The best part about that keyboard is the credit card swiping slot along the top If only you could get it to work to pay for on-line goods while sitting at home at your computer
The credit card's
magnetic stripe stores the credit card number, expiration date and CVC number.
Once you have reverse-engineered the card reader, it would be easy to just make it emit the credit card number.
Making it fill in the different fields on the web form automatically would be a bit more difficult...
You could perhaps have an application in the background that detects card swipes and pops up a window with the fields; then allowing you to drag and drop the different numbers from that window to the relevant text fields.
OP I hope you do know what POS stands for before you opened this thread?....
I think he knows more than
one meaning of the acronym.
