What membership cards do you no longer carry because you have your iPhone?

I personally stopped carrying my BJ'S card, my AAA card, and library card. I use cardstar. Even replicates the bar code for the BJ's card and the library card so that I can scan the screen. I look forward to the day I can ditch my whole wallet and have all the info DL, credit cards and all on the phone. I have no worries of theft as I use a complex passcode.
 
Good idea

I like the idea but they need to come up with safety that someone loses a phone or hack/virus the mobile. I dont want to have a $2000 charges because of some bug.
 
It was only a matter of time...

And there was a Palm app that did invoice splitting with IR beaming over ten years ago. Again, prior artwork not paid attention to before they filed ... or intentionally ignored.
