Wouldn't it be nice to forget your wallet - permanently? That day is coming sooner than you think. In the walletless future there will be no credit cards to lose, no cash to carry and no concert tickets to leave at home. Already, with a few taps on the screen of your smartphone, you can order a meal at a restaurant, loan your friend 20 bucks or even unlock the door to your house - so you can lose the keys, too.
