The three siblings, Kim, Khloe and Kourtney, have teamed up with Mobile Resource Card to bring out a pre-paid card emblazoned with their faces.
The card comes out on November 10 and Khloe admits she is very excited about the venture.
The 26-year-old star wrote on her blog: "Never thought I`d have my own face on a debit card, but I think it`s pretty amazing we`re going to be in so many people`s wallets!"
The Mastercard also comes with a free Mobile Money account - which means card holders can transfer money between their accounts using their cell phone.
Kim, 30, wrote on her blog: "To me, the coolest thing about this pre-paid card is that when you get the card you also get a Mobile Money account for free and you can transfer your money between your accounts when you need it, using your phone. It`s like having an ATM in your phone, LOL. No one likes going to banks and ATMs and we`re constantly on our phones, so why not make it easy to manage your money from your mobile!? (sic)"
The three star sisters will launch the card on November 9 with a party at New York nightclub Pacha.
Meanwhile, Khloe has revealed she was mercilessly bullied at school.
The brunette star was called "fat" and "ugly" when she was growing up and admits she would have struggled to cope with the torment if it wasn-t for the love and support of her sisters.
She said in an interview with Life and Style Weekly magazine: "Having someone in your class call you fat, ugly, too tall and so on, you start to think all those things about yourself. And, if you`re like me, those words are played on repeat inside your head.
"But when I was at home, I felt loved and safe. My sisters were always a safe haven for me. I knew they would always play with me and make me feel like I was one of them."
