USA Today: Coke Sneaks Phones, GPS Chips Into Cans

This Summer, Coke will randomly place 120 GPS- and cell phone-equipped Coke cans throughout their North American distribution. Called the "Unexpected Summer," the sweepstakes hopes to build sales for the ailing Classic line.

Consumers who find one of the 120 cans can use the embedded phone to call and register for prizes such as a new Chevy Equinox SUV, a chance to win $1 million from Harrah's and Disney vacations. Once registered, Coke "search teams" will use GPS to find the individual and surprise them on a random day within a specified three-week period. Others can view the locations of the 120 cans on the promotional website.
