提问by user2028555
I want to build an androidapplication like employee attendance using fingerprintscanner. I want to know that,
我想android使用fingerprintscanner. 我想知道，
- Is it possible using external hardware device for fingerprint scanning?
- How to integrate Android application with external hardware finger print scanning device.
- How to fetch data from external hardware device and store data in local database.
- 是否可以使用外部硬件设备进行指纹扫描？
- 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将数据存储在本地数据库中。
Thank you in advance.
先感谢您。

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:
是的，有一些指纹扫描仪与 Android 平台和 Android SDK 兼容。扫描仪插入 USB 端口，因此您无法同时为平板电脑充电和使用指纹扫描仪。例如：

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.
还有一些设备带有集成指纹扫描仪和 SDK，用于注册和验证多个用户。例如三星或 iPhone 只提供 SDK 来验证 1 个用户（设备的用户），而其他制造商提供 SDK 来注册和匹配多个用户。

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