SCVNGR wants us to use QR Codes to pay for things

Mashable tells us that the check-in company now wants us to use our checking accounts with them (thanks Mallory Wood, for the heads up). Well more like a credit card. The system would use personal QR codes linked to a credit card to let you pay for items with retailers. SCVNGR says it would have a more immediate impact than services like Google Wallet which are “five-year plays.”

I am curious to see if these kinds of services gain any traction at colleges and universities. I have a feeling that the right one would draw a lot of interest from students who would be happy to not have to carry an ID around with them to use for dining hall meals and such. SCVNGR has good relationships with colleges already. The current test will be with 500 merchants in big cities. I wonder if a campus test run is planned somewhere and what kinds of results it would get.

When will we reach button overload?

We’ve known it was coming for a while now, but apparently Google’s +1 button is ready for wide release. Web surfers will now have another way to like, share, broadcast —whatever you want to call it— their web habits and interests to the universe.¬† The pace of adoption here will be fascinating to watch. Will this button be another useful tool for disseminating your school’s news and cool happenings or additional clutter on a web page?

Are any of you finding like +1 buttons and their ilk to be design issues? What’s your sense of how many of your web visitors are using them? In general, choice is a very good thing. However the other day I clicked on a “Share this” button and it gave me more than 250 options, most of which I’ve never heard off. The number of options were mind boggling.

Now granted, the strength of the Google brand name will give them a built in advantage in the race to share things with other people. But I’m curious if web users consider these¬† types of buttons useful or think they’re just noise. What percentage of them actually get used? Does anyone actually send something out or like a piece through say 50 services? And if that person does that, how fast are they ignored by their contacts?

What is the ideal number of “share” buttons? Somewhere out there, the happy medium lies. My gut tells me anything more than 6 starts to get annoying and 10 or more makes your page feel like this.
