Retail Barcodes

  1. 1. Retail Bar Coding Basics a Tutorial
  2. 2. Is bar coding necessary? <ul><li>Reasons for UPC bar codes. </li></ul><ul><li>Want to sell your products via retail stores. </li></ul><ul><li>Products are sold at checkout counters. </li></ul><ul><li>Product is a food item or consumer retail item. </li></ul><ul><li>Reasons UPC bar codes not necessary </li></ul><ul><li>Bar codes are only for internal use such as inventory </li></ul><ul><li>Products are not sold via retail stores. </li></ul><ul><li>Products are not sold at checkout counters </li></ul>
  3. 3. History of Retail Bar Codes <ul><li>1932 Wallace first to suggest automated checkout </li></ul><ul><li>1948 Drexel University begins research into auto ID method </li></ul><ul><li>1949 Woodland & Silver build prototype scanner. </li></ul><ul><li>1952 Patent granted Woodland & Silver for Auto ID method </li></ul><ul><li>1966 First commercial use of bar codes </li></ul><ul><li>1970 First commercial Auto ID product </li></ul><ul><li>1972 Kroger stores begin using ‘bulls-eye’ bar code </li></ul><ul><li>1973 Uniform Product Code standard adopted </li></ul><ul><li>1974 First UPC scanners commercially marketed </li></ul><ul><li>1974 First product (Wrigley Gum) UPC bar coded. </li></ul>
  4. 4. What is a Bar Code? <ul><li>A bar code (barcode) is similar to “Morse Code” in that they both encode character information. </li></ul><ul><li>Morse Code was developed in 1935 and consists of s code based on short and long electrical impulses. </li></ul>  7 units of time   pause between words   3 units of time   pause between letters   3 units of time   dah   1 unit of time dit

  7. 7. What is a Bar Code? Check Character Calculation (UPC) In this example, the check digit is 7. 100 - 93 = 7. Step 6: Subtract from the next higher multiple of 10. 72 + 21 = 93 Step 5: Add the result of Step 2 with the result of Step 4. 1 + 5 + 9 + 1 + 5 = 21 Step 4: Sum all the digits in the even (E) positions. 24 * 3 = 72 Step 3: Multiply the result by 3 3 + 4 + 7 + 0 + 2 + 8 = 24 Step 2: Sum all the digits in the odd (o) positions O E O E O E O E O E O 3 1 4 5 7 9 0 1 2 5 8 Step 1: Designate the least significant digit position as odd.
  8. 8. How a Bar Code Works <ul><li>Light from the scanner (laser, LED, or other) reflects off the label back to a sensor in the scanner </li></ul>
  9. 9. Bar Code Symbologies <ul><li>The manner in which the bars and spaces are encoded define the bar code symbology </li></ul><ul><li>Codabar </li></ul><ul><li>Code 128 </li></ul><ul><li>Code 3 of 0 </li></ul><ul><li>Code 93 </li></ul><ul><li>EAN 13 </li></ul><ul><li>EAN 8 </li></ul><ul><li>ISBN </li></ul><ul><li>Interleaved 2 of 5 </li></ul><ul><li>MSI / Plessey </li></ul><ul><li>Postal / Postnet </li></ul><ul><li>UPC A </li></ul><ul><li>UPC E </li></ul><ul><li>PDF-417 </li></ul>
  10. 10. Global Trade Identification Numbers <ul><li>A GTIN (Global Trade Item Number) is the EAN.UCC System identifier used for the unique identification of trade items worldwide within the EAN.UCC System. </li></ul>Trade Items refers to any product or service upon which there is a need to retrieve pre-defined information; this product or service may be priced, ordered, or invoiced at any point in the supply chain.
  11. 11. Uniform Code Council & EAN <ul><li>EAN.UCC is worldwide system </li></ul><ul><li>EAN.UCC is comprised of member organizations (M.O.). </li></ul><ul><li>U.C.C. is the U.S. member organization. </li></ul>EAN.UCC M.O. M.O. U.C.C.
  12. 12. Key Benefits <ul><li>Supports worldwide flow of trade goods and services </li></ul><ul><li>Uniquely identifies trade items at all levels of packaging. </li></ul><ul><li>Delivers trade item data in a consistent format and structure. </li></ul><ul><li>Simplifies supply chain management. </li></ul><ul><li>Employs the globally accepted and utilized EAN.UCC System whose language is understood by the global marketplace. </li></ul>
  13. 13. Why GTINs? <ul><li>Allow system-to-system interaction </li></ul><ul><li>Speed processes by enabling end-to-end automation </li></ul><ul><li>Lower costs, while reducing errors </li></ul><ul><li>Reduce the risk of system incompatibility </li></ul><ul><li>Protect technology investments by removing the limitations of closed, proprietary systems and solutions </li></ul><ul><li>Enable the optimization of supply chain management practices </li></ul><ul><li>Eliminate supply chain roadblocks and bottlenecks </li></ul>
  14. 14. Data Structures 0 = leading zero; D = digit, C = check digit A GTIN has a 14-digit data structure though its data carrier (bar code) may contain only 12-digits (the U.P.C.), 13-digits (EAN-13) or 8-digits (EAN-8). The GTIN is defined as a 14-digit number to accommodate all the different structures.
