Swipe Card Project

Thank you so much for all the help everyone has given me so far, its greatly appreciated. Its a broad area to research so anyone with any other relevant information feel free to pitch in! P

Very small images, like 1x1 or 2x2 pixels might be possible.

You could also hide some programs, nada comes to mind

Any ideas as to how i would go about doing that? Anything no matter how small is useful.
