Telstra QR Code excursion today

Sarah and I attended the meeting at the Telstra experience centre today. The experience, although sugar coated with Telstra propaganda, was useful in understanding how the QR code technology works and how it might be used in different contexts. 

Here are a few notes that I took:

# QR codes are created using a QR code generator. Telstra will be supplying one for customers or you can find your own on the web such as: http://qrcode.kaywa.com

# Once the code is generated you can then print out the QR code graphic or save it as an image.

# This code can be affixed just about anywhere - on the back of a credit card, to advertising, on a poster, business card etc, shopfront window etc.

# The code can be photographed with a compatible camera and is then scanned to provide TEXT information which could include a link to a website, phone numbers etc for the user.

# The codes should be, will be, international and compatible say with a phone from Japan (and vice versa). The only limiting factor is the resolution of the camera on your phone, eg in japan phones have higher resolution cameras therefore the codes are smaller whereas here they are huge. The amount of information the codes contain will also determine their size.

Hope this helps with any additional research that you may have carried out. Leisa
