QR Codes or Quick Response Codes are graphical representations of data. They are very much like barcodes but they contain much much more. Here are 9 free QR code generators for you to use in your next web project.
Nowadays, they can be seen everywhere and in myriads of aesthetic variations. However, they exist for one purpose and one purpose alone: data storage. Among others, QR codes contain (1) website URLs that trigger browsers to go to the encoded web addresses; (2) phone numbers and business cards that automatically get stored in mobile phones; and (3) inventory codes that let business owners track and manage assets.
A QR Code is easy to read. It does not require any specialized equipment to capture its encoded content. It only needs a computer and a web camera. In this regard, any smart phone, laptop, or tablet with a QR Code reader App can be used. Moreover, QR Codes contain more data than the standard UPC barcodes. Further, and most importantly, QR Codes can be read faster than traditional encoded badges.
It is one thing to read, but quite another to generate. No worries! QR Code generator services are provided free online. And they do the job fairly well. Some have options that will automatically let you interface with: (1) Website URL; (2) YouTube Video; (3) Google Maps Location; (4) Twitter; (5) Facebook;(6) LinkedIn; (6) Instagram; (7) FourSquare; (8) App Store Download; (9) iTunes Link; (10) Dropbox; (11) Plain Text; (12) Telephone Number; (13) Skype Call; (14) SMS Message; (15) Email Address; (16) Email Message; (17) Contact Details; (18) Digital Business Card Event (VCALENDAR); (19) Wifi Login (Android Only); and, (20) Paypal Buy Now Link.

In a sense, QR Codes have facilitated ‘real world computing’ by providing a physical connection between our real and digital selves.
“The QR code system was invented in 1994 by Denso Wave. Its purpose was to track vehicles during manufacture; it was designed to allow high-speed component scanning. Although initially used for tracking parts in vehicle manufacturing, QR codes now are used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile-phone users (termed mobile tagging). QR codes may be used to display text to the user, to add a vCard contact to the user’s device, to open a Uniform Resource Identifier (URI), or to compose an e-mail or text message. Users can generate and print their own QR codes for others to scan and use by visiting one of several paid and free QR code generating sites or apps. The technology has since become one of the most-used types of two-dimensional barcode.”
