Or bank card payments (which is what I tend to use to top up my Oyster 
card at LU stations).

Or register the card on the web site and pay through that, either to 
automatically collect the tokens onto your card at a gate at an LU 
station of your choice, or else by authorising an auto top-up (again 
actioned at an LU station gate) by bank debit when your card balance 
falls below a threshold.
