>> 1. Introduction

>> model for issuing and redeeming vouchers based on the Infrared
>> Financial Messaging (IrFM) architecture [IrFM]. A voucher is
>> a digital representation of the right to claim goods, service,

>> and vending machines, in the real world using local wireless
>> communication.
>> 
>> An important requirement of the voucher protocol is security.
>> A voucher is a financial instrument and several attacks, such as
>> voucher forgery, alteration, and duplicate redemption, need to be
>> considered for the creation and redemption transactions. It is
