QR Codes Workshop – What Are QR Codes? What Do They Do?

QR codes, short for Quick Response, are a type of two-dimensional barcode, readable by dedicated QR barcode readers and camera phones.They consist of black modules arranged in a square pattern, with an equal number of rows and columns, on a white background. This text can be anything, such as a website address, contact information, a telephone number, or marketing information. As QR codes are squares, there are a fixed set of QR code sizes: from 21 to 177 rows and columns, increasing in steps of four. Each configuration is called a version. The more rows/columns, the more data the code can store, up to 4,296 alphanumeric characters of text.

QR codes, also known as hardlinks or physical world hyperlinks, were created by Toyota subsidiary Denso-Wave in 1994, originally to track parts in vehicle manufacturing.

There are many QR code readers available for smartphones, including:
iPhone: QR Code City
BlackBerry: NeoReader
Android: QR Droid

To learn about how you can use QR codes on your website, come by our office on Friday April 15 at 11 a.m. for a workshop. Afterwards, join us for cake to help celebrate our 10th Anniversary.

Scan this code with your QR code reader, or learn more about them from Wikipedia and Google.
