SEMA and QR codes

Take a photo with your phone and the camera software will read the QR barcode

Scan the code!
Tourists walking around San Francisco last spring found a new way to locate the best food in the city: small images that looked like bar codes, adorning more than five hundred restaurants and businesses. When the codes are scanned with a digital camera enabled smartphone, they provide instant access to Citysearch reviews and other Web-based content. But this is only the beginning of what these codes can do, according to Jonathan Bulkeley, chief executive officer of Scanbuy, the developer of the ScanLife bar codes that were plastered all over the City by the Bay.

You will be able to walk past fruit at the supermarket, scan an apple, and see when it was picked and where it came from, says Bulkeley. While buying hair dye, you will be able to scan the code on the signage and see instructions. You can create your own code, put it on a T-shirt, and then let people scan your shirt and link directly to your MySpace page.

QR or Semacode?
SemaCodes are an opensource version of QR (Quick Response) codes which are huge in Japan. Technically, a semacode is an optical barcode that contains a URL internet address. Practically speaking, it's a system that allows you to build applications that connect the real world with the virtual. A user can scan a semacode tag and then with a single click connect to the web page or other internet resource right on their portable camera phone.

QR code
A QR Code is a matrix code (or two-dimensional bar code) created by Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed. QR Codes are common in Japan, where they are currently the most popular type of two dimensional codes. Moreover, most current Japanese mobile phones can read this code with their camera.
