Mobile bar code - QR code
A QR Code is a matrix code or we can say that it is a two-dimensional bar code which is created by Japanese corporation Denso-Wave in 1994.
QR--> Quick Response , it is intially used to trap tracking parts in vehicle manufacturing .QR Codes storing addresses and URLs may appear in magazines, on signs, buses, business cards or just about any object that a user might need information about. A user having a camera phone equipped with the correct reader software can scan the image of the QR Code causing the phone's browser to launch and redirect to the programmed URL. This act of linking from physical world objects is known as a hardlink or physical world hyperlinks .ck parts in vehicle manufacturing.
Capacity of QR code
- Numeric only --->Max. 7,089 characters
- Alphanumeric---> Max. 4,296 characters
- Binary (8 bits) --->Max. 2,953 bytes
- Kanji/Kana---> Max. 1,817 characters
This QR code allows you to send greater character at a time as compare to sms. This QR codes is commonly used in Japan regularly for a range of services like
- flight boarding pass
- membership and purchase discounts at cafes and bars
- travel renewals &ID .
In Nokia N93, N93i, N95 or E90 you will find a barcode reader preinstalled on your device, ready to scan mobile codes around you.

mobile bluetooth security
There are few tips to improve your bluetooth security.
- Set your Bluetooth to "non-discoverable" ie. hidden.
- PIN Code must be strong.
- Paring must be secure which means pairing of your bluetooth devices must be in secure places. Pairing must not be done in public places.
- Do not store any important data such as credit card , Atm card no. & their password in your mobile.
- Stay up-to-date on Bluetooth developments and security issues, and regularly check with the manufacturer of your device for news on software updates or any specific security vulnerabilities.
Mobile Virus History...
A mobile virus is an electronic virus that targets mobile phones or wireless-enabled PDAs.
The first ever computer virus spread by mobile phones has been sent to anti-virus firms.
A mobile virus is The first instance of a mobile virus occurred in June 2004 when it was discovered that a company called Ojam had engineered an anti-piracy Trojan virus in older versions of their mobile phone game Mosquito. This virus sent SMS te
xt messages to the company without the user's knowledge. This virus was removed from more recent versions of the game; however it still exists on older, unlicensed versions. These older versions may still be distributed on file-sharing networks and free software download web sites.
xt messages to the company without the user's knowledge. This virus was removed from more recent versions of the game; however it still exists on older, unlicensed versions. These older versions may still be distributed on file-sharing networks and free software download web sites. When the infected file is launched the mobile phone's screen displays the word "Caribe".
In July 2004, computer hobbyists released a proof-of-concept mobile virus named Cabir. This virus replicates itself on Bluetooth wireless networks.
In March 2005 it was reported that a computer worm called Commwarrior-A has been infecting Symbian series 60 mobile phones. This worm replicates itself through the phone's Multimedia Messaging System (MMS). It sends copies of itself to other phone owners listed in the phone user's address book. Although the worm is not considered harmful, experts agree that it heralds a new age of electronic attacks on mobile phonesan electronic virus that targets mobile phones or wireless-enabled PDAs.

Turn your phone into a projector
Mobile devices can store pictures and videos, but viewing them on such a small screen isn’t ideal. Microvision, based in Redmond, WA, hopes to solve this problem with a microprojector the company plans to reveal at next year’s Consumer Electronics Show. The system, composed of semiconductor lasers and a tiny mirror, will be small enough to integrate into a phone or an iPod, says Randy Sprague, chief engineer at Microvision.
Right now there is great interest in putting projectors in phones. Indeed, major phone manufacturer Nokia is “looking at” different technologies to integrate projectors into mobile devices (see “The Future of Cell Phones“). As the fabrication technology used to make the components of these projectors matures, it is becoming more economically feasible to create a projector small enough to fit into a handheld device, says Microvision’s Sprague.
So you like the idea of watching TV or movies on your MP4 player or cell phone, but the screens are just too small for you to make an accurate call on instant replay, especially if your next paycheck is on the line with the game’s outcome. All that could change with new technology from Microvision, which claims to have built the world’s smallest projector.

Accessory Projector with PicoP display engine
An accessory pico projector turns photos, videos, and other content into big viewing experiences that can be shared with others. Projected content is delivered to the accessory projector from common video out connnections on cell phones, personal media players, laptops, digital cameras and other mobile devices. Accessory projectors leverage Microvision's PicoP display engine which at its heart, contains Microvision's patented MEMS scanner. Other technology components include, laser light sources, optics, and electronics. These components are brought to life using Microvision’s proprietary software and expertise.
