C# .NET 指纹 SDK

.NET Fingerprint SDK

提问by Kishore A

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)

我正在寻找可用于 .NET 的指纹读取器 SDK 的比较（我们使用的是 .Net 3.5）。我的要求是
1. 将多个指纹与一个人关联。
2. 自行存储指纹。（所以我不必为我的程序更改数据库。）
3. 在事件和无事件模式下工作。（事件模式：如果有人在阅读器上滑动手指，则发出通知；无事件模式：我以同步模式激活阅读器）。4. 应提供用于确认用户或识别用户的 API。（确认API：我发送此人的ID/唯一号码，它确认是同一个人；识别API：sdk使用指纹查找此人后发送此人的ID）

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

如果有人知道互联网上可用的指纹读取器，我还想对指纹读取器进行比较。

Hope I was clear.

希望我很清楚。

Thanks,
Kishore.

谢谢，
基肖尔。

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

我已经使用了 Queaso 的 SDK。SDK 支持您请求的功能。但您最好联系他们了解更多详情。

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

QFinger No longer exists just for an update.

QFinger 不再仅用于更新。

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

如果 QFinger 有点太多，请尝试 [ 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.

GrFinger 是一个非常简单的 SDK，不需要服务器等。您可以将它捕获的指纹存储为 byte[] 以您选择的任何形式。我们将它们作为 VARBINARY(MAX) 存储在 SQL Server 中，但您可以根据情况进行任何操作。

Since you are looking for a comparison of fingerprint reader SDKs, here is one you can start with. You can look up the BioPlugin SDKfrom M2SYS. This SDK allows developers to rapidly integrate multi-modal biometric software with any Windows or web software. It supports any SQL compliant database, including MS SQL Server, Access, MySQL, Oracle 9i, DB2, Informix etc.

由于您正在寻找指纹读取器 SDK 的比较，因此您可以从这里开始。您可以从 M2SYS查找BioPlugin SDK。该 SDK 允许开发人员将多模态生物识别软件与任何 Windows 或 Web 软件快速集成。它支持任何符合 SQL 标准的数据库，包括 MS SQL Server、Access、MySQL、Oracle 9i、DB2、Informix 等。

Since you also want to get a comparison of fingerprint scanners, Here are two I can recommend:

由于您还想比较指纹扫描仪，这里有两个我可以推荐：

1. The M2-EasyScan? USB Fingerprint Reader. The M2-EasyScan? fingerprint reader is a rugged, ergonomic fingerprint reader that ensures a consistent image quality and accurate results, even in high throughput environments.It captures a high quality image and will not degrade with frequent usage.

2. M2-EasyScan Pro?. This one is most suitable for both large scale or small scale fingerprint identification. It's thick, anti-scratch coating on the scanning surface endures long term heavy duty usage in any harsh environment without any difficulty. FBI certified to be compliant with PIV- 071006 image quality specifications for single fingerprint readers, the scanner is built to capture single fingerprint images from dry, moist, aged, scarred, and difficult to scan fingers for greater accuracy and reliability.

1. M2-EasyScan？USB 指纹读取器。M2-EasyScan？指纹读取器是一种坚固耐用、符合人体工程学的指纹读取器，即使在高吞吐量环境中也能确保一致的图像质量和准确的结果。它可以捕获高质量的图像，并且不会因频繁使用而降级。

2. M2-EasyScan Pro？。这个最适合大规模或小规模指纹识别。扫描表面有厚厚的防刮涂层，可在任何恶劣环境下长期重载使用，没有任何困难。FBI 认证符合 PIV-071006 单指纹读取器图像质量规范，该扫描仪旨在从干燥、潮湿、老化、有疤痕和难以扫描的手指中采集单个指纹图像，以提高准确性和可靠性。

You can also Google for fingerprint scanners and you will come up with a wide variety of options you can choose from.

您还可以谷歌搜索指纹扫描仪，您会提供多种可供选择的选项。
