It seems at least some on here know a bit about the company, and seem impressed by the concept at least. I know next to nothing about them, so let me give you the view of the proverbial "Joe Sixpack". Summary: I know of only one vendor that uses it, and LevelUp has to overcome my objections to using it right there at the point-of-sale.

There's one restaurant that my wife and I go to that has the POS thingy. We live in Redmond, not exactly a town full of tech-averse folk. So problem #1 is: is it worth the trouble of signing up, dealing with one more daily email newsletter (because I forgot to uncheck the box), and having to get my phone out and find the app every time we eat there? Answer: a resounding "no".

Problem #2: you have to sell me at the point-of-sale, because I frankly don't care enough to go look it up. What does LevelUp do, other than having a glowing thing that wants to have something to do with my phone? I have no idea, probably something to do with paying for my meal. If that's the only answer I can come with at the time of sale, I refer you to Problem #1.

Problem #3: I know of only one vendor in tech-savvy Redmond, WA that uses it. Why even bother to dirty my inbox and the app screen of my phone?

Problem #4: how's the user experience? Does it suck? Do rainbows and unicorns sprout from my phone when I use it? I have no idea. What I do know is that whipping out my credit card is quick and easy, and everyone involved in the transaction knows how to go through the motions. LevelUp competes against a known quantity, and that known quantity is actually pretty good.

From reading the comments, I gather that there's some kind of rewards system. Hmm, first I knew of it (see POS sales problem). Not exactly a positive for me, as I'm growing tired of loyalty cards and variations thereof.

So that's the view of a guy who knows almost nothing about LevelUp. Too much to fiddle with, and no perceived value for me.
