FAQs About Bar Coding
The following questions are commonly asked about bar codes:
What are barcodes used for? Barcodes are used by machines to read data. Looking at a barcode, you could probably not tell anything from it, as to the human eye they look like simple black and white lines. These lines represent a machine-readable code that varies depending on the line pattern. When a scanner reads these barcodes, it can then download the data contained in the barcode. For example, once a cashier in the check-out aisle scans a box of cereal, the price is instantly displayed on the register due to the barcode.
What are matrix barcodes? Matrix barcodes, often called 3D or QR codes, are 3D barcodes. You can tell a matrix barcode from a normal barcode because it usually contains strange shapes and dots, as opposed to the traditional lines that are normally seen on barcodes. Seldom used in the grocery store, QR codes are a popular tool for mobile marketing campaigns, since they can be scanned by any smartphone that has downloaded the reader. For this reason, they often appear in advertisements.
What information is in a barcode? Barcodes are popular in businesses because they are cheap and they can let users add their own information to the code. For example, barcodes that are used for retail purposes usually include the name and price of the item, and this information can easily be changed from a computer if the price goes down or up during a sale. Likewise, the matrix barcodes may not include pricing, but they can include other things like a digital image, video, or virtual website link.
Bar coding allows scanners to read labels that provide information about products or gives identification verification. Bar coding is useful in many situations. When you go to the grocery, the clerk checks out your items by holding readable labels with bar codes up to a scanner that can read information like what the product is and how much it costs. This simple process has a lot of technology behind it so you will need to be certain that you pick a bar coding company that can give you the services and products that you need. When you contact the company, ask them how long they have been in business. If a company has worked with bar codes and scanners for several years, then they probably have experience with other machines and technology that is used in the industry such as credit card scanners, ink printers, mobile computing centers, ID readers, UPC codes, data calendars, stored information, readers that recognize patterns automatically, and hidden optical scanners that make it difficult for people to steal from stores. Ask the company if they have readable labels that will fit the products you carry. If you need scanners and readable labels for identification verification cards, then you might need them to work with other media that you use with the ID cards. Ask the company's representation if they can provide a written quote for the machines, computers, labels, and services that you will need. After you have talked to several companies you should be able to pick one that charges a fair price.
