Some time ago MacLitigator showed you how to use your iPhone for flash cards. Now, a genius in the blogosphere shows us how to use your iPhone to replace all those ‘club cards.’ In short, scan your membership card (local bar, federal bar, Costco, gym membership etc.) and save them as photos in iPhoto. Create a folder that syncs with your iPhone (call the folder ‘wallet’ or ‘wallet cards’) and automagically you get all your cards in one convenient location. And, best of all, the bar codes can be read and scanned. Of course, this technique can also be used as an alternative to MacLitigator’s technique of emailing yourself a set of evidence flash cards.
