A system for reading indicia such as bar code symbols having a scanner for generating a scanning light beam directed toward a symbol to be read. A trigger manually displaceable from a first position to a second position produces a first light beam for aiming or positioning the reader.The trigger is automatically returnable, or held in the second position, or manually displaceable from the second position to the first position for initiating a scanning beam pattern for reading the symbol. A detector receives the reflected light from the symbol and produces electrical signals corresponding to data represented by the symbol.

A hand-held bar code reader, in particular a bar code wand is used by a consumer to read bar code information accompanying a product displayed at a retail outlet. The bar code information can be presented in, for example, UPC format and carries information relating to the products. The consumer subsequently down-loads information stored in the reader via a suitable interface to a personal computer which accesses information identified by a address included in or comprising the bar code information. The site contains additional information such as price information concerning the advertised product and the consumer may be able to pay for and order the product directly via the site. As a result the consumer has a simple reminder of the product, is able to obtain additional information concerning the product with minimum difficulty and can obtain the product itself with maximum ease.

An electrical interface for a scan engine includes a plurality of control pins including a range limiter mode pin, laser enable and scan enable pins, a signal output pin and a start-of scan indicator pin. Operation of the scan engine can thus be controlled to reduce power consumption and laser on-time as desired.
