QR-Code Readers

QR-Code Readers

If you are looking to download a QR-Code reader (software) so that you can scan and read mobile barcodes (QR-Codes), you have come to the right place. We have compiled a list of the best QR-Code reading software available to download on the internet. If the QR-Code reader is not on our list, it's not worth worrying about.
Please find below available reading software and information about how to download and install the QR-Code readers.

Alternatively, if you do not have the software, you can use the following method to download it; please visit the Nokia N80 device page on the Nokia website. On the left hand menu, select 'Phone Software', then 'Smartphone'. Scroll down the page until you see 'Barcode reader'. Follow the link and instructions and you can download the software to your PC. You will then need to download the Nokia PC Suite in order to transfer the files to your mobile phone.
Additionally, if you have the download application on your mobile phone, you can use that to get the reader.


From the Nokia website, it appears that only the Nokia N80, N93, N93i, N95 and E90 support the reader. This will more than likely change as new phones are released with better image capturing software.

QR-Codes originated within the technology hungry country of Japan and have merely only recently began to become popular within the Middle East and Europe.
Barcodes that you see on any commercial product are extremely beneficial as their reading speed, supreme accuracy and their functionality are key.
As barcodes reached their peak and began getting used worldwide, the need for more data and characters types to be stored was inevitable.
Developers began tying to expand on the current amount of bars within the barcode and how their positioning to allow further data capacities. The need for smaller barcodes also was another defining factor in their development.
Such developments failed as reading and printing implications caused more problems than solutions. The 2D barcode was then born.

QR-Codes first hit mainstream when they were initially used for tracking parts by vehicle manufacturers. After a while, companies began to see the scope for where QR-Codes could be used elsewhere within the world. The most commercial use for QR-Codes is in the telecommunications industry where the mobile phone seems to be the biggest driver of their popularity.

Mobile Phones

With the technology of mobile phones constantly expanding, especially within mobile internet, QR-Codes seemed the perfect solution to quickly and efficiently bring mobile phone users onto the mobile web. QR-Codes can be used to store all kids of data including such data such as a URL (Universal Resource Locator) or as most people know them; web addresses. This then allowed offline publications such as:
  • Magazines
  • Papers
  • Business Cards
  • Buses
  • Signs
  • T-shirts
Or basically any medium that can accept the print of a QR-Code to advertise their online product which would then direct the user to the medium.

How They Work?

Take a mobile phone such as the iPhone; nearly ever mobile phone has a digital camera in today’s world. The camera, along with decoding software can be used to capture a picture of the QR-Code of which the QR-Code software decoder and then transform the data held with the QR-Code to a meaningful action for the mobile phone:
  • Connect to a web address
  • Download a MP3
  • Dial a telephone number
  • Prompt your email client with a sender address
This can all be done within a matter of milliseconds making the transformation from a user’s mobile phones browser to the mobile web instantaneous.


The Japanese standard for QR-Codes devised by Denso Wave is JIS X 0510 which was released in January of 1999. The corresponding ISO International Standard, ISO/IEC 18004, was then approved in June of 2000. The standard was then updated back in 2006. (ISO/IEC 18004:2006).

Data Capacity

QR-Codes are capable of handling of sorts of data, including numbers, alphabetic characters, Kanji, Kana, Hiragana, symbols, binary, and control codes.
A total of 7,089 characters can be encoded in one symbol alone.
QR-Code Data Capacities
Numeric only Max 7,089 characters
Alphanumeric Max 4,296 characters
Binary (8 bits) Max 2,953 bytes
Kanji, full-width Kana Max 1,817 characters

Barcodes vs. QR-Codes

Picture of Traditional Barcode
QR-Codes have become more popular than the typical barcode as the typical barcode can only hold a maximum of 20 digits, whereas the QR-Code can hold up to 7,089 characters. This makes the use and diversity of QR-Codes much more appealing than their older counter part, the barcode.
Partially part of the reason QR-Codes can hold more data, is because if you compare a typical barcode to a QR-Code, you can see one major difference; barcodes only span horizontal whereas QR-Codes can span horizontally and vertically.
Statistic – QR-Codes are capable of encoding the same amount of data in approximately one-tenth the space of a traditional bar code. Such minute QR-Codes are called Micro QR-Codes.


A great feature of QR-Codes is that you do not need to scan them from one particular angle. QR-Codes are capable of omnidirectional (360 degree’s) high-speed reading. QR-Codes scanners are capable of determining the correct way to decode the content within the QR-Code due to the three specific squares that are positioned in the corners of the symbol.
QR-Code scanner uses three corners as markers, regardless of 
pistion scanned


QR-Codes can be combined into one large symbol. One symbol can then be divided into 16 separate symbols making the data capacity extremely large.

2. രൂപയുടെ ചിഹ്നം യൂണിക്കോഡ് ഫോര്‍മാറ്റില്‍ തന്നെ ഇതില്‍ ഉള്‍പ്പെടുത്തിയിട്ടുണ്ട് .
3. ഗൂഗിള്‍ ക്രോം ഉപയോഗിക്കുമ്പോള്‍ ലില്ലക്ഷരങ്ങള്‍ " ല്‍, ള്‍, ര്‍" തുടങ്ങിയവ "ല്, ള്, ര്" എന്നിങ്ങനെ പഴയ യൂണിക്കോഡില്‍ പ്രത്യക്ഷപ്പെടുന്നത് അരുണ ഫോണ്ടില്‍ പൂര്‍ണ്ണമായും പരിഹരിച്ചിട്ടുണ്ട്.
4. യുവത്വം തുളുമ്പുന്ന നവീന ഡിസൈനിങ്ങ് ശൈലി വായനക്കാരെ പെട്ടെന്ന് ആകര്‍ഷിക്കുന്നു.
