You should contact the Customer Service Centre on 0345 6000 650 as soon as you realise your smartcard is missing. The card will be disabled and a new one issued; this can take up to 7 days.
Any paper tickets purchased in between are not refundable as we are unable to deduct them from the Touch Smartcard. Any unused Flexi Season ticket day passes may be refunded before they expire.
A growing number of our stations can also help you with a lost smartcard. Click here for the full list.
