LevelUp is a smartphone app. in which you can link your credit or debit card and pay by putting your phone up in front of a special scanner at the cashier stand. Not only do you get amazing discounts from this app, but your receipts are e-mailed to you! NO PAPER INVOLVED! Think about how much paper and ink can be saved if this becomes the norm! Plus, many local businesses already have LevelUp readers at locations throughout Boston - its a great (not to mention convenient) way to support local businesses.
