Somebody should make the call or send the email.
The Front of the Postcard is the Agency's job.
The Back of the Postcard is a QR code, a tinyurl, and/or a message from one of their sponsors. Starbucks is the natural. They could distribute them at the stores, embed location information, then get the use patterns in real time. The sponsor gets the metrics they need. They could pay MSNBC by click.
Click and watch the video. On the computer or the cell phone. Then harvest the incoming data from CodeZ QR.
