FC: History on Barcodes

1: About the Inventors Bernard Silver was a grad student at Drexel. The idea of having barcodes fascinated him. He then talked with a good buddy by the name of Norman Joseph Woodland about helping him make this happen. At the time Norman was 27 years old and a teacher at Drexel. (Seideman) Bernard knew Norman from school, which was Drexel University in Philadelphia, PA. (Seideman) Norman fell in love with barcodes. He loved the idea so much that he decided to stop working as a teacher at Drexel. As he got more in depth with the project of barcodes he decided to move to Florida with his grandfather for extra help. (Seideman)

2: How did Bernard come up with the idea of Barcodes? Bernard Silver overheard a meeting going on between the President of Food Chains talking to a Dean at Drexel about doing a research on having automatic information on a product at checkout. But the request was turned down. (Seideman)

4: 1948 is when Bernard began working to make barcodes.But the computers of that time period could only perform simple calculations. (Seideman)

6: The first types of Barcodes

7: After several months on working with barcodes he came up with the linear barcodes, by using two technologies that have already been invented which were movie soundtracks and Morse codes. (Seideman) | Although the wide and narrow barcodes could work, they decided to test a circular barcode. They replaced the lines with centric circles. He wanted it to be scanned from any direction. (Seideman)

9: Bernard's first idea was that he wanted to use "patterns of ink that would glow under ultraviolet light"(Tony). They built a device to test the patterns. It was successful, but because of the ink cost and the quality it could possibly not work. (Seideman)

10: In 1952 Silver and Woodland actually tried to create the first barcode scanner. The tried this at Woodlands Living Room in Binghamton, NY. The size of the scanner was the size of a desk. Also, had to be wrapped in black oil to protect from ambient light.The scanner relied on 500 watt bulb. It failed by the paper catching on fire, nonetheless the reader (oscilloscope) did detect the lines. (Seideman)

12: Their attempt to make their first scanner failed by the reflected beam of light caught the barcodes on fire but, the scanner did recognize the codes. (Seideman) | =

13: The experiment convinced Norman to keep working and to fix their problems. The experiment also let them know that it WILL work, eventually. Printing cost came in their way of it not working (Seideman) | The first experiment encourages them to keep them working on their idea and also gave the hope. (Seideman)

14: Barcodes began to appear in stores in the 1970's | (Seideman)

15: In 1966 RCA Executives held a meeting with the grocery industry where bar codes will need to be installed into the groceries of that time. (Seideman) In the mid 1970’s an industry looked into barcodes.(Seideman) The first ever barcodes was used for a 10 pack of Wrigley Gum. (No Author but URL)

16: Barcodes are used for practically everything. You need them to purchase your items. Barcodes work by “reading” the symbols of the barcode. That information then is pulled up onto the computer.

17: Without the barcodes the registrar will not be able to know the price of the item. This also, helps with keeping up with amount of that product and stocks organized.

18: We need barcodes because they save us time and organized our purchasing system.

19: 5 weeks after the first ever barcode scanners were installed in stores, sales went up by 10 to 12 percent. This overall improved sales for many businesses. | (Zidan)

20: A world with out barcodes......

21: Without barcodes our world would be very behind in the technological world. Everyone would need to have grocery cards in order to purchase what they need. Prescriptions for medicine would take longer to order and could possibly mix up the drugs.

22: Examples of what Barcodes are used for today:

23: Someone decided to put tiny barcodes on bees to track their mating habits. The US Army puts barcodes on storage 50ft. boats. At the hospital many people have ‘barcodes’ to signify who they are and if they can enter; Such as nurses, EMTs, and patients. | (Seideman)

24: Positives of Barcodes | -Saves time -Organized stocks -Holds a lot of info. -Calculates price for you -Uses low energy light beams (Scanners) -Helped Economy

25: Negatives of Barcodes | -Sometimes they don't work -Have to be programmed a lot. -Must sync with the scanner -Self Services are complicated to work with -Scanners can be slow to recognize the barcode -Makes us dumber
