摘要： A method of reading bar code symbols includes determining one or more parameters based upon the quantity and/or quality of the data which is being acquired, and providing the user with information concerning that parameter. The parameter may, for example, be the rate at which code words in the symbol are being read, and that information may be passed to the user by way of an LED which flashes at a rate which varies with the data acquisition rate. For a given bar code symbol being read, the rate of flashing varies with the position of the bar code reader with respect to the symbol. To improve the data acquisition rate, the user simply moves and/or rotates the bar code reader with respect to the symbol in a direction which causes the rate of flashing to increase. The invention extends to a bar code reader having means for providing an indication to a user of the relative suitability, for optimal reading of a symbol, of the current position of the reader.
