The Class E α–male drone was specifically designed by Z-Tech to hover soundlessly over the countryside as an un-manned surveillance craft to guard against illegal alien entry and activities. Legal aliens, however, were judged to be good for the economy and welcomed with open arms and coupons for free drinks at the local taverns. This was primarily due to some undisclosed wild rave parties reputably held in Roswell, New Mexico during the 1940’s that government agents to this day still rarely talk about.
The big problem was determining the legality of an alien.
Z-Tech’s answer was to insert a rice-sized microchip into the legal alien’s arm. Because of its tiny size, it was practically undetectable once embedded. A polyethylene cover helped the chip bond with the skin to prevent migration.
The chip worked in much the same manner as the bar code scanner at your local grocery store. Only instead of a bar code, one has the half inch long microchip in your shoulder. When a scanner or reader passed over, a radio signal energized the dormant microchip which then transmitted a unique sixteen digit identification number. This number was used to provide access to a secure database in Switzerland containing the person’s complete medical history, bank records, and ability to have a good time.
So if the drone detected an unchipped alien…an unchipper one, it immediately zapped it with a laser which reminded it to lighten up and get a chip in it’s shoulder. If, after a reasonable period of time, the illegal alien still did not get a chip in it’s shoulder, the drone zapped the illegal alien with an even more compelling reminder to hurry things up a bit, as everyone knows foreigners with chips in their shoulders tell really good stories and do neat tricks that natives general haven’t thought about.
