Bar code equipment

Modern life going faster with each passing day so to transmit the information introduces the new technologies. One of such inventions made ​​over 60 years ago, was the creation of the bar code. Nowadays bar codes are widely used for labeling of products, goods, mail and even auto parts. The bar code scanners are used for instant reading and transmitting of the code to the computer. One can get the encoded data about the product, its manufacturer and other related information by typing the code on the keyboard, as one usually do in case of marker’s damage, but scanning is faster. There are a variety of scanners to operate with a bar code. They are differing in type of the device and in the specific character of the use.

 

There are LED light, laser and image scanners. The LED model is the cheapest, but today not often applied because of the low efficiency and the inconvenience of using. One need to bring the device close to the label to read the information, but this is not always convenient. Laser scanners are more comfortable in use; they read the information from a much longer distance and operate faster. The weak point of these devices is the fragility, but they are well suited for supermarkets, where the cashier is standing in one place. An image scanner is the best model for today. Such device takes a picture of the bar code. Thus, the reading of the information is quick and easy. Their main feature is the ability to recognize even damaged codes.

 

The Companies such as Datalogic and Symbol produce a wide range of image scanners of various specifications, among which one can choose a model that meets all the necessary requirements. There are handheld and stationary devices. The handheld models have an ergonomic shape. The user brings such models to the product. The stationary devices which are brought in small items, often placed on the cash desk. Another type of equipment for operation with bar codes are data collection terminals. The portable devices, in fact, mobile computers with scanning function. These devices help to collect the data on the product in warehouses and large stores, significantly speeding up the accounting process.
