Things to note:
You must pay a membership fee ($30)
If paying by credit card you must pay a surcharge (at least $20)
You must be registered (i.e. no anonymity)
You cannot transfer the card to anyone else
If you're lucky enough to know your job is safe for 12 months (and not moving house/offices to change your travel routine), and don't mind the government being able to track your travel patterns, it's a good saving given that we're being shafted yet again at well-above inflation rates for a sub-standard public transport system.
