Punch Cards

Paper cards with several holes First used in 1795 to control textile looms Applied to supermarkets in 1932 Disadvantages: heavy and expensive

reading equipment

6

Bull’s Eye Barcode

Circular shape and structure Invented in 1948 by Bernard Silver and

Joseph Woodland. Received a patent in 1952

UPC Barcode

The Universal Product Code or the 1-D Barcode is the format for product barcodes in the U.S. and Canada. They are used in retail stores.

Types of UPC barcodes:UPC-AUPC-E

8

UPC Barcode

UPC-A Suitable for the retail point-of-sale (POS) Omnidirectional Capacity: GTIN (Global Trade Item Number) - 12

numbers consist of 11 data digits and one Modulo 10 checksum.

9

UPC Barcode

The number system digit’s values have different meanings. Regular UPC codes have values 0,1,6,7 and 82 represents random weight products3 represents Items of National Drugs4 represents non-food products5 and 9 used on coupons

10

UPC Barcode

UPC-EAn abbreviated form of UPC-A codesUsed on small packagesOmnidirectionalCapacity: GTIN-12 Numeric, zeroes

suppressed

Barcode ScannersWho

invented the first scanner?

Where it was

installed

What was the first

item to be scanned?

The first scanner was invented by George Laurer.

At Marsh’s supermarket.

A packet of Wrigley's Gum

12

Barcode Scanners

Five different types of scanners were developed over the years:

Pen/wand scanners Slot scanners Charge Coupe Device (CCD) scanners Camera based scanners Laser scanners

13

The Wand Scanner

How does it work? Must be in contact

14

The Slot Scanner

Operates in different manner when compared to wand scanner

15

The CCD Scanner

How does it work? Contactless – distance of item cannot exceed

1 inch Disadvantage of CCD scanner

If barcode is bigger than

scanner’s screen, it won’t read it

16

The Camera-Based Scanner

How is it different? It can read barcodes that are up to 9 inches

apart

17

The Laser Scanner

Uses same technique as the wand scanner; what is the difference?

Contactless It can read barcodes that are

up to 24 inches apart Minimum error percentage

18

Future of the Barcode

Quick Response (QR) Codes A two dimensional barcode read using

smartphones or QR reading devices Invented by Denso-Wave in 1994 Scanning is done using phone’s camera Ideal placement location

19

Types of QR Codes

QR Code Model 1 and Model 2

Micro QR Code IQR Code SQRC Frame QR

20

Applications of QR Codes

Can be printed on newspapers, books, letters, dresses, business cards and tattoos

21

Conclusion

Allowed businesses to save time and money Has made shopping a lot quicker and

reduced queueing times Standardisation to the UPC barcode QR Codes: How barcodes are moving with

new technologies
