Barcode Scanners Information

A barcode scanner (or barcode reader) is a computer peripheral for reading barcodes printed on various surfaces. A barcode reader consists of a scanner, a decoder (either built in or external), and a cable used to connect the reader with a computer. In addition, nearly all barcode readers currently produced contain decoder circuitry analyzing the barcode image data made available by the photo management and sending the barcode content for the output of the scanner interface.

Types of barcode scanners: —

By Technology: —

• Pen type readers: Pen type readers consist of a light source and a photodiode, side by side placed in the tip of a pen or wall. To read a bar code, tip of the pen moves in all the bars in a steady even motion.

• Laser Scanner: Laser Barcode Scanner 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 compressor or a rotating mirror Prism to scan the laser beam back and forth across the barcode.

• CCD reader: CCD (Charge Coupled Device) readers (also referred to as LED scanner) an array of Hundreds of tiny light sensors lined up in a row in the mind of the reader. The main 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 measure reflected light of a specific frequency originating from the scanner itself

• Camera-Based Readers: 2D imaging scanners are the fourth and newest type of bar code readers currently available. They use a small video camera to capture an image of an Barcodes. The reader then uses sophisticated digital image processing to decode the bar code.

The Case: —

• Handheld Scanner: With a handle and typically a trigger button to turn on the light.

• pen scanner (or wand scanner): A pen-shaped scanner that is stolen.

• Stationary scanner: wall or table mounted, given that the bar code scanners, in addition to or. These are often found at checkout counters of supermarkets and other retailers.

Bar code applications for the consumer: —

While bar code readers are typically used in retail, warehouses and industrial, low cost bar code reader opens up a number of applications for the individual consumer.

· Movies: DVD / VHS movie catalogs

· Music: CD catalogs, MP3 playback, when scanned

· Book Catalogs

· Food, nutritional information, shopping lists as if the last one element, etc.

· Personal Property Inventory (for insurance and other purposes)

· Cataloging property stored in boxes in the garage, basement, attic, self-storage units, etc., to easily found, the sales income from e-bay, etc.

· Calling cards: 2D barcodes can store contact information for the import.

· Brick and mortar shopping: Portable scanners can be used to locate objects of interest to record the shows you are online when you go home.

· Coupon management: weeding expired coupons.
