Reindeer herders in Finland's Lapland region are fitting their animals with Internet-connected collars to keep track of their whereabouts in the wilderness, using a mobile app.
The wireless collars, furnished by Finnish communications firm Digita, are designed to improve herding efficiency so herders can rely on fewer workers.
The technology also can help account for predation from wolverines, lynx, and other animals that migrate across the Russian border.
The collars use global positioning system satellite data and long-distance networks to help herders find dead reindeer in order to claim compensation from the government.
The Reindeer Herding Association's Matti Sarkela said his organization aims to shrink the transmitter down to a coin-sized microchip that can be affixed to a reindeer's ear.
