What is the QR Code - What is a QR code??

Accepted Answer

QR stands for quick response  A QR code is a 2D matrix barcode  where a 1D barcode stores information as a series of lines that must be read in a linear direction  a 2D matrix uses modules  square dots or cells  that are arranged in a specific square or rectangular pattern that is scanned as a whole image  allowing more information to be stored in the same area  QR codes are usually square in shape and use black modules on a white background to create specific patterns in black and white  although colours can also be used         The code is scanned by an imaging device  such as a 2D barcode reader or a camera on a smartphone   standard QR codes have three larger squares  which are used to define the edges of the code  and one or more smaller squares to determine the size  orientation  and angle of view of the code  The image is validated using the Read-Solomon error correcting code and the patterns created by the modules are converted into binary numbers  which represent the information stored in the code         QR codes usually store information about the item they are attached to  but they can also perform functions such as displaying a particular message  launching a particular webpage  or even purchasing a particular item  QR codes are a popular way of hardlinking or object hyperlinking  an item can be labelled with a QR code containing a URL that  once scanned  will instantly launch a webpage on an individual's device to allow them to buy the item  find out more about the item  whether an item is in an advert  on display in a store  or is an item on display in a gallery or museum   or simply provide contact information relating to the business or individual who produced the item or provides a particular service relating to the item         QR codes are most commonly used on products for tracking or information purposes  but are increasingly used on advertising materials ranging from small individual leaflets  magazine and newspaper adverts  to billboards and posters         The easiest way to generate a QR code is to search online for a QR Generator  which will create a QR code based on the information you enter  The easiest way to add a QR code onto an item is to print it onto a self adhesive label  Your QR code label can then be stuck directly onto the item itself  onto its packaging  or in a prominent position nearby           We recommend using a white label with a matt finish as this provides a clean image for devices to scan and read  A black QR code on a white background creates the clearest contrast  while a matt finish provides a non-reflective surface for devices to scan  At Label Planet  we supply a variety of suitable matt white labels  including a range of   paper materials   and   waterproof materials    Our standard paper is suitable for most applications but we also supply freezer paper  for frozen foods and goods   removable paper  for temporary applications   and high tack paper  for long term applications where your QR code carries vital information such as instructions or health and safety notices   Our waterproof materials are best if your QR codes are to be displayed outdoors  in indoor locations where they might get wet  or where they might be frequently handled and need to be extra durable
