What are the limits on content pricing?
While there are no real limits to how high or low a price Pico-Pay can handle, it makes business sense to only use Pico-Pay as a payment gateway for content which falls below the lower threshold of viable credit card payments, namely around US$5. It also makes little sense to use Pico-Pay for content which costs less than perhaps US$0.20, as banner ads can pay for this level of revenue.
