外部硬件指纹扫描仪和Android设备集成 [英] External Hardware Fingerprint scanner and android device integration

问题描述

我想使用指纹 扫描仪构建一个 android 应用程序，例如员工出勤率。我想知道，

1. 是否可以使用外部硬件设备进行指纹
   扫描？


2. 如何将Android应用程序与外部硬件手指集成
   打印扫描设备。


3. 如何从外部硬件设备获取数据并将数据存储在本地数据库中。

提前谢谢。

解决方案

1. 是否可以使用外部硬件设备进行指纹扫描？

是的，有一些指纹扫描仪兼容Android平台和Android版SDK。扫描仪插在USB端口上，因此您无法同时为平板电脑充电并使用指纹扫描仪。例如：

• http://www.futronic-tech.com/product_fs80h.html


• http://www.crossmatch.com/authentication-hardware/

还有一些设备带有集成指纹扫描仪和SDK，可以注册和验证多个用户。例如，三星或iPhone仅提供SDK来验证1个用户（设备用户），但其他制造商提供SDK来注册和匹配多个用户。

如何将Android应用程序与外部硬件指纹扫描设备集成。

如何从外部硬件设备获取数据并存储数据本地数据库。

指纹扫描仪（上面引用）有Android SDK注册和验证。有些仅返回指纹图像。对于指纹扫描仪只返回图像，您必须使用外部库将图像转换为细节，并注册并验证为：

I want to build an android application like employee attendance using fingerprint scanner. I want to know that,

1. Is it possible using external hardware device for fingerprint scanning?
2. How to integrate Android application with external hardware finger print scanning device.
3. How to fetch data from external hardware device and store data in local database.

Thank you in advance.

解决方案

1. Is it possible using external hardware device for fingerprint scanning?

Yes there's some fingerprint scanners compatible with Android Platform and with SDK for Android. Scanners are plugged on USB port so you can't charge tablet and use fingerprint scanner simultaneous. For instance:

• http://www.dermalog.com/en/products_solutions/fingerprintscanner/
• http://www.futronic-tech.com/product_fs80h.html
• http://www.crossmatch.com/authentication-hardware/

There's also some devices with integrated fingerprint scanner and with SDK to enroll and verify multiple users. For instance Samsung or iPhone only provide SDK to verify 1 user (user of device) but others manufacturers provide an SDK to enroll and match multiple users.

2. How to integrate Android application with external hardware finger print scanning device.
3. How to fetch data from external hardware device and store data in local database.

Fingerprint scanners (quoted upper) have Android SDK to enroll and to verify. Some of ones only return fingerprint image. For fingerprint scanners only return image, you have to use external library to convert image to minutiae and enroll and verify as:
