As with many new technology advances in the finance sector, I predict this to be use for crime. Right now it's easy for criminals to get money into paypal accounts, but difficult to get money in their hands, because it often requires steps that involve tying a transaction to a bank account or something traceable. If someone can just walk into a store and type a couple of numbers into a keypad and walk out with items worth cash, it gives the criminals an easy gateway to spend their ill-gotten funds.
