Brazil's school system has come up with a way to deter students from cutting class, but it's raising a few eyebrows. Every student is required to wear a uniform loaded with a microchip. As students pass through the school's entrance a sensor sends their parents a text alerting them their son or daughter has arrived.
It also lets the district know if kids are skipping their classes. If kids miss class three times and the parents refuse to explain the absences school officials will notify the local authorities.
