While i think this social trick is clever, there are circles or perhaps industries where - as some other comments denote - recipients will not keep the cards; opting to simply enter the info into their phones, etc. However, i can definitely see in some other industries that are skewed more towards the social - such as but not limited to real estate, etc. - where this would work as a great ice breaker, or at least a method to keep some conversation continuing. Either way, I think this idea is pretty cool especially for how easy it is to do. Kudos to @matteoc!
