Abstract
A system and method for issuing electronic vouchers representing value. An issuing server generates an eVoucher that a recipient may use to purchase goods and services from a merchant's e-commerce Web site. The eVoucher includes an image, such as a corporate logo, that identifies the issuing merchant. Nonimage data, such as a unique identifier for the eVoucher and encrypted arbitrary text, is embedded in the eVoucher image and is used to track the use of the eVoucher and to verify its authenticity.
