There Are Limitations To Wand Scanners, However

Business.

Bar code scanning systems for your business - the most common use of bar code scanners, and the one that most people are aware of, is the scanning of groceries at a grocery store. The stock control system then feeds back item details and price information to the teller. At the teller the bar code of each package is run past a barcode scanner that tells the system what the item is.

The cost is automatically added to your bill. - if your inventory information was correctly entered into the system when you set it up, inventory control occurs without the need for manual counting or recording of purchases. When the stock control system tallies a purchase, no matter what is actually sold, the inventory records in the central database are simultaneously modified to record the fact that the item has been purchased. The first step towards installing a stock control system is to install the software that is going to keep track of information about your inventory. Each time you scan an item it changes its count in the database. You will use bar code scanners in order to get the information about your inventory into the system.

A system like this one can generate different bar codes for items that need them. - the bar code printer will then print the code label which is then placed on the item. The software will create a one of a kind bar code for each new item. The three most prevalent kinds of bar code scanners available now are: The Wand Scanner - This is the simplest type of bar code scanner. The light from the wand scanner is reflected off the bar code and then the system decodes this signal to recognize the product. A wand scanner is shaped like a pen and has to be touching the bar code to scan it.

It is necessary to keep a wand scanner in touch with the UPC code while scanning it. - it gives off a light that reflects off the upc code, which in turn is decoded by the pos system to recognize the product. The wand scanner, which is a pen - like scanner, is the simplest type of UPC scanner. There are limitations to wand scanners, however. Also, the speed with which it is moved across the barcode can' t be too fast or too slow. The wand needs to be held at a fairly specific angle when pointed at the barcode in order for it to scan properly. Additionally, there is a limit to the resolution of every barcode wand scanner.

For example, a 5 mil barcode cannot be read using a 10 mil wand. - the scanner will not be able to read properly any barcode that has a resolution that is significantly smaller than the scanner itself. When in the market for a wand scanner, it is important that this isn' t forgotten. Similar to the wand scanning device, a CCD reader needs to directly touch the barcode label for it to be able to register the information. The CCD Scanner - The charged coupled device or CCD scanner is a significant step up from the wand scanner. Unlike the wand scanner, the user does, however not have to move the scanner across the label.

The CCD scanner then takes a picture of the barcode, and decodes it, digitizes it. - the user merely puts the scanner next to the reader and engages it. Of the various types of bar code scanners, CCD readers are the easiest to use, and are available in widths from about 2 inches to 4 inches. A new barcode technology similar to CCD is called FFO( Fixed Focus Optics) . A CCD reader is about four times the cost of a wand, but only about one third the cost of a laser scanner. And FFO scnner is a non - contact reader which can read barcodes from as much as 20" away.

The Laser Scanner - Laser scanners use a beam of light to rapidly scan across the bar code label. - they are also able to read two - dimensional barcodes which are going to become more widely used in the future. This means the scanner itself remains stationary, and there is no need for direct contact with the bar code label. This system is widely used in many different types of installations. Scanning is automatic in the sense that the scanning action is initiated when an object is held in front of it. Scanning is such a quick process that it ss even possible to insert laser scanners directly into conveyor systems.

You see this in grocery stores, where the cashier simply moves the items over the scanner to scan them. - as objects move along the conveyor, they are automatically scanned and recorded. This type of system is quick enough to keep up with even the fastest motion of a cashier, and it is quicker and far more accurate than any other alternative system that could be used. This will allow you to keep your system updated without having to replace the entire system in the future. No matter what your ideal scanning system might be today, you need to make certain that you buy a stock control system that allows you to take advantage of future developments in bar code technology.
