A 2D Barcode is easily generated and can be used for a variety of purposes, the most common - and perhaps most useful - of which is to contain a URL so that clients can quickly access more information without having to type in long strings of text.
Phones increasingly have the scanning software on board, but otherwise it can be downloaded from such volume suppliers as i-nigma.
If you use SMS campaigns, you can set a 2D barcode to enter the number to respond to in an SMS, as well as any keyword or code into the text field, so an interested participant can just scan the code and click "send".
We also recommend creating a 2D bar code of your business card details, and putting this on to the reverse side of a business card: when scanned, it can be instantly imported into an address book such as Outlook.
