These direct response technologies deliver digital content to your phone, but is sounds like a lot of steps to me. You have to take photos of bar codes and then have either downloaded an application or send a text and forward the bar code. Scanlife must use a web-enabled phone. Jagtag does not.
They are testing many potential applications. The most bizarre is to see a slide show of a loved one from a tag/barcode on a gravestone. Are you kidding!!!
I see some possibilities. How about going the other way? Let me register for coupons on my phone and then let me beam then at the store right to the cash register.
