With the new system it could just 'track' you and know, but what about before when it was all tolkens?The fareboxes on the trolleys are used for payment at above-ground stops and regular gates are used when underground. If you get on above ground and get off underground, you can transfer as normal. If you get off above ground, just tap your card once you get on another trolley (though above-ground GL transfers are rare) and the system will recognize the transfer and not charge you anything.
