SHIZUO KAMBAYASHI / AP By putting NTT DoCoMo's new P506iC wallet cellphone next to an Edy card machine, customers can pay for a variety of purchases with a flick of their handset.

Japan has long been phasing out the hassle of coins and bills with microchip-laden "smart cards," which let people make electronic payments for everything from lunch to the daily commute.

But even smart cards could be on their way out, their plastic presence overtaken by virtual-wallet technology now available in the everyday cellphone.

Other nations, led by South Korea, already have so-called mobile commerce payment schemes in place that let people punch keys on their cellphones so that the devices trigger transactions. But a series of phones going on sale this summer in Japan, for use on NTT DoCoMo's wireless network, are the world's first with an embedded computer chip that you can fill up with electronic cash.

The wireless company loaned me a P506iC handset from Matsushita Electric Industrial and I was in business. Well, almost.

First I had to find a machine that's used to stoke smart cards with cash. They can be found in some convenience stores and offices in Japan. You place the phone in a special spot in the machine and slip bills into it. The phones have a 50,000 yen ($450) limit.

Now you can spend.

To pay, you simply wave your cellphone within a few inches of a special display found in stores, restaurants and vending machines around Japan. A fairylike tinkling sound means your purchase is being deducted from the embedded chip using radio-frequency ID technology.

It's instantaneous, and rather fun to pay for things this way.

It's also an idea that makes sense, given that almost every Japanese has a cellphone and relies on it for so much information that being stranded in the street without one almost causes panic. There are 81.5 million cellphones in this nation of 127 million people.

For the wallet phone tech to really take off, stores, theaters and restaurants that accept electronic payments need to become more widespread. They total around 9,000 in Japan so far, but the number is quickly growing.
 
To buy a diet Pepsi from a vending machine, I pushed a button on the machine that indicates electronic payment and pushed another button to pick the soda. When a display the size of a small greeting card lit up with the price, I put my phone next to the display.

Shazam. The soda pop rolled out, and the display blinked with the amount of money left in the phone.

To pay for my fried-rice lunch at a restaurant in our office building, I brought my bill to the register and told the clerk I wanted to pay electronically. When he rang it up, the little display lit up with the price at the counter. I just flashed my phone.

Like millions of other Japanese, I have a few smart cards. One, the Suica, works as my commuter-train pass. The other, an Edy card, works as a wallet at some stores, and its "cash" machines are the ones NTT DoCoMo uses for its phones.

I carry my Suica practically every day. But I don't always remember my Edy. So the P506iC wallet phone was handy, indeed. After all, what reporter is without a cellphone these days?

Computer experts have suggested that hackers could develop a way to pickpocket cellphone wallets merely by getting close to people's handsets. That hasn't happened yet.

Another concern is that a telecom company — or a government — could find out too much about your spending proclivities and your physical movements.

But other features on Japan's richly endowed cellphones offer marketers plenty of information on consuming habits as it is: Almost all phones have e-mail and Internet connections for restaurant searches, ringtone downloads, news and weather.

The P506iC, like most new mobile-phone models, has a digital camera and color display. Oh, and it takes 15-second video clips and has a memory-card slot.

One Japanese airline lets passengers use the phone to speed up check-ins at airports, and next year you'll be able to use the phones to pay for train rides and video rentals.

Later this year, Japanese credit-card company JCB plans to offer a service that will let corporate clients use chip-embedded phones as electronic keys to get into office buildings.

And if you lose your digital wallet phone?

Well, DoCoMo can lock it. Which means no one else can use it for calls. And no one else would be able to add more money to the cash-dispensing chip.

But whatever money is stored on the phone is like a virtual wad of cash. The clerk at the DoCoMo store repeatedly told me not to put any more money into the phone than I could afford to lose.
