With the hype around cryptocurrency and ICO, we decided to create our own digital currency. The idea is to promote safe driving by promoting drunk driving. We believe the contradiction will help saves live. Drivers who are at a safe alcohol level, will earn our carkeytoken as an incentives. Drivers who are drunk will have carkeytoken remove from their account and their car key disabled from use. Their friends and family will also be contacted to rescue their love ones Drivers who have no alcohol level will not gain any carkeytoken Participants are able to convert their carkeytoken into actual currency depending on the value of the token at that time

As for the hardware, we are using arduino uno and HC-05 Bluetooth chip , the alcohol sensor and the finger tip heartbeat sensor will get the data then send in arduino to process.Then arduino will decide if the user is suitable for driving or not,and send the command and data through Bluetooth
