1D, 2D Barcodes or QR Codes. What’s the best?
2D (2 dimensional) barcodes are designed to contain more information than conventional, one dimensional (1D) linear barcodes. Conventional barcodes become wider as the amount of data required increases because they use only the width of the bars and spaces (single dimension) to read and decipher the code. Conversely, 2D barcodes make use of both the horizontal and vertical dimensions which allows more data to be stored in a much smaller area such as product packaging where space can be limited.
What’s the solution?
If your label requires only a few characters (up to about 15) then a 1D barcode is probably the best solution. However, as a result of their construction, some 2D barcodes are capable of storing over 7000 characters which is why they have increased in popularity with manufacturers. QR Codes is an example of this.
What are QR (Quick Response) Codes?
Quick Response Codes are a type of 2D barcode first designed for the automotive industry in Japan. A subsidiary of Toyota (Denso-Wave) have been attributed with the creation of the QR Code in 1994 when it was originally designed to track parts in vehicle manufacturing. Nowadays, they can be read using smartphones and dedicated QR reading devices that link directly to text, emails and websites. At Aspect Labelling we use them to form a part of a label, for example, within an asset label.
In its simplest sense, a QR code is an image based link allowing any URL to be encoded into it so, essentially, any web page can be opened automatically as a result of scanning the barcode.
In addition to website URLs, a QR Code can also contain a telephone number, so when it is used it prompts the user to call a particular number.
