QR Codes Integration with Mobile Phones

QR Codes are barcodes used for encoding information in two dimensional spaces. They were originally meant to track auto mobile parts but their popularity has grown to other broader commercial purposes. QR Codes encode data in tiny squares grid both horizontally and vertically unlike a regular barcode which encodes data horizontally alone.


The characteristic of the QR Codes of encoding data horizontally and vertically allows encoding of a lot of data in a small space. Apart from identification of products or objects, a function which regular barcodes can carry out, the QR Codes can actually embed information in a code and when that information is read with the right software, actions like triggering of a website launch or file download can occur. Another added benefit of QR Codes over barcodes is that the QR Codes can be read from any angle unlike barcodes which must be aligned properly.


QR Codes have found a wide range of applications in cell phones, especially, smart-phones and Androids. The QR Codes are tailor made for quick and simple linking to smart-phones content. They can, therefore, be put in to a lot of various good uses. A simple use on a smart-phone is magazine advertisements linking to websites. A more complex use is in start-up pingtag, which is an innovative application used to link a business card to one’s Linkedln profile. When one scans the QR Codes on the business card, they get directed to the business card holder’s profile on Linkedln, where they can find the business profile and personal information of that card holder.


For people with Android phones, QR Codes can be used to establish direct links to Android applications in the market place. Bordeaux Municipality in France has put the QR Codes into good use by placing them all over the city in a bid to track parking meters; they also guide visitors to nearby parking locations through Google maps.


To use the QR Codes on supported phones like the Smart-phones and Androids mentioned earlier, one needs to install a supporting application on the phone. There are several of these applications available in the market with QRReader, which is available freely, being a good example as well as Quickmarks, which can be downloaded by users of windows mobile phones. Some phones also come with pre-installed applications that support reading of QR Codes. Once the appropriate application is installed on the phone, one then needs to launch it and then point the camera of the phone at the particular QR Code that one intends to scan.


QR Codes are an important innovation that is bound to get even more popular, especially, with the increased popularity and affordability of mobile phones. The QR Codes can be integrated with a lot of services and mobile phone applications easing a lot of activities in the process. Apart from mobile phones, there is no limit to the number of devices with which the codes can be integrated with including computers and other devices like parking meters as illustrated by the Bordeaux Municipality in France.
