"Why are we still dealing with physical cash at all? Credit/debit card infrastructure is thoroughly ubiquitous. I usually have a $20 bill or two in my pocket for emergencies, but I go months in between ATM visits to replace them. And judging by the silence whenever someone asks "Who has cash?" when it comes time to divvy up restaurant checks with my friends, I'm not alone in that attitude. The government would do well to start phasing out coins and paper money alike in favor of plastic cards that tie into a completely electronic system similar to how most of us prefer to handle our money anyway." - Eric P
