7 Today s Objectives By the end of this Webinar, you will know: The lineage of 2D Symbologies The structure of common 2D Symbologies Why 2D Symbologies are so popular in so many markets

8 Today s Topics Evolution from Linear to 2D 2D Stacked Symbologies: PDF417 2D Matrix Symbologies: Data Matrix 2D Matrix Symbologies: QR Code

9 Evolution from Linear to 2D As the need for higher capacity codes arose, compact codes were developed First introduced were 2D stacked: several 1D type codes stacked on top of each other Then 2D Matrix: data encoded in 2 Directions 1D symbols encode in one direction, 2D encode in 2 directions 2D symbols contain more data in less space Code 39 Code 49 PDF 417 QR Code

Evolution from Linear to 2D Early Stacked Symbologies Code 49, Code 16K Developed in the late 1980s Encodes more data than standard linear codes Sensitive

10 Evolution from Linear to 2D Early Stacked Symbologies Code 49, Code 16K Developed in the late 1980s Encodes more data than standard linear codes Sensitive to tilt angles on laser scanners Code 49 is considered the first 2D symbology Code 16K is similar to code 49 but can contain more data and is more efficient

11 2D Stacked Symbologies: PDF417 PDF 417 Parable Data File, 4 bar/space, 17 modules Introduced in 1990 AIM Standard Margins on sides, top, and bottom Reed-Solomon Error Correction (ECC or ECL) Levels 0 5 Reduces Truncation: missing characters Reduces Substitution: incorrect characters Tilt angle consideration

2D Matrix Symbologies: Data Matrix History Developed in mid-1990s AIM Standard soon follows Symbol sizes range from 10 x 10, up to 144 x 144 rows x columns Up to

12 2D Matrix Symbologies: Data Matrix History Developed in mid-1990s AIM Standard soon follows Symbol sizes range from 10 x 10, up to 144 x 144 rows x columns Up to 3116 numeric, 2335 alphanumeric characters Small, easy to print and decode, secure Most common in DPM applications Microscan holds the original Data Matrix patents

13 2D Matrix Symbologies: Data Matrix Structure Element Also known as: cell, module Square shaped cell that encodes one bit of binary data 0 or 1 Consistent size throughout code The color of binary 1 is the same as the L-pattern Element measurement determines resolution Quiet zone Also known as: margin, no print zone Required: 1 element size around all sides For best performance: 20% of symbol size

14 2D Matrix Symbologies: Data Matrix Structure Locating Pattern Clock Pattern: Two sides are alternating light and dark elements. Used for synchronizing the decoding process. L-Pattern: Two solid lines, forming an L Data Region The area inside the finder pattern Contains data and error correction

15 2D Matrix Symbologies: Data Matrix Data Regions High capacity symbols contain multiple data regions Each data region can contain up to 88 numeric or 64 alpha/numeric characters Error correction repeats through the entire symbol Multi-Region Data Matrix Data Region Alignment Patterns

2D Matrix Symbologies: Data Matrix Error Correction ECC 0

ECC 200 Introduced in the late 1990s Reed-Solomon calculation

standard Allows rectangular codes Upper right corner element

16 2D Matrix Symbologies: Data Matrix Error Correction ECC 0 through ECC 140 Original versions Convolutional check digit ECC 200 Introduced in the late 1990s Reed-Solomon calculation allows up to 60% of the data region to be damaged The current standard Allows rectangular codes Upper right corner element is always binary zero ECC 0 ECC 140 ECC x 32 ECC 200 Rectangular

2D Matrix Symbologies: QR Code History Quick Response Code Introduced in 1994 by Nippondenso Sizes from 21x21 to 177x177 Up to 4296 alphanumeric, or 1817

17 2D Matrix Symbologies: QR Code History Quick Response Code Introduced in 1994 by Nippondenso Sizes from 21x21 to 177x177 Up to 4296 alphanumeric, or 1817 Kanji characters Small, easy to print and decode Popular in Asia because of simple Kanji & Kana character support Becoming more popular in retail using smart phones

18 2D Matrix Symbologies: QR Code Structure Element Cell, module Square shaped cell that encodes one bit of binary data 0 or 1 Consistent size throughout code The color of binary 1 is the same as the position detection pattern Quiet zone Margin, no print zone Minimum of four times the element width (4X) on all sides of the symbol

19 2D Matrix Symbologies: QR Code Structure Locating Patterns Three position detection patterns are used to locate the symbol, and determine orientation Data Region The area that contains data and error correction code words

20 2D Matrix Symbologies: QR Code Error Correction Reed-Solomon Four levels: L, M, Q and H Higher correction levels generate larger codes ECC level and recovery Level % of damage L 7% M 15% Q 25% H 30%

21 Introduction to 2D Symbologies Conclusion Evolution from Linear to 2D Space constraints: a lot of data in a small amount of space Error correction: damaged symbols still decode ideal for DPM 2D Matrix Symbologies: Data Matrix & QR Code Similar structure between these 2D Symbologies Margin Locating pattern Data region & Error Correction Many applications now using 2D technology Automotive Electronics DoD / Aerospace Document Handling Packaging Pharmaceutical
