NO CASH DAY™, the first international event against cash.

At first I thought this was satire:

They are proposing a day that you not touch bills or coins because, oh ...
  well paper money has Staphylococcus bacteria, and cocaine.  
  And coins -- some people are allergic to them!

Then look at the sponsors:

  VISA / MC / AMEX, Smart Card Alliance, etc.

Is this to help stave off a resurgance in hard currency?

Nothing says Bitcoiners can't join in on the boycott.  Just use bitcoins instead.

From the same people who brought you mussolini yay!!
