HEARTLAND BARCODE HARDWARE

To read a barcode, you must first determine the barcode type. Barcodes with parallel vertical lines are 1-dimensional. These barcodes are read from left to right. The width of the space and bars relate to specific characters. There are several different character sets, including Code 39 (used by the military), POSTNET (used by the USPS), Codabar, and Interleaved 2 of 5. Each requires a unique method to read.

A normal UPC barcode has 95 bars that are either black or white and represent a set of numbers divided into two sections. The barcode starts and ends with two parallel lines of the same size. You will also find these same two parallel lines in the middle of the barcode. These lines divide the barcode into two sections. The numbers are represented by two black bars divided by white spaces in a seven-space area. All the numbers on the left have an even number of white spaces, and all the numbers on the left have an odd number of white spaces. This is done so barcode readers can determine orientation. Numbers are decoded by mapping these seven space areas and decoding them based on the pattern sets.

The first three digits of a UPC barcode are the country of origin. Barcodes that start with a 0-9 are from the USA and Canada. Other common country codes include:

00 – 09 USA & CANADA
40 – 44 GERMANY
30 – 37 FRANCE
690-692 CHINA
471 … TAIWAN
49 … JAPAN
50 … UK

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.

The iPhone will read a UPC barcode using the camera APP. Open the rear-facing camera, hold the iPhone, so the QR code appears in the viewfinder, and it should recognize and read the QR code. There are many other types of barcodes, and there are apps for most of them in the iPhone store.

A barcode reader optically scans printed barcodes, decodes the data, and sends the data to a computer or displays it on a screen. Barcode readers consist of a light source, a lens, and a light sensor translating for optical impulses into electrical signals.
