Mis-redemption is exactly the same as for normal printed coupons: i.e.. you
have to trust your retailers. The bigger problem is differentiating between
first-time users and repeat users of the coupons. The simplest way is to put
a unique ID on each coupon to be printed out. This doesn't stop people
redeeming re-prints, but allows you to track how many real different
customers used the coupons. You'd also want unique IDs on there so you can
corellate online demog info to redemption info.

There are two big ones, Digimarc and Digital Convergence Cue-Cat. Both
Merkin, both doomed (imho). They seem to base their business model on the
fact that the thing stopping people looking at webpages is that urls are
hard to type in. So instead, you'll have to get new technology working on
your computer, install their software, and start waving your magazines in
front of your computer.

every day, computers are making people easier to use
