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

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.

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

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

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

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
