A Quick Way of Reading Bar Codes

A QR Code is an electronic barcode which has a small bar code that contains data about an object.qr code business cards The data is encoded in an invisible grid pattern called a QR Code on a bar code label, or on a product label for example, so the user can scan the code to read the information.qr code business cards qr code business cards These codes are very popular in the digital signage and advertising markets, because they are a quick way of reading the information.qr code business cards qr code business cards

The code starts as a square bar code label, which is then converted to an invisible rectangular grid by means of a computer chip or similar technology, and is then printed onto a label of the correct size for your product.qr code business cards qr code business cards It is then inserted into a camera of the product you are selling, usually on a sticker.qr code business cards qr code business cards

When the reader scans the QR Code, they are sending the reader a coded sequence of dots and dashes, which tells the reader what the code says.qr code business cards qr code business cards qr code business cards qr code business cards If your product has a bar code or magnetic stripe on its surface then this code can be read by any scanner that is able to read these codes.qr code business cards qr code business cards qr code business cards If the product has no bar code or magnetic stripe then you have to use a special QR reader, and if you cannot get hold of one then it will take a long time.qr code business cards

A bar code is usually made up of a series of squares and lines and when you look at it closely you can see that it is easy to interpret.qr code business cards qr code business cards The rows are arranged from top to bottom, with each line containing a number.qr code business cards qr code business cards If you put two items next to each other on the shelf they would both be written in a different column.qr code business cards qr code business cards You could then just have to read the first number to know which item the bar code has written next to it.

A good scanner should have an option that allows the code to be written in many languages, so that you can read the code in Japanese, Chinese or whatever other language your customers will understand.qr code business cards qr code business cards However, many scanners do not allow the code to be written in several languages.qr code business cards qr code business cards If you have a scanner that only accepts one language then you have to use that language in the product you want to sell.qr code business cards

A QR Code can be read by almost any scanner, but some scanners are faster than others.qr code business cards qr code business cards Some can be used at very low speeds, but this is usually because they are slower and don't contain as much data as more modern scanners do.qr code business cards Some scanners may also only read certain languages and not others, which make the customer have to buy a new product to read the code if the code changes.qr code business cards Another disadvantage of a slower scanner is that you can only use it for small bar codes.
