Why has stored-value not caught on?

Why have general-purpose stored-value cards been unsuccessful in penetrating the U.S. market? Three necessary conditions for a payment instrument to be successful are discussed: consumers and merchants need to be convinced of its advantages over existing payment alternatives for at least some types of transactions; payment providers must convince consumers and merchants simultaneously of its benefits to achieve critical mass; and assure them that adequate safety and security measures have been implemented. This article discusses the credit card industry’s success in meeting these necessary conditions and general-purpose stored-value issuers’ failure to meet them to date.
