It sounds clunky, although Cha! plays down the hassle of charging up multiple online payment accounts by suggesting that it's no different to the way consumers typically have several different credit, ID, local transit and Ezpass cards.
Cha! says it charges between 8% and 20% per transaction and is aiming 1ClickCharge at the market for transactions under $20.
1996 start-up Cha!'s $1.5m angel funding came from the same Israeli backer of Mirabilis Ltd, which sold its ICQ internet chat and messaging system to America Online Inc for $287m last year.
