Micropayments refer to small financial transactions, often less than a dollar, conducted online. They have gained prominence as a way to monetize digital goods and services that are too inexpensive to be effectively priced using traditional payment methods. For instance, a website might charge a few cents to read an article, or a mobile game might offer in-game purchases for small sums of money. Micropayments are generally designed to be quick and frictionless, allowing for an efficient exchange of value without the need for complex processing or high transaction fees. By enabling these smaller transactions, micropayments open up new revenue streams and business models, particularly for content creators, app developers, and other online service providers.
