Before long, those tall, green, coin counting machines you see in supermarkets will be dispensing prepaid MasterCards. Coinstar, DataWave, and Michigan National Bank announced this week they have teamed to issue a MasterCard branded prepaid card through the Coinstar and DataWave networks. Coinstar owns and operates the only nationwide network of supermarket-based machines that offer coin counting and other electronic services. The Company estimates there is $7.7 billion in coins sitting in people's homes. The approximate value of a coin stash is between $30-$50 per U.S. household. Since last summer, Coinstar and Canada-based DataWave have worked together to integrate DataWave's wireless processing technology into the Coinstar network of machines to sell prepaid phone cards. Coinstar owns and operates the only nationwide network of supermarket-based machines that offer coin counting and other electronic services. This week's announcement will move Coinstar beyond offering just coin counting machines. Eventually this new technology will give Coinstar customers the option of turning their coins into a convenient and secure prepaid MasterCard. For more information visit http//www.coinstar.com.
