I've been asked to develop a c# with DB with a "magnetic card", Where to start? [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

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?

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:

• do they have any kind of system overview document
• have they selected the magnetic card (reader?) to use
• what sort of things are they expecting to store

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.

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.
