (we are using .Net 3.5). My requirements are
1. Associate more than one fingerprint with a person.
2. Store the fingerprints it self. (So I do not have to change the Database for my program.)
3. Work in both event and no-event mode. (Event Mode: Give notification if someone swipes a finger on the reader; No-Event mode: I activate the reader in synchronous mode). 4. Should provide API for either confirming a user or Identifying a user. (Confirm API: I send the person's ID/unique number and it confirms that it is the same person; Identifying API: The sdk sends the person's ID after it looks up the person using the fingerprint)

I would also like to get a comparison of Fingerprint readers if anybody knows of one available on the internet.

Hope I was clear.

Thanks,
Kishore.

Answer 2

I already worked with the SDK from Queaso. There SDK support the features that you request. But you better contact them for more details.

The product is called QFinger. You can also find there a list of readers...

Answer 3

If QFinger is a little too much, try [http://www.grfinger.com/].

GrFinger is a pretty simple SDK that requires no server, etc. You can store the fingerprint it captures as a byte[] in however form you choose. We stored them as VARBINARY(MAX) in SQL Server, but you can do whatever your situation calls for.
