Barcodes

A barcode reader uses a light source to illuminate the barcode, and then detects the pattern of dark bars and light spaces using sensors. It converts this pattern into an electrical signal that is decoded by a computer to retrieve the information stored in the barcode.

The first three digits "690-699" indicate that a product is organic according to the International Article Number (EAN) system. Sometimes the prefix "8" also indicates an organic product, but it is less commonly used.

A barcode scanner works by emitting light onto the barcode, which reflects back and is captured by a light sensor. The scanner then translates the pattern of light and dark bars into a numerical code that corresponds to the item being scanned. This code is then sent to a database to retrieve information about the product.

Barcode scanners use a light source to illuminate the barcode, which is then reflected back and detected by a photosensitive element that converts the light into an electrical signal. This signal is then decoded and processed by the scanner's software to retrieve the information encoded in the barcode. The decoded information is then sent to a computer or other device for further processing or storage.

Barcode scanners begin by illuminating the code with red light. The sensor of the barcode scanner detects the reflected light from the illumination system and generates an analog signal with varying voltage that represent the intensity (or lack of intensity) of the reflection.

A pipe is a long tube in the ground that connects the magma chamber to the earths surface.

There is a checksum built into the barcode numbers, just as is commonly done for social security IDs, for instance.

An example checksum could be that the last digit in the barcode number should also be the last digit of the sum of all the previous digits, together with a requirement that the digits cannot all be zero. This would not discover every failed scan, but would find the vast majority of them.

In Prison Break, the barcode 38121037 is tattooed on Michael Scofield's body. It is a hidden map to the location of a key that could help him escape from prison. Michael uses the barcode to navigate his plan to break out of Fox River State Penitentiary.
