.NET Fingerprint SDK

c# .net fingerprint biometrics

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.

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.
