PayPal Mobile has launched, albeit not in germany yet.
I have to disagree with Carlo’s judgement, though: the breakthrough in this isn’t that it’s mobile, it’s getting instant confirmation of a payment, thus speeding up commerce. This has been tried before with paybox and eBay in germany, and it worked just great.
Combine that with other accelerators like SemaCode to create a “point, shoot and buy” device, and you’re onto something.
Now bring it to germany, Mathias, will you?
