Here's how you use your genie once you've topped it up:
If you've not got enough cash on your card for the journey you're making, you'll need to top it up again before buying your ticket.
If you ever need to check your card balance, ask the driver to inspect the card. They can tell you how much cash you have remaining.
Any cash on your card can only be used for single, return and day tickets. It can't be used to buy a week or four week ticket.
Here's how to use your genie that has a valid pass on:
It's that simple!
Towards the expiry date the machine will tell you that you need to buy another pass.
You can buy another pass before the existing one runs out as it's tagged on the one you currently have. So, if you have 2 days left and you add another week, you'll have 9 days travel remaining on your genie.
If you ever need to check the expiry date of your pass, ask the driver to inspect the card. They can tell you how many days you have remaining.
