DuoCash is the world's first payments processing and clearing network to enable Internet purchases through the use of prepaid phone cards. Through its partnerships with leading telecommunications companies, prepaid phone card manufacturers, and premium Internet companies, the company extends the previously inaccessible $5.2 billion stored on prepaid phone cards to the electronic payments marketplace. DuoCash is only available in the US. A lot of the top online casinos will soon be adopting this new payment method.
