WAON

is Japanese electronic money introduced by ÆON from April, 2007. It is a rechargeable contactless smart card. Like many other smart card systems in Japan, it uses RFID technology developed by Sony known as FeliCa. Its name comes from , meaning harmony. The card's official mascot is a white dog. The card reader is said to makes a "waon" sound upon successful transaction, a Japanese onomatopoeia for dog barks.

It is often compared against their rival's card nanaco by Seven & I Holdings, which owns 7-Eleven Japan and Ito-Yokado. Unlike nanaco, the basic WAON Card can be purchased without any registrations. Like other FeliCa-based systems, WAON has a mobile payment system, known as Mobile WAON.

According to Nomua Research Institute, as of April 2008, there were approximately 4.2 million WAON users with around 25,000 participating stores.
