Ogaki Kyoritsu Bank in Japan is introducing ATMs to the market that authenticate a user with a hand-scan, birth date and PIN instead of a card. That way you can't use the excuse, "I forgot my bank card" when you don't have cash for dinner. Me? I always sneak out through the kitchen and pocket some dinner rolls on the way.
On top of being convenient, the machines are also a necessary response to the large number of ATM cards and personal IDs lost in last year's devastating earthquake.
