A system for providing voucher dispensing and redeeming using current mobile communications hardware and infrastructure. The system enables the creation, reception and usage of voice vouchers, wherein digital vouchers are embodied as attachments within voicemail messages. In this way, the system enables the transfer and interaction with online vouchers using existing voicemail systems, such that the content and authentication data of a voucher may be received and redeemed using a standard mobile communications device. Furthermore the voucher may be verified and controlled by a voucher vendor, by using a specialized voucher server.
