Micro-payments

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[1] while Visa prefers transactions under 20 Australian dollars,[2] 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.[3]

One problem that has prevented the emergence of micropayment systems is a need to keep costs for individual transactions low,[4] which is impractical when transacting such small sums[5] even if the transaction fee is just a few cents.

History

Micropayments were initially devised as a way of allowing the sale of online content and were envisioned to involve small sums of only a few cents.[5] These transactions would enable people to sell content on the Internet[5] and would be an alternative to advertising revenue.[6]

During the late 1990s, there was a movement to create microtransaction standards,[5] 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.[4] The W3C has since stopped its efforts in this area,[4] 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,[5] 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,[7] 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".[8]

iPIN

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.[9] Debuting in 1999, its service was never widely adopted.[9]

Millicent

Millicent, originally a project of Digital Equipment Corporation,[10] was a micropayment system that was to support transactions from as small as 1/10 of a cent up to $5.00.[11] It grew out of The Millicent Protocol for Inexpensive Electronic Commerce, which was presented at the 1995 World Wide Web Conference in Boston,[12] but the project became associated with Compaq after that company purchased Digital Equipment Corporation.[10] The payment system utilized symmetric cryptography.[13]

NetBill

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.[14] It featured pre-paid accounts from which micropayment charges could be drawn.[15] Initiated in 1997, NetBill seems to have died completely sometime after 2005.[16]
