List by: Neil 

• Sensors on boots and shin pads to determine accurately if contact is made with an opponent.
• All players must wear elbow length gloves with sensors to determine hand balls. 
• Swear Box: offending players must run to the touchline to get some money from their kit bag and then run to the other side of the pitch to deposit before being allowed to continue.
• A Star-trek style handheld medical diagnostic tool to instantly validate on-field injuries. 
• Electrodes that give attacking players a small but noticeable electric shock every time they drift offside.
