How many travel passes can I have? A Snapper card has five “slots” inside it where passes are stored. Two of the slots are reserved for storing bus passes, two are designed for rail passes, and one is reserved for a Metlink Explorer day pass. Slots 1 & 2 – bus passes The first slot stores your active bus pass: this is the pass you are currently using to travel on a particular bus service. You can only have one active bus pass at a time. The second slot on your Snapper card stores an inactive bus pass. When you use up your active pass it gets deleted off your Snapper card and your remaining pass moves up into the active slot, leaving the second slot free again. NOTE: If you have both of the two bus pass slots full and try to buy a third bus pass you will be notified that you have already reached the maximum bus pass limit. You will need to wait until your active bus pass either expires or runs out of trips before you can buy an additional pass. Slots 3 & 4 – rail passes The third and fourth slots are designed to store rail passes. Like bus, you have have two rail passes stored – one that is active, and one queued up to use when the first expires. Slot 5 – Metlink Explorer day passes Slot 5 is reserved for a Metlink Explorer day pass. You can only have one of these stored on your card at any given time.
