Developing on cash.io...
Welcome developers! We're glad you're interested in cash.io. Our job is to make your job easy.
What Problem Does cash.io Solve?
There are many payment systems that let you send money online to somebody you know. PayPal comes to mind. But how do you send money if you don't know the recipient's email address? What if you want to send payment by phone? By text message? On facebook? On twitter? And what if the recipient doesn't have an account with the payment system you're using?
cash.io makes this easy by giving you simple, easy to transfer codes that you can send out however you want. Want to send out money on twitter? Great! Want to issue refunds on facebook? Cool! Then the recipient takes the code to cash.io to redeem it. Simple as that.
