Loyalty vouchers can be one type of deferred benefits granted to customers providing the conditions in the definition of the bonus buy promotion are fulfilled.
The voucher is printed on a fiscal printer immediately after the printout of a receipt. The validity period for vouchers is defined in each promotion (e.g. from the next day for 2 weeks). Each voucher has a unique bar code registered in the central vouchers server (i.e. central for the given store chain), which records both the issue of vouchers, as well as authorizes their use.
Vouchers can act as means of payment, entitlement to certain discounts, or they can also trigger subsequent promotions, e.g. they can allow for free reception of particular products, whereby it is possible to define the latter promotion so that receiving the item free of charge, requires collecting e.g. 5 vouchers.
