Today’s Google Doodle: Invention of the Bar CodeCategory: Computers
If you happen to visit Google’s homepage today, you will notice that its logo is replaced by a series of vertical lines parallel to each other.
Yes, that is a doodle of a barcode.
Fifty-seven years ago, on October 7, 1952 to be exact; US Patent 2,612,994 was issued to Norman Joseph Woodland and Bernard Silver thereby recognizing them as the owners and inventors of the barcode.
A barcode is an optical machine-readable representation of data. Originally, bar codes represented data in the widths (lines) and the spacings of parallel lines, and may be referred to as linear or 1D (1 dimensional) barcodes or symbologies. They also come in patterns of squares, dots, hexagons and other geometric patterns within images termed 2D (2 dimensional) matrix codes or symbologies. Although 2D systems use symbols other than bars, they are generally referred to as barcodes as well.
Bar codes can be read by optical scanners called bar code readers, or scanned from an image by special software. (source: Wikipedia)
Bar codes are usually used to track items which range from grocery items to rental cars to mails and parcels to cinema tickets and even nuclear waste and DNA.
Who knows, there might even come a time where our national ID system is composed of a bar code branded to our butts. 😀
