Byron Tau of Politico writes that the Obama campaign will be taking payments via mobile payment system Square. This is a very good idea, Mr. President. This way, people at rallies, town halls, and other large gatherings of supporters can give as little or as much as they want. It's all handled via mobile phones and tablets, and Square's card-swiping dongle. Of course, I guess the real question is whether people will be comfortable swiping their credit card via a mobile phone and whether they will trust that their money is truly going to President Obama's campaign and not to some Democrat-hipster's bank account.
