While other gift cards and vouchers are redeemed to an account affiliated with the store the card is for, such as an iTunes or Google Play, Karma Koin ... works a little differently. You do not need to create an account like the others. Think of Karma Koin more like a prepaid Visa or other credit card. When you purchase a Karma Koin, you are exchanging your cash for digital currency to be used at the place of business of your choosing. This allows you to provide payment for goods and services without the use of your credit card. In addition to this convenience, Karma Koin also donates 1% of each purchase to charities to promote positive change around the world!
