QR Code: Best Innovation In Data Storage

The brilliant invention of bar code resulted in an amazing advantage due to its 3 advantages of reading speed, accuracy, and superior functionality characteristics. This method of coding dominated the market and the demand for codes capable of storing more information, more character types, and that could be printed in a smaller space increased. The developers involved in various efforts to increase the amount of information stored by bar codes, such as increasing the number of bar code digits or layout multiple bar codes in that little space.

The successor to normal bar codes was the QR code.  QR Code (which looks like the given image) is a kind of two-dimensional symbol that is easily interpreted by scanner equipment. QR Code (2D Code) holds information in both vertical and horizontal directions, whereas a bar code contains data in one direction only. QR Code holds greater volume of information than a bar code.

The products team of Contus Support has been rigorously working for quite some time now and has successfully incorporated the QR code facility for its iPhone apps such as Groupclone, IndEmergency etc. The Ind Emergency is a free iPhone app from Contus Support which is a very useful application for all users residing in India. They can install IndEmergency for free by showing their iPhone’s photo lens at the below QR code for IndEmergency.

Customers who wish to buy the GroupClone to create their own unique Group Buying Site as an iPhone app can, for a preview, install the GroupClone iPhone app for free by using the corresponding QR code.

The new idea the Products Team is currently working on: As usual the customer who has acquired coupon (consisting of QR code) from a deal site goes to the respective shop to buy the product. The shopkeeper can scan the QR code in the coupon, by which the database will be updated with this coupon number and hence fraud re-using of the coupon can be easily detected. This innovative usage of the QR code helps to avoid errors and also save time in making sure that coupons are not re-used.

The QR code is very common in Japan market. QR is the abbreviation for ‘Quick Response’ since it allows contents to be decoded at high speed. It was created at Toyota subsidiary Denso-Wave in 1994.

    Hi Mario,

    This is Arthika. Thanks for your response and interest on our product.

    The Iphone will not have the same template and language which you have it in the website.
    But we need to integrate the same design and language into the iphone apps also separately.

    Looking forward for your response.

    With Regards,
