hey everyone i'm new to arduino just bought my first starter kit and is anxious for it to be shipped.
I want to create something like a PIN Machine for a POS System. I want to create an arduino device that will allow the user to enter a numeric code and this code will be passed to the POS system via usb or wireless. The system will then do the additional processing basically I want to be able to pass data between the device and the POS system. Also what are the options available for custom housings for the device is there a website or someone who i can contact and they can design a housing for this device I am thinking of creating.
I'm new so any tips, cautions, recommendations and/or code will be greatly appreciated :)
