Mobile phone shopping makes wallets redundant in Japan

Japanese office worker Satoshi Tada pays for shopping, wins free food and gets store discounts all by waving his cell phone.”I use it pretty much every day,” the 25-year-old said. “You can charge money on it right there if needed, and you don’t have to run around trying to find an ATM. You can even get points because it’s linked to credit cards.”
