A system that uses an essentially stationary device to scan barcodes or the like associated with items such as retail goods and services, library books, and so on. The system further includes an interactive graphical user interface that enables consumers to obtain a wealth of information about the scanned items and items similar in kind and/or different in kind but related in purpose to the scanned items, as well as promotional events and selling opportunities associated with the scanned items. The system allows a consumer to involve social knowledge in the decision making process of borrowing or purchasing a particular item. In an instant, the consumer can get a sense of an item's benefit to him or her based on the publicly available opinions of others. The system may be used to instantly check out items, communicate with staff, function as digital signage or to locate items in a facility.
