Teenagers in London are being given special "smart" cards which pay out rewards if they are well behaved.
The cards, part of a new £1million police project called the "Karrot" scheme, are fitted with clever microchips which store points awarded for good behaviour, like:
- Going to school
- Behaving well
- Showing good citizenship
The 11 to 15 year olds collect points which are then exchanged for fun things like tickets for football and basketball matches as well as theatre shows.
Well-behaved teens will also get free time in special mobile internet cafes with 12 speedy computers.
Police hope the Karrot scheme will cut down on the amount of money spent on dealing with and preventing teenage crime, like truancy and anti-social behaviour.
They also think it'll encourage young people to be "good citizens".
