Funny Facts about BarCodes

Today is the most suitable day to remember some interesting stories about barcodes.

Funny Fact 1: In Seattle, QR codes are inscribed on graves which contain link to the detailed information about the deceased person

Funny Fact  2: The first patent for bar code was issued to inventors Joseph Woodland and Bernard Silver on October 7 of 1952.

Funny Fact 3: Wrigley’s Gum was the first product to have a barcode included in June of 1974, at a Marsh’s supermarket in Troy, Ohio. There was installed the 1st UPC scanner too. 

Funny Fact 4. Some religions believe that the global use of barcodes is an indication that we are living in the ‘last days’, as they all contain the number 666 in them (either the number set or the control sum).

Funny Fact 5. Maths and barcodes are together. Check any product with the EAN8 barcode, doesn’t the retailer make a mistake in it?

The check digit is chosen (we are checking EAN8 barcodes now) so that

3 x (1st + 3rd + 5th+ 7th number) + (2nd + 4th + 6th + 8th number)

is exactly divisble by 10.

Right barcode? Congratulations! Both you and the retailer are very good in maths!
