“…In that context, several key indicators have been analysed in the literature that influence the level of benefits customers expect from using loyalty cards, such as: 1) price discounts (Leenheer et al, 2007) imply that cardholders receive a discount on the value spent during purchase; 2) more efficient service and rewards allow holders of loyalty cards faster service on special cash registers, rewards in the form of gifts for a certain number of points collected (purchase), etc. ; 3) personalized communication (Mercadé-Melé, Molinillo, Fernández-Morales, & Porcu, 2018; aims to strengthen the relationship between the seller and the customer based on personal address and correspondence; 4) payment option (Lovreta et al, 2010) refers to certain forms of non-cash payments available to card users; 5) better information (Reinartz, 2010) implies that loyalty card users receive timely information about discounts, special offers, new products and services, etc. ; 6) status symbols (Huberman, Loch, & ÖNçüler, 2004) are intangible benefits related to the psychological feeling of satisfaction and reputation in an environment created by the possession of certain loyalty card (e.g., Gold cards offered by some supermarkets) and 7) additional benefits (Kyguoliene et al, 2017) that may be hedonistic and social, but also specific additional benefits such as cards used for purchases abroad, etc.…”
