RIchard Taylor reports for the BBC on the growth in the use in Japan of mobile phones as wallets.

In a society where two out of three people own a mobile, and there is always one eye on the future, they have figured: why not take things one step further?

Yes, it is time to say sayonara to your wallet.

John Boyd writes for the IEEE Spectrum Online about NTT DoCoMo's mobile payments activities in Japan.

The critical element in DoCoMo's Osaifu-Keitai, or mobile wallet, is a wireless smart card chip, FeliCa (from the English word "felicity"), which was developed by Sony Corp. and Royal Philips Electronics for close proximity, low-data-rate transactions. The wallet phones can be used to make electronic purchases at stores or vending machines equipped with FeliCa readers; can act as boarding passes on certain domestic air flights; and can authorize entry through corporate security doors—all with a wave of the handset.

Zhu Shenshen reports for the Shanghai Daily on action by the People's Bank of China to impose limits on online payment amounts in an effort to manage the potential risk.
