PayPal Here
Paypal have launched a competitor to Square. Neither are available in the UK, so I don't care that much, but they're an indicator of the future, and it's good to see competition in this space. Although frankly, I think you'd have to be mad to try and run a serious business with Paypal, given their oft-demonstrated willingness to simply seize their users assets for spurious reasons like "we thought you were making too much money".
