Jostens debuts NFC-enabled class rings for school champions

Jostens, the jeweler best known for making Super Bowl championship rings, introduced a line of class rings that interact with smartphones. The Champ DX Championship Ring is embedded with  near-field communications (NFC) chip to preserve video and photo highlights of a sports team's winning season. The digital content in the ring can be accessed through a free mobile app that Jostens created with jewelry maker Galatea. Jostens piloted the technology last year with the Valley Christian High School Warriors football team from San Jose, California.
