Abstract
Successive products associated with targets to be electro-optically read are swiped or presented, in their respective turns, to a window in a point-of-transaction workstation. A proximity system detects entry of each product into a zone outside the window. The products are distinguished from one another in response to detection by the proximity system of the exit of each product from the zone, preferably by sensing a change in magnitude over time of return infrared light returned by each product.
