The Amazon Mechanical Turk team has been hard at work on a couple of important new features: credit card funding and transaction history. Both of these features are available from the Your Account page.
With the debut of credit card funding, Mechanical Turk Requesters (the people and organizations who create the HITS) can instantly add funds to their accounts using a credit or debit card or from an existing balance in an Amazon Payments account. It is no longer necessary to fund work using a bank account.
This new feature simplifies and accelerates the process of getting work done. Requesters can pre-fund their account at any level (the minimum is one dollar). Once this is done, the prepaid balance can be used to create and pay for work right away.
You now have access to your detailed transaction history from Your Account as well. You can check on your account balance and you can see the last 18 months of prepayments into your account and payments to workers. You can even download this data in CSV form.
