Does HR Need A “Customer Reward/Perks” Card?

I grabbed my car keys today and realized that I have four of those little plastic customer reward cards attached to the ring.  You know the cards, the ones you get from CVS, PetSmart, Hallmark, Borders, or other stores to incent you to come to their store.  Every time you check out, the cashier scans the card and you get points.  Once you reach a specified amount of points, you are eligible for rewards that can include cash or other discounts.

I’m not sure how popular the cards are yet with consumers, but I do notice that more and more stores are coming up with ways to “reward” you for your patronage.  I’m thinking that it would be interesting if HR practitioners operated like that.  What would the reward look like?  How would HR track the internal client patronage?  Is there software available to set up a system to recognize use of HR?  How could HR get the word out that there really is a reward in utilizing the company HR resources?

Any ideas?  Hit me with a comment and maybe we can come up with something.  Or, maybe we’ll hear that it isn’t possible or necessary.
