The "more4less" prototype has been delevoped in the information technology research project and gives a customer the possibility to get assistance in a buying decision process. By using the more4less terminal in a shop, in our case a fashion store, the customer has two main advantages at the decision procss: On the one hand the advisor suggests additive products to complete an outfit. On the other hand the customer gets a dynamic discount for the system usage and the buying of product bundles.
To inform the system about the product the customer ist currently interested in all products in the shop are equiped with optical 2d-barcodes. The advantage at this is that these 2d-barcodes can be printed by usual printers and thus they are particulary favorable und easy integratable in existing price marking systems. Furthermore 2d-barcodes can hold a much higher amount of information than only the product ID as in case of regular EAN-13 barcodes. Thereby on a voucher several product IDs, dealer information, affiliate information and the date of purchase can be encoded for later complaints or new consulting sessions using more4less.
When the system is being informed about a product or products a customer is interested in the customer gets additional product suggestions to complete the outfit evaluated by a especially for more4less developed price and bundle mechanism. A dynamically calculated total bundle price with discount is created as well. The prospective buyer can also hold multiple different bundle combinations and prices within the shopping cart by using the activate/deactive feature. In contrast to a regular shopping cart with this feature you can exclude products from price calculation without removing them from the cart.
To give the customer the possibility to freely move through the store during a advisory-session the customer gets a personal 2d-barcode printed by the system at the first contact with the system. With this 2d-barcode the customer can continue the advisory-session at every terminal inside a shop.
At the end of a shopping session the customer gets a voucher which also contains 2d-barcodes for each bought product and one tag which contains all products on the voucher. These barcodes enable the user to start a new advisory-session based on the product or products encoded in the 2d-barcode. The realisation of dynamic discounts based on already bough products or across different affiliated chains are conceivable as well.
The more4less prototype is based on Flash/Flex, Java, Castor, Axis2 and optical QR codes. The customer communicates with the system via a touch screen display. The 2d-barcodes are recognized via a typical webcam.
The following video shows the more4less prototype.
