我被要求用“磁卡”开发带有 DB 的 ac#，从哪里开始？
我习惯使用前两个（c#，mssql），但我不知道磁卡是如何工作的。
它应该是一个USB设备，我想对磁卡进行一些调查，但我不能接受这个项目，然后意识到我做不到......
- 有人说他们没有任何类型的的 API 来处理它，c# 是否提供了一个？
- 我想每张磁卡都有某种加密，不是吗？如果真是这样，我就完蛋了。
- 怎样在卡上写字？ （写入的卡或数据是否保留在服务器上，并且该卡只保存一个 ID？）
- 您知道可以提供任何教程吗？
I'm used to work with the previous two (c#, mssql), but I don't know how does the magnetic card thing.
It's supposed to be an usb device and I suppose a little investigation concerning magnetic cards, but I can't accept the project and then realize I can't do it...
- I've been said that they don't have any kind of API to handle it, does c# provide one?
- I suppose that every magnetic card has some kind of encryption, doesn't it? If it does, I'm screwed.
- How to write IN the card? (Is the card that's written or the data stays on a server and the card only holds an Id?)
- Do you know of any tutorial you could provide?

我认为你应该回到潜在客户那里并询问更多细节 - 我猜这会比你想象的要小得多，并且向客户询问技术问题将有助于提高你的可信度。询问他们：
我曾经编码过的唯一“USB 磁卡”系统基本上工作如下USB 键盘输入 - 所以使用它只是使用文本框的情况。
I think you should go back to the potential customer and ask for a few more details - I'd guess that this will be much less stressful than you think it is and asking technical questions of the customer will help improve your credibility. Ask them:
The only "USB magnetic card" system I've ever coded against basically worked as a USB keyboard input - so using it was just a case of using a textbox.
首先了解该卡的更多详细信息。一旦您了解了类型和要求，您将能够提出更好的问题（更切题）并做出决定。
First get more details on the card. Once you know the type and requirements you'll be able to ask better questions (more to the point) and make a decision.
