It's made of a thin, flexible membrane material with an adhesive backing (just remove the paper) so you can attach it to nearly anything. This keypad has 12 buttons, arranged in a telephone-line 3x4 grid. The keys are connected into a matrix, so you only need 7 microcontroller pins (3-columns and 4-rows) to scan through the pad.
