POINT-OF-SALE DISPLAY SYSTEM

摘要

A computer-implemented method for data display is provided, which includes receiving a request for a product from a customer (42A) in a first line (40) at a retail location having multiple adjacent customer lines (40, 44). An advertisement is selected responsively to the requested product, and is displayed on a customer-facing electronic display (28) positioned at a second line (44), which is in proximity to the first line. Other embodiments are also described.
