Using cellphones as cash
November 22, 2007 on 2:38 pm | In Cell phones | 2 CommentsA 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.
But despite more 30 million wallet phones in circulation, success there may be overrated: As with other mobile technologies, Vestergaard said, the Japanese and South Korean markets are “special cases,” with dominant players and closed markets.
