QR Codes are basically a barcode, but unlike bar codes due to it vertical and horizontal squares can hold more data.  QR codes can actually embed that information in the code itself, and, when read with the proper software, can trigger actions like launching a website or downloading a file. Additionally, QR codes can be read from any angle, while barcodes must be aligned properly.

So what exactly can I do with QR codes?

QR codes are tailor-made for quickly and easily linking to content on smartphones. Simple uses include magazine advertisements that link to websites. Putting the codes to more complex use, start-up Pingtag uses them as a sort of digital business card for sharing LinkedIn accounts and contact info. Android uses QR codes to link directly to apps in the Android Marketplace, and the municipality of Bordeaux, France has posted them all over the city in order to track parking meters, provide links to information from the World Heritage Foundation and guide visitors to nearby shops or parking locations via Google Maps. In turn, Google has been using QR codes to promote local businesses (and itself) with the Google Places business directory, which includes reviews, contact info, and, if the business so wishes, coupons, as well f you want to to make your business grow faster you can do it by gaining more followers but how to get TikTok followers?

How can I use them?

There are a number of apps in the iPhone App Store that can read QR Codes, including the free QRReader. Most Android phones and BlackBerries are able to read the codes right out of the box, as can newer Nokia handsets. Windows Mobile users can download QuickMarks. All you need to do is launch the appropriate app, and point your phone’s camera at the QR code you want to scan.

QR codes are only bound to become more common in the coming months and years. We’re increasingly reliant on our mobile devices, and typing out URLs or other data on their tiny keyboards is still not very efficient. These squares of elaborately arranged boxes are a shortcut around that problem, can easily be integrated with various services, and incorporate geo-location data. Advertisers may not have figured it out just yet, but QR codes are their best friends.
