M-Voucher is a mobile based loyalty based program.  M-Voucher has checks the multiple parameters.

M-Vouchers are special offers delivered directly to the consumer’s mobile phone via SMS by for instance say a Retail Store. It can be sent to your mobile phone regardless of what carrier you are connected to, or whether you use prepaid or a postpaid. A mobile Voucher with / without barcode will hold all the information that the sender wants to send to the subscriber’s mobile. This code can then be redeemed at the point of sale, at the store. M-voucher could be used for
Promotions, sales, discounts, and thus, in turn increasing their revenues.

Similar to the M-Ticketing, M-voucher will help in reducing the cost, time, effort, etc and also helps in increased redemption rates as they are stored on the phone itself and therefore cannot be lost or misplaced. This can also be used to Loyalty programs. First time the barcode is sent discounts would be less, while the second time (after it is redeemed), it would be increased, and so on. This makes a consumer, loyal to the store.
