QR Code

A QR co

de (a

bbreviated from Quick Response code) is a specific matrix barcode (or two-dimensional

code) that is readable by dedicated QR barcode readers and camera telephones. The code consists of

black modules arranged in a square pattern on a white background. The information encoded may be

text, URL, or other data.

QR Code Example

UPC-A

Each UPC-A barcode consists of a scannable strip of black bars and white spaces, above a sequence

of 12 numerical digits. No letters, characters, or other content of any kind may appear on a standard

UPC-A barcode. The digits and bars maintain a one-to-one correspondence - in other words, there is

only one way to represent each 12-digit number visually, and there is only one way to represent each

visual barcode numerically.

The UPC-A barcode is used on retail goods.

UPC-A Example

1 2 ... 46 47 48 49 50 51
