- Inspector Jacob Foucault: The Grid takes all those things unique to you, your social security number, your passport, your debit and credit accounts and links them to one thing... your DNA. With just a touch, the Grid collects a tiny sample of your genetic material, ID-ing you instantly. Then a purchase can be deducted directly from your personal accounts, or you can unlock and start your car and it all works within a margin error of 0.001%... the ultimate social network!
