A new service has been launched in the US allowing users to purchase ringtones, graphics and mobile games with a pre-paid DuoCash card. The �micro-payment� solution removes the need for an online credit card transaction. Instead, web purchases are made with DuoCash enabled phone cards that are available at thousands of retail locations across the USA.

The service will be offered to Toneguys' visitors. It's a very smart move, as Todd McKay, managing director of Toneguys explains, given the fact that a large percentage of the mobile content market is comprised of teenagers who do not have their own credit cards.
There might have been a simpler and faster solution... premium rate messages... but the adoption in the US is going really slow.
