Engadget reports that Skype is adding Pre-Paid as a way to top off, making them look more and more like a mobile operator. They're retailing Pre-Paid cards at a slew of technology and consumer shops across the UK, much like they are already doing in Mexico.
What this means is those without credit cards, or those who wish to create a disposible account can easily do so. Think about "burner" phones that one buys at Wal*Mat from Tracfone. Now, the same crowd that needs them in the UK can set up a disposable account on Skype, pay for it using a pre-paid card, and shut the account down. Basically, this adds a new wrinkle to annonymous account creation and at the same time opens up Skype's more advanced services like Skype IN and OUT, multi-party video and more to the unbanked or crowd that doesn't want to use a personal credit card for business use.
