Barcode Solutions

Barcode is a machin-readable representation in a visual format on a surface. Barcodes can be read by optical scanners called barcode readers or scanned from an image by special software. The use of these products help in reducing time and costs associated with the processing. These solutions help user in keeping up to date record of inventory.          

Employee/ student can not only clock in with the software but the software will also enter the information for the later use. This means you don't have to punch in the information when calculating payroll because it is already entered for you. These solution can save time and money for you. It eliminates the cost of using employees to do the work that can be easily done by using our products. In, addition, it eliminates the human error factor. This can also save time and money.

Product of Barcode Reader

   Pen-type Reader

Pen-type readers consist of a light source and photo diode that are placed next to each other in the tip of a pen or wand. To read a bar code, the person holding the pen must move the tip of it across the bars at a relatively uniform speed. The photodiode measures the intensity of the light reflected back from the light source as the tip crosses each bar and space in the printed code. The photodiode generates a waveform that is used to measure the widths of the bars and spaces in the bar code. Dark bars in the bar code absorb light and white spaces reflect light so that the voltage waveform generated by the photo diode is a representation of the bar and space pattern in the bar code. This waveform is decoded by the scanner in a manner similar to the way Morse code dots and dashes are decoded.


Laser Scanner
Laser scanners work the same way as pen type readers except that they use a laser beam as the light source and typically employ either a reciprocating mirror or a rotating prism to scan the laser beam back and forth across the bar code. As with the pen type reader, a photodiode is used to measure the intensity of the light reflected back from the bar code. In both pen readers and laser scanners, the light emitted by the reader is rapidly varied in brightness with a data pattern and the photodiode receive circuitry is designed to detect only signals with the same modulated pattern.


CCD Reader
                                                   
 CCD readers use an array of hundreds of tiny light sensors lined up in a row in the head of the reader. Each sensor measures the intensity of the light immediately in front of it. Each individual light sensor in the CCD reader is extremely small and because there are hundreds of sensors lined up in a row, a voltage pattern identical to the pattern in a bar code is generated in the reader by sequentially measuring the voltages across each sensor in the row. The important difference between a CCD reader and a pen or laser scanner is that the CCD reader is measuring emitted ambient light from the bar code whereas pen or laser scanners are measuring reflected light of a specific frequency originating from the scanner itself.


Camera-based Reader


Two-dimensional imaging scanners are the fourth and newest type of bar code reader. They use a camera and image processing techniques to decode the bar code.
Video camera readers use small video cameras with the same CCD technology as in a CCD bar code reader except that instead of having a single row of sensors, a video camera has hundreds of rows of sensors arranged in a two dimensional array so that they can generate an image.






Omni-directional barcode scanner

Omni-directional scanners are most familiar through the horizontal scanners in supermarkets, where packages are slid across a glass or sapphire window. There are a range of different omni-directional units available which can be used for differing scanning applications, ranging from retail type applications with the barcodes read only a few centimetres away from the scanner to industrial conveyor scanning where the unit can be a couple of metres away or more from the code. Omni-directional scanners are also better at reading poorly printed, wrinkled, or even torn barcodes.

About Barcode

A barcode is an optical machine-readable representation of data, which shows data about the object to which it attaches. Originally barcodes represented data by varying the widths and spacing of parallel lines, and may be referred to as linear or one-dimensional (1D). Later they evolved into rectangle, dots, hexagons and other geometric patterns in two dimensions (2D). Although 2D systems use a variety of symbols, they are generally referred to as barcodes as well. Barcodes originally were scanned by special optical scanner called barcode readers  later, scanners and interpretive software became available on devices including desktop printers and smart phones.The first use of barcodes was to label railroad cars, but they were not commercially successful until they were used to automate supermarket checkout  systems, a task for which they have become almost universal. Their use has spread to many other tasks that are generically referred to as automatic identification and data capture (AIDC).


A barcode system is a network of hardware and software, consisting primarily of mobile computers, printers, handled scanner, infrastructure, and supporting software. Barcode systems are used to automate data collection where hand recording is neither timely or cost effective. Bar coding systems are not radio-frequency identification (RFID) systems even though the companies that provide barcode equipment will often also provide RFID equipment and many companies use both technologies as part of larger resource management systems.
