Using cellphones as cash

November 22, 2007 on 2:38 pm | In Cell phones | 2 Comments

A dozen major European companies in November have opened the largest trial outside of Asia for the use of cellphones as mobile money – giving consumers the ability to pay for everything from croissants and toothpaste to subway fare and wine with a wave of a handset. And they have global aspirations, hoping to prove that their systems, using the short-range radio technology called near field communications – NFC, can work securely on a mass scale.

Cellphones could start masquerading more widely as bank debit cards a year from now – assuming the manufacturers can get the right handsets to market and the players can agree on how to divide the revenue, two issues that have tripped up the mobile industry in the past.

The experience in Asia, where the Sony technology called FeliCa has already turned the cellphone into a contactless mobile wallet, is something of a model for Europe.

Then you have to switch to a new card,” said Augusto Revolorio, a Miami Beach grocery stocker. “It costs me more to complain on the phone and be late for work, so I just rip up the calling card and buy a new one.”

Some phone cards fail to deliver the promised minutes. Others tack on confusing fees that may not be listed in the microscopic print on the back of the card. Still others rounding up each call to the nearest three-minute mark.

In the past year, attorneys general in Florida, California and several other states have begun to take a closer look at the calling card industry, as has the Federal Trade Commission.
