How The Key Smartcard works

Travelling in and out of London? The Key Smartcard can save you time and hassle. It’s a smartcard that you use to touch in and out at the ticket barrier. You load tickets onto it – so there’s no need to stand in a queue. And The Key is free: there’s no deposit and you don’t need to pay anything over the normal price of your ticket.
