Linear

Set bars and spaces, readable in horizontal direction - barcode are vertically "redundand". This barcode category is older, but still used at most.

Advantages :

  • very easy print, can be printed on printers with small DPI
  • if barcode is damaged, no problem read encoded value visually in human part of image
  • for developers : easy programming, verys imple encoding algoritm, easy check digit calculation method

Disadvantages :

  • very small capacity - in practice max. to 20-30 encoded characters
  • not very high security - only one or two check digits, when barcode image contain some errors, can be unreadable
  • must contain quietzone around the barcode image
  • No error correction, only error detection

Examples :

Code 128
