Technologies nowadays are fast growing and the ways of calculations are also changed in most grocery stores or supermarkets. If you are not aware of the black thing you can see on the back part of a certain product, that thing is called a barcode. This sort of technology is very vital today especially in fast moving stores like supermarkets.
This system is widely used today in most firms due to the benefits it provides. Though you can always see this on supermarkets this does not suggest that should only be used in that way. You can also used this as a bar coding software for food processors or some other things that involves products and goods. In this posting, we will know the most common type of this system and where it suitable to be used.
First of all we have to understand what exactly is a barcode. A bardcode is more like an optical machine readable data which contains a series of black bars and white spaces of different widths. The primary object of the code is to identify a certain product and that information will then be transferred to a computer system for searching. Once the system found something it will then show up the price related to the product scanned.
For the device to detect the code presented it has essential materials that needs to be used. Commonly it composes of a light source, a decoder and a sensor. This three is essential to properly determine the price and some other information of the product. The light producer will help determind the space and bars of the code. The darker one will absorb the illumination while the spaces will reflect it.
This reflected light will then be received by the detector to process. Since the light intensity varies, it will create a voltage contingent upon how intense the light that has been reflected. The computer program will then further process this to obtain a readable information that humans can read.
The information gathered will then be stored to a database for further processing. The common use of storing the information is for analysis later on which will be conducted with the accounting or the cashier in a certain firm. The information as well can be used to calculate the total payment of a certain customer associated with its grocery ID.
Though they are mostly laser based, some of this technology works on some ways depending on what a establishment is selling. Pin type scanner is actually different from the laser based scanner we usually see. This kind of scanning system is appropriate for lower amounts of goods that needs to be scanned.
On the other hand, if you want a faster scanner with a long range attribute. Then the conventional laser should be used. This is accurate enough that it can read through a code even though it is too far. You do not also need to wait for the scanner to detect the barcode because it is usually instant.
Those are the most common types of bar coding technologies. If you prefer to buy one, do not hesitate to ask the store manager first so that they can guide you on what scanner to go for. You will be amazed how fast the machine works for you and how durable it is.
