Just as an FYI, it's not a bar code, it is a QR code.
So I found some cool things about this QR code scanning. It's using the ZXING platform from google which is really good. But something cool is that they didn't remove some of the scanning features.
It still has the ability to recognize the following and give you options.
BBM - Obiously add a BBM contact.
URL - Asks you if you want to open the URL and will in the browser.
Phone Number - Gives you the option to call the number.
Geo Location - Lets you open the location in the Blackberry Maps app!
Email - Opens a compose email to the email address encoded in the QR code.
You can test these out using the zxing QR code generator here QR Code Generator
A tad annoying that I'd have to go into BBM and add new contact, then to the scanning just to get to the scanner. I really hope they just add in a built-in QR code scanner application soon! PLEASE RIM, you're almost there! :D
