Heuston: Separate smartcard/ticket validation

[Kilocharlie]

Noticed this in Heuston recently. Some of the validation machines display 'Ticket only' and others 'Smartcard Only'.

The only problem is that this is not obvious until you reach a validator and look at the dimly lit display.

Good idea though to have smartcard only channels as smartcards are more efficient and give less problems than tickets.
