My idea is that I could create a customised QR code, show it with a sentence like "scan it to get out offers and discount". I don't want the person to land on a page with a coupon. I want to "grab" his phone number and be able to send him periodic offers.
Is this possible? How? What services do I/my clients need?
Is it possible to integrate it with the Twitter SMS free system?
I'm really sorry but I cannot find the answer anywhere. Perhaps I just did not "recognised" it, I'm not sure. It's a newbie question and I really need your help and experience!
