推荐答案

您不能使用来自手机指纹扫描仪的扫描指纹的原始数据.它们存储在硬件存储器中，无法进行提取和存储.您只能使用指纹扫描仪使用先前存储的指纹数据对用户进行身份验证.

You cannot use the raw data of scanned fingerprint from the mobile's fingerprint scanner. They are stored in the hardware memory and not accessible for extraction and storage. You can only use the fingerprint scanner to authenticate the user with previously stored fingerprint data.

如果需要提取指纹数据，则必须使用外部扫描仪设备.

If you need to extract the fingerprint data then you have to use external scanner devices.
