How can I implement the point of sales in an application

[mondi]

Hello everybody!
In an application I have to make possible for the customers to pay using the point of sales. But I do not have any idea how to make the program interact with the point of sales. I want from the program to check for the validation of the card and to get the money from the point of sales.
Maybe I am completely wrong with my definitions, but if any of you has any samples or any ideas how I might make it work in the application would help me a lot.
Thanks in advance for any help!

This is something that has been done so often that there are downloadable libraries to help you with this. I would do a Google, as well as check on sites like download.com and sourceforge.

Also: Check out some of the manufacturer's websites. A lot of POS companies will post a development section with a full API.

I couldn't find something that could help me to better understand the way how the POS can be integrated in a C# application. I would like to have any samples on that, how to make the customer pay by visa card or master card, how the program can find the drivers for the POS, or something like that. I am completely out in this field and something that could open my mind would be really useful to me.
Thanks for your answers however

What POS Machine are you interfacing with? What company/model.

In terms of design - I would recommend creating some sort of driver class, that extends a custom interface.

Actually the application is intended to be a product, so I don't know what POS Machine will be. But if you could give me any example or anything just to see how an application can interact with the POS Machine. I don't know when putting the card in the POS machine, how can I get the amount of money that are in the card and how can I make the application get the money from the card after putting the number of the card and the PIN. I see even myself that I am completely out in this field, and maybe the things I am saying may sound nonsense.
Thanks
