According to (Waarden,2008 )¹, he specified the impact of the loyalty program membership on customer purchase behavior is considerable and worthy. The behavior indicator represents that members and non-members have major differences in the purchase behavior . The purchasing power of cardholders in term of many factors such as total and average shopping baskets, the share of purchases, purchase frequency and inter‐purchase time is much more than the non-members throughout entire three‐year period and business areas.
The researchers are also trying to describe and discuss the methods of virtual membership system and the method of reading the cards. The method for providing virtual membership cards for the cardholder is through the creation of virtual membership cards that is based on the information of the cardholder and card issuer , then send the virtual membership card to the mobile terminal of the users through a communication network. The virtual membership cards consist of membership management module that manage card issuer and users account information. The membership cards make the dealer easily issue, validate and maintain their membership cards and for the users can easily restore, use and manage their membership card at any place and at any time. The virtual membership card reading method contains the scanning of the virtual membership card that will appear on the transportable terminal which is provided by a card broker, to change it into a digital signal and then decoding and decrypting the digital signal to obtain information of a card issuer and the card user information.
