Waon is a Japanese electronic money system introduced by ÆON in 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 chord. The card's official mascot is a white dog. The card reader makes a "waon" sound upon successful transaction, a Japanese onomatopoeia for dog barks.
Unlike the nanaco card issued by Seven & I Holdings, 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.
