The father of the barcode label died

Norman Joseph Woodland - one of two American scientists who invented the barcode set - died of Alzheimer's disease and other complications in the elderly.

According to the family's announcement on December 13, Mr. Woodland breathed his last breath on December 9 in Edgewater, New Jersey, USA, aged 91.

Mr. Norman Joseph Woodland and Bernard Silver attended the school today as Dreexel University in Philadelphia.

Once, Mr. Silver "overheard" that the grocery industry executives asked the school's technical department leadership to direct students to study how to capture product information to check.

Now, Mr. Woodland only knew Morse cryptography when he joined Scouting. One day, when he wrote Morse code with two types of dots (.) And (-) signals on sand in Miami Beach (Florida), he suddenly came up with the idea why not replace dots and lines with those thick and thin lines.

Woodland and Silver filed a patent on the bar code set in 1949, in their original form with rounds of gun-like circles. This patent was published in 1952. Mr. Silver died in 1963.

Mr. Woodlan joined IBM in 1951 in hopes of developing a barcode set. However, this technology has not been accepted and the rectangular barcode set is only applied after the laser reading device in the 1970s.

So far there are about 5 billion products with barcode labels. Mr. Woodland with Microsoft founder Bill Gates is one of the White House's honors for technological achievements in 1992.
