Types of Bar Code Readers
In a complete system radio frequency used for automatic product identification through barcode, one of the essential components of operations is, without doubt, code readers.
Currently on the market a wide range of readers (scanners) barcode, which differs not only for price but also for the services offered to facilitate data capture encrypted barcodes that accompany products.
One of the most popular has always been called the reader stylus, which for years has been chosen , especially retailers, because of their low cost and small size and manipulable .
However, many users prefer to use other devices , because readers pencil require extensive ability to handle the device manager , are not very resistant to shocks and falls and offer a slow reading and sometimes not fail to capture the information of the code, since they only work well with codes that are printed in excellent quality.
Another model widely used are usually those scanner CCD type , which use a photodetector CCD sensor type , ie, a charge-coupled device , which contains a set of LEDs, which are responsible for emitting light sources and how to get the code information .
While these devices require that the code is in physical contact with the reader to make reading possible , the truth is that they offer a fast and efficient reading, since unlike the scanner stylus produced no degradation image when it is scanned .
Within type CCD readers , is also a model but does not require direct contact with the code , allowing a reading proximity , the fact is they do not work correctly with uneven surfaces.
Regarding the type of laser scanners , most models available today often allow efficient and fast proximity reading the barcode .
As the name implies are characterized by allow reading codes in either direction, because they are composed of a set of mirrors that produce a omnidimensional pattern. They are commonly used in supermarkets, as they are the most recommended for an accurate and immediate, error reading.
Other less popular readers, because they are usually the most expensive, are the kind of self that are generally used in the production plants within the area of the conveyor belts.
This type of scanner allows for efficient data capture, regardless of the direction, type of barcode, the surface where it is printed and fitness.
Also, in recent years has been incorporated barcode reader 2D, also used in the manufacturing plants, which allow the bar code reading in two dimensions, such as the Datamatrix and Maxicode.
Regardless of the type of bar code readers and devices that are selected for automatic identification of products, the fact is that one of the key components will be the implementation of an effective system of RF.

stylus
One of the most popular has always been called the reader stylus, which for years has been chosen , especially retailers, because of their low cost and small size and manipulable .

Laser devices
Omnidirectional fixed Laser
As the name implies are characterized by allow reading codes in either direction, because they are composed of a set of mirrors that produce a omnidimensional pattern. They are commonly used in supermarkets, as they are the most recommended for an accurate and immediate, error reading.
readers Autonomous
Other less popular readers, because they are usually the most expensive, are the kind of self that are generally used in the production plants within the area of the conveyor belts.
This type of scanner allows for efficient data capture, regardless of the direction, type of barcode, the surface where it is printed and fitness.
2D reader
Also, in recent years has been incorporated barcode reader 2D, also used in the manufacturing plants, which allow the bar code reading in two dimensions, such as the Datamatrix and Maxicode.
Regardless of the type of bar code readers and devices that are selected for automatic identification of products, the fact is that one of the key components will be the implementation of an effective system of RF.
