1 Retail Bar Coding Basics a Tutorial

2 Is bar coding necessary? Reasons for UPC bar codes. Want to sell your products via retail stores. Products are sold at checkout counters. Product is a food item or consumer retail item. Reasons UPC bar codes not necessary Bar codes are only for internal use such as inventory Products are not sold via retail stores. Products are not sold at checkout counters

3 History of Retail Bar Codes 1932 Wallace first to suggest automated checkout 1948 Drexel University begins research into auto ID method 1949 Woodland & Silver build prototype scanner. 1952 Patent granted Woodland & Silver for Auto ID method 1966 First commercial use of bar codes 1970 First commercial Auto ID product 1972 Kroger stores begin using ‘bulls-eye’ bar code 1973 Uniform Product Code standard adopted 1974 First UPC scanners commercially marketed 1974 First product (Wrigley Gum) UPC bar coded.

4 What is a Bar Code? A bar code (barcode) is similar to “Morse Code” in that they both encode character information. Morse Code was developed in 1935 and consists of s code based on short and long electrical impulses. dit 1 unit of time dah 3 units of time pause between letters 3 units of time pause between words 7 units of time

5 What is a Bar Code?

7 What is a Bar Code? Step 1: Designate the least significant digit position as odd. 3 1 4 5 7 9 0 1 2 5 8 O E O E O E O E O E O Step 2: Sum all the digits in the odd (o) positions 3 + 4 + 7 + 0 + 2 + 8 = 24 Step 3: Multiply the result by 3 24 * 3 = 72 Step 4: Sum all the digits in the even (E) positions. 1 + 5 + 9 + 1 + 5 = 21 Step 5: Add the result of Step 2 with the result of Step 4. 72 + 21 = 93 Step 6: Subtract from the next higher multiple of 10. 100 - 93 = 7. In this example, the check digit is 7. Check Character Calculation (UPC)

8 How a Bar Code Works Light from the scanner (laser, LED, or other) reflects off the label back to a sensor in the scanner

9 Bar Code Symbologies The manner in which the bars and spaces are encoded define the bar code symbology Codabar Code 128 Code 3 of 0 Code 93 EAN 13 EAN 8 ISBN Interleaved 2 of 5 MSI / Plessey Postal / Postnet UPC A UPC E PDF-417

10 Global Trade Identification Numbers 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. 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 Uniform Code Council & EAN EAN.UCC is worldwide system EAN.UCC is comprised of member organizations (M.O.). U.C.C. is the U.S. member organization. EAN.UCC M.O. U.C.C.

12 Key Benefits Supports worldwide flow of trade goods and services Uniquely identifies trade items at all levels of packaging. Delivers trade item data in a consistent format and structure. Simplifies supply chain management. Employs the globally accepted and utilized EAN.UCC System whose language is understood by the global marketplace.

13 Why GTINs? Allow system-to-system interaction Speed processes by enabling end-to-end automation Lower costs, while reducing errors Reduce the risk of system incompatibility Protect technology investments by removing the limitations of closed, proprietary systems and solutions Enable the optimization of supply chain management practices Eliminate supply chain roadblocks and bottlenecks

The GTIN is defined as a 14-digit number to accommodate all the different structures.
