"Green Taxi" - follow this cab

London invented pink cabs for the ladies by the ladies ? Seoul replies with its Green Taxis. Don't expect any environmental friendly gimmick : GTs are about removing the fear factor from the cab experience.
It's late and you're alone in the dark. Enter Travis Bickle with his mohawk (a.k.a. Robert de Niro in Scorcese's Taxi Driver). Friend or foe ? You decide to take the chance, but to play it safe you RFIDly download his ID (license plate) on your cell phone. Tadaa : your family knows who's taking care of you and where you are.
And Travis knows he's being watched. He also knows you don't trust him.

The Green Taxi concept ? A frustrated psycho killer driving a paranoid customer.

I prefer another killer application : 3,500 to 5,000 Korean cabs will accept credit cards, including seamless payments with your mobile phone.
