Barcode Labels and QR Code Labels



What Exactly is a Barcode?

A bar code can best be described as an “optical Morse code.” Series of black bars and white spaces of varying widths are printed on labels to uniquely identify items. The bar code labels are read with a scanner, which measures reflected light and interprets the code into numbers and letters that are passed on to a computer.┬áBarcodes identify products uniquely so they can be sold anywhere in the world. Lines of different widths and sizes representing data, that when read, determines what the scanned object is.

What is a QR Code?


QR stands for “quick response,” as the codes are designed to be read quickly.

QR codes are two-dimensional barcodes that can be read by many cell phones and smartphones. The codes, which are small squares with black and white patterns, appear in a variety of places, such as magazine and newspaper ads. A QR code is used to encode some sort of information, such as text or a URL.

QR codes can be read by dedicated QR code readers and cell phones that have the app. To read a QR code, your cell phone will need to take a picture of the code.



QR codes can take you to details about the company you saw advertised, you can watch a movie trailer, or be presented with a coupon.
