Referee recorder for time tracking

Referee recorder is designed for professional referee use. In case
of a controversial moment during the match the referee presses a button and the device creates a time track. When the match finishes, the referee transfers the time tracks via NFC technology to the smartphone application. The referee is then able to go through only the selected time tracks instead of going through the entire match record.
