Hirokide Osaku, manager of the sixth floor of the flagship Kinokuniya bookstore in Tokyo's Shinjuku district, doesn't like the new point-of-sale reader from mobile network operator NTT DoCoMo, which allows his customers to tap their phones to make credit purchases. He's had to make room for it on his counter and train his employees to use it. Just the same, he sees why Kinokuniya, Japan's largest bookstore chain, has rolled out new readers along with all new point-of-sale terminals at its 50 branches to accept DoCoMo's new"iD" credit brand. "We didn't want other bookstores to get an advantage," he says. "Probably, in a few years, iD will be popular, so it's important to have it first."
