Description

From the Wikipedia:

"A micropayment is a financial transaction involving a very small sum of money and usually one that occurs online. PayPal defines a micropayment as a transaction of less than 12 USD while Visa prefers transactions under 20 Australian dollars, and though micropayments were originally envisioned to involve much smaller sums of money, practical systems to allow transactions of less than 1 USD have seen little success.

One problem that has prevented their emergence is a need to keep costs for individual transactions low,[4] which is impractical when transacting such small sums even if the transaction fee is just a few cents." (http://en.wikipedia.org/wiki/Micropayment)
