The brilliant invention of bar code resulted in an amazing advantage due to its 3 advantages of reading speed, accuracy, and superior functionality characteristics. This method of coding dominated the market and the demand for codes capable of storing more information, more character types, and that could be printed in a smaller space increased. The developers involved in various efforts to increase the amount of information stored by bar codes, such as increasing the number of bar code digits or layout multiple bar codes in that little space.
