This device displays 18 sets of 5 different (non repeating) number combinations using the numbers 1 though 18.  The numbers appear in windows labeled "E I P E I".

Is this a genuine authentication device or is it a toy?  Can anyone identify the manufacturer, country of origin, the meaning of EIPEI and why the use of numbers 1 through 18 versus any other sequence?
