是否有指纹读取器 api/sdk? [英] Is there a fingerprint reader api/sdk?

问题描述

我需要从我的应用程序中读取用户的指纹.

I need to read the user's fingerprint from my application.

我真正想要的是一个简单的 SDK，它可以与许多廉价的指纹读取器配合使用，但如果该型号便宜且在全球范围内可用，我可以处理仅适用于一种特定型号的东西.

What I really want is a simple SDK that works with a lot of inexpensive fingerprint readers but I can deal with something that works only with one specific model if that model is cheap and available worldwide.

而且它必须是免版税的，我可以为开发许可付费，但如果我必须为每次安装付费，我就无法使用它.

And it has to be royalty-free, I can pay for a development license but if I have to pay for each installation I just can't use it.

我所做的与登录或加密无关，因此阅读器附带的软件可能对我毫无用处.

What I'm doing has no relation to login or encryption, so the software included with the reader will probably be useless to me.

推荐答案

据我所知，没有用于读取指纹数据的标准 API，因为它是一个相当新的领域，并且没有标准的方法.每个制造商都会提供自己的 API 来读取硬件.API 可能只是硬件的 IO 规范，没有任何库，这让事情变得有点棘手.这归结为两个因素.首先是指纹读取器用于许多应用程序 - 定制硬件、嵌入式系统到 PC 身份验证等等.从制造商的角度来看，为所有这些不同的系统提供软件是不可行的.其次，每个制造商使用不同的方法来读取和处理捕获的图像，这会导致通用 API 出现问题.

There is no standard API for reading fingerprint data as far as I'm aware since it is a fairly new field and there's no standard way of doing it. Each manufacturer will provide their own API for reading the hardware. The API could just be IO specification to the hardware and there's no library whatsoever, which makes things a bit trickier. This is down to two factors. The first is that finger print readers are used in many applications - custom hardware, embedded systems through to PC authentication and beyond. Providing software for all those different systems would not be viable from the manufacturers point of view. Secondly, each manufacturer uses a different approach to reading and processing the captured images which would make a common API problematic.
