<p>A data processing system (1) and a method are disclosed for provision of rewards such as mobile telephone air time to customers. A transaction means (11) comprises a database (111) at the checkout which stores product data for a plurality of products for purchase. A second database (112) stores offer data representing a value (monetary or otherwise) of an offer relating to those products. A till (113) receives information on the products purchased and forwards it to a first data processor (114) where a total cost is calculated. This is combined with data from the database (112) at a second data processor (115) to produce a total offer amount. This is concatenated or otherwise combined with a live code (120) to produce an encrypted rebate code (119) that includes a representation of the rebate amount. This is printed onto a till receipt (118). A mobile telephone user sends the printed rebate code to an operator (211) at a clearing house location (21). Once the rebate code (119) is validated, the user's mobile telephone account may be credited with airtime in accordance with the value as included within the rebate code (119).</p> |
