The reason for the success of mobile tagging, besides the flexible and multiple fields of application, is the quick, precise and customer-driven access to information. According to the principle of physical world connection (see also Object hyperlinking), the user is able to gather digital information immediately by scanning a two-dimensional barcode, like one on an advertisement.
In Europe mobile tagging is now gaining traction, albeit that the primary usage has been direct linking of URLs to 2D codes. Indeed, several campaigns in relation to physical world connection have been launched, however a standard for multi-dimensional barcodes is still missing.
One of the key organizations driving wider implementation of two-dimensional barcodes is GS1 / GS1's main activity is the development of the GS1 System, a series of standards designed to improve supply chain management. The GS1 System is composed of four key product areas: Barcodes (used to automatically identify things), eCom (electronic business messaging allowing automatic electronic transmission of data), GDSN (Global Data Synchronisation Network which allows partners to have consistent item data in their systems at the same time) and EPCglobal (which uses RFID technology to immediately track an item).
The reader uses the camera of a mobile phone for the mobile tagging process. The producers of the reader are very involved in developing solutions to increase the number of compatible mobile phones. Most services on the corresponding websites offer the download directly onto the mobile device or PC. In addition, many providers offer the user a generator for creating their own codes.
Smartphone cameras can be used in Google's mobile Android operating system via both their own Google Goggles application or 3rd party mobile tag readers. Nokia's Symbian operating system features a scanner which can scan mobile tags, while mbarcode is a reader for the Maemo operating system. In the Apple iOS, a mobile tagging reader is natively included in the iOS 11 update through the camera app, although there are more than fifty paid and free apps are available with both scanning capabilities and hard-linking to URI. With BlackBerry devices, the App World application can natively scan mobile tags. Windows Phone 7.5 is able to scan tags through the Bing search app.
Due to the absence of a standard code, the readers are faced with the same problem. On the one hand there is a remarkable number of readers which aren't able to identify barcodes apart from their own proprietary codes. On the other hand, there are several readers which were created to read out non-proprietary code, these 'open source codes' are the most used for Optical Reading with Mobile like the QR Code and the Data Matrix. However, a QR code is always 60% larger than a DataMatrix code and this tends to mean that DM is the primary code used in packaging and enterprise solutions for example.
The first company used QR Code for IT Asset Inventory Tagging System was initiated last October 11, 2012 made by Castlewood Group Pte Ltd Singapore led by IT Manager, Engr. Men-She-Vik P. San Diego, MIT. This unique concept innovates the use of QR Code as a medium for proper handling and monitoring of IT devices and peripherals for this company. Earlier concept made by other companies with the help of bar code tagging technology for IT asset inventory but now with the latest technology of encrypting and decrypting of information, QR Code may consider as one of the best application to manage IT asset of the company.
Furthermore, barcodes allow services like saving data automatically in the contact list of mobile phones by scanning a code printed on business cards.
In addition to higher user friendliness, private tagging offers novel opportunities for self-presentation.
