where do you get an at hop card
AT HOP card Cards may be "topped-up" or monthly passes purchased in the following ways: online, at ticket machines, at ticketing offices, and at selected retail outlets such as bookshops. Top ups may be made by credit or debit card, with the latter three mediums accepting cash payment. The card is designed to reduce the number of transactions at ticket offices and the number of paper tickets. Usage is encouraged by offering cheaper fares than the cash ticket option, although there is an initial once-only fee to purchase the card. Monthly and/or multiple trip travel is only available with the AT HOP card.
Card security code The card security code is typically the last three or four digits printed, not embossed like the card number, on the signature strip on the back of the card. On American Express cards, the card security code is the four digits printed (not embossed) on the front towards the right. The card security code is not encoded on the magnetic stripe but is printed flat.
