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 while 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 the emergence of micropayment systems is a need to keep costs for individual transactions low, which is impractical when transacting such small sums even if the transaction fee is just a few cents.

Micropayments were initially devised as a way of allowing the sale of online content and as a way to pay for very low cost network services. They were envisioned to involve small fractions of a cent, as little as US$0.0001 to a few cents. Micropayments would enable people to sell content on the Internet and would be an alternative to advertising revenue.
During the late 1990s, there was a movement to create microtransaction standards, and the World Wide Web Consortium (W3C) worked on incorporating micropayments into HTML even going as far as to suggest the embedding of payment-request information in HTTP error codes. The W3C has since stopped its efforts in this area, and micropayments have not become a widely used method of selling content over the Internet.
Early research and systems
In the late 1990s, established companies like IBM and Compaq had microtransaction divisions, and research on micropayments and micropayment standards was performed at Carnegie Mellon and by the World Wide Web Consortium.
IBM Micro Payments
IBM's Micro Payments was established c. 1999, and were it to have become operational would have "allowed vendors and merchants to sell content, information, and services over the Internet for amounts as low as one cent".
An early attempt at making micropayments work, iPIN was a 1998 venture-capital-funded startup that provided services that allowed purchasers to add incremental micropayment charges to their existing bill for Internet services. Debuting in 1999, its service was never widely adopted.
Millicent, originally a project of Digital Equipment Corporation, was a micropayment system that was to support transactions from as small as 1/10 of a cent up to $5.00. It grew out of The Millicent Protocol for Inexpensive Electronic Commerce, which was presented at the 1995 World Wide Web Conference in Boston, but the project became associated with Compaq after that company purchased Digital Equipment Corporation. The payment system employed symmetric cryptography.
The NetBill electronic commerce project at Carnegie Mellon university researched distributed transaction processing systems and developed protocols and software to support payment for goods and services over the Internet. It featured pre-paid accounts from which micropayment charges could be drawn. Initiated in 1997, NetBill seems to have died completely sometime after 2005.
The term micropayment or microtransaction is sometimes used to the sale of virtual goods in online games, most commonly involving an in game currency or service bought with real world money and only available within the online game.
Recent micropayment systems

PayPal MicroPayments is a micropayment system that charges payments to user's PayPal account and allows transactions of less than US$12 to take place. The service is, as of 2013, offered in select currencies only.
Bitcoin and other cryptocurrencies
Bitcoin enables payments of very small sums (for example less than $1) with negligible cost. Bitcoin is operated without a centralized authority, and enables both large payments and micropayments. One downside of Bitcoin is the unstable exchange rate of Bitcoin vs. traditional currencies. In addition, several other similar cryptocurrencies exist.
