Abstract

A method of issuing electronic vouchers (Vi) which a user (U) may submit to a merchant (M) in exchange for goods or services comprises the steps of: an issuer (I) receiving an electronic declaration (Di−1) from the user (U), the issuer verifying the electronic declaration (Di−1), and the issuer issuing a new electronic voucher (Vi) for use with the merchant (M) only if the electronic declaration comprises a signature (SM) of a merchant on a previous electronic voucher (Vi−1). The vouchers (Vi) and declarations (Di−1) are preferably blinded by the user such that the user remains anonymous. However, the electronic vouchers (Vi) may contain the identity (Q) of the user (U), which identity may be revealed when a voucher is submitted more than once.
