摘要： An arrangement for, and a method of, preventing a misread of a one-dimensional symbol that can be read in either one of two polarities in an electro-optical reader. A data capture assembly captures light from the symbol, and generates an electrical signal indicative of the captured light. A controller simultaneously processes and decodes the electrical signal as a first decoded result of one of the polarities and as a second decoded result of the other of the polarities. The controller also determines the validity of the first and second decoded results, and generates an output in dependence upon the validity determination.

摘要： A barcode reader for verifying a barcode is attached to an appropriate object particularly suitable for use at a point of sale. A database of expected object signatures in a vicinity of a properly affixed barcode properly is maintained. At a point of sale, the barcode reader obtains an image of a presented barcode (possibly not the correct barcode) and at least a portion of an object to which the presented barcode is affixed. Using data encoded on the presented barcode, the database is accessed to provide an expected signature of the object in the region of the presented barcode. A comparison is made between the expected signature of the object and a sensed signature derived from the image of the object. An improper barcode can thus possibly be identified and further investigation initiated.

摘要： A method of operating a laser scanner for reading a barcode. The laser scanner is configured to operate in at least two operating modes including a scanning mode and an aiming mode. The method includes operating the laser scanner in the scanning mode after a trigger signal is generated by a trigger on the laser scanner, and decoding the electrical signal that is received from the photodetector when the laser scanner is in the scanning mode. If the electrical signal from the photodetector is not successfully decoded after a first predetermined time period since the trigger signal is generated, alternating the laser scanner between the aiming mode and the scanning mode.
