to ensure bar code reader for a better functioning business with efficient and accurate automatic identification of products. develops technologies for various bar codes to help track inventory tracking, monitoring of resources, increase operational efficiency, improve employee productivity, etc. various types of bar code technology is effective in areas such as health, 'hospitality, retail, manufacturing, distribution, storage,etc.
Barcode Reader Technologies:
The decision to bar code reader technology depends on the type and bar-code for the environment that are used in scanning and requires the type of connection (eg USB, serial or keyboard).
Readers Pen-Style
Pen-style bar code reader, which also includes a wall bar code reader, known to be a source of light and a photodiode near the tip of the pen. Since the pin on the bar code, theftPhotodiode measures the intensity of light reflected from the surface. A waveform is the exact width of the bars and spaces created in the barcode represents. The dark color to absorb the beam, while the white areas reflect light, creating a specific model of the waveform. This waveform is then converted by the pen-type reader to retrieve product information quickly. Since the players are on the wall in the bar code manually spread are not limited by the width of the barcode.They require the user to the wall above the bar code to pass a uniform rate of speed and at an angle. Reader's Art Pen scanners are not the most efficient, but they are small, extremely durable and economical. Pen-style bar code reader suitable for low volume and desktop applications.
Laser Scanner
Bar code scanner laser bar code offer more readable, like a laser beam instead of light. An oscillating or rotating mirrorPrism is used for the laser beam back and forth to move across the bar code. The brightness and sharpness of the laser beam provides more precision and accuracy when reading bar codes. Laser scanners can read barcodes from longer distances and are designed for applications where bar codes are designed to be seen in full light is ideal.
CCD Readers
CCD (Charged Coupled Device) readers, bar code scanners as a linear sensor, consisting of a series of small and light sensors, which measure the intensity ofLight directly in front of them. Linear Imager can be effectively read barcodes from a few centimeters to several meters. They are robust and are designed to withstand harsh working conditions. Linear Imager for use in various sectors like retail are subject to shipping, receiving and inventory.
Based on player camera
The latest technology in bar code reader, camera, barcode scanner or 2D imager. to look with a small cameraImage of the barcode and then processed to decode the image using advanced techniques of digital image processing for the barcode. This player produces a picture with hundreds of sensors arranged in rows. 2D bar code scanner can include information from bar code labels that are wrinkled or damaged. These scanners are able to move quickly to bar codes, as read in boxes on a conveyor belt. 2D bar code scanner for reading barcodes omnidirectionally so that bar codes in any orientationWind direction. Some scanners can capture 2D bar codes and digital images and signatures.
Omni-directional Barcode Scanners
omni barcode scanners, laser beams are scattered in all directions, you can read bar codes from any angle. A rotating mirror and a series of fixed mirrors are used omni-directional bar code scanner, to generate the model of laser beams. These scanners have changed as a function of scanning bar codes for scanning on a fewcm to several meters. omni-directional barcode scanner can be placed in retail, which must use the barcode to a few centimeters or in areas where they can read bar codes are read from a distance of few meters in difficult conditions. It 'can read bar codes even when torn, wrinkled or damaged.
Cell Phone Cameras
The application of scanning bar codes are now available for mobile cameras. Some 2D barcodes, such as QR and Data Matrix codes are optimized forScan cell. Although this technology is still under development, will open a wide range of opportunities for potential applications. Currently, some phones with the iPhone and Google Android platform, applications of scanning bar codes. Most of these applications are developed as a commercial tool. You use the Google bar for tracking numbers, a number of websites such as Amazon and pull up product information, price comparisons and reviews. Some will evenLocate the GPS to use the phone to the store the goods within the bar code reader, mobile transactions, alongside other applications such as access to ticket holders at the clubs, personal finance, reporting, 's inventory, monitoring activities, etc. are made
The barcode reader should be based technology companies will be selected for each specific application. "The bar code readers must be fast, easy to use and robust enough to withstand working conditions in bothan office, shop, factory, warehouse or outside in the garden of a work or vehicle.
