Is the barcode the Mark of the Beast?
Do barcodes really contain the number 666?
Is the barcode paving the road to 666: the Mark of the Beast?
Before we answer these questions, we need to briefly examine the barcode technology.
What are barcodes?
Barcodes, of course, are those ever-familiar "bars" and "numbers" on virtually everything. In 1973, "Mr. Barcode" (or is it Mrs. Barcode?) quietly strolled into our world. In just over 25 years, Mr. Barcode has literally taken over the world. Now there's a barcode for virtually everything. There's short barcodes, and tall barcodes. There's skinny barcodes and fat barcodes. There's postal barcodes and international barcodes. There's 2-D barcodes. And there's even barcodes for the humble "bumble-bee". From letters, to cokes, from fishes to smokes - it's "clothed" with friendly "Mr. Barcode".
As someone truthfully said, "If it exists, bar code it".
The primary barcode used in the United States is the UPC (Universal Product Code) barcode. The UPC is also the "original" barcode. The UPC was designed for the grocery industry. Because of the large number of items normally "checked-out" at the grocery store, a method was needed to speed up and eliminate "human" cashier errors. In 1973, the UPC barcode was born.
To the average person, the barcode looks confusing and complex, but to a "bar-coded" friendly computer, it's actually very simple.
How does a computer-scanner reads a barcode?
A single barcode number is actually seven units. A unit is either black or white. A unit that is black would display as a "bar". A unit that is white would display as a "space". Another way of writing a barcode unit is "1" for a single unit "black bar" and "0" for a single unit "white space". For instance, the number "1" is composed of the seven units, "0011001" or "space-space-bar-bar-space-space-bar". Remember, a single barcode number requires seven units.
Also, on a UPC barcode the same numbers on the left-hand side (the Manufacturer Code) is coded different than the numbers on the right-hand side (Product Code). The left side numbers are actually the "inverted" or "mirrored" codes of the right side numbers, for instance what is a "bar" on the right-side, is a "space" on the left-side. The right-side codes are called "even parity" codes because there is an even number of "black bar" units. For instance the right-side "6" is "101000" - 2 even-numbered "black bar" units. The left-side is called "odd-parity" because there is an odd number of "black bar" units. For instance, the left-side "6" is "0101111" - 5 odd-numbered "black bar" units. Having different coded numbers for each side allows the barcode to be scanned in either direction.
The following tables are the left and right side codes matching the corresponding numbers, separated into the seven single units.
