If the paywave terminals don't have a PIN pad (and for example the
ones they might fit to London underground gates probably wouldn't)
then they'll have to have a "plan B".
On the underground I would imagine its report to the ticket office, or
one of the ticket machines (which if my memory is right have a chip and
pin reader).

Everywhere I have seen paywave used (McDonalds is the most common, plus
have seen them in Wilkinsons) use the same terminal as chip and pin. At
a McDonalds drive through the cashier wont know if its chip and pin, or
paywave until after they have handed over the teminal.
