Vivienne Tam limited edition Square payment device

Twitter co-founder Jack Dorsey’s tiny Square payment system is quite useful, since it allows folks to accept credit card payments via smartphones while on the move. That being said, how often do you see those mobile payment solutions get the fashion treatment? Well, the Square payment system has just gotten some loving from Vivienne Tam, the fashion designer that has collaborated with HP on special edition products in the past and this time she has come up with a special edition version of the tiny device. The limited-edition Square device will be sold exclusively through Tam’s website and will set you back $10, which could probably qualify for an impulse purchase.
