Most banks require that you input your social security number in order to access your bank account. For anti-fraudulent and preventative measures Stripe, our third-party service for handling all payment and withdrawal processes, also requires your social security number.
This is done to ensure the safety of the Gameflip Marketplace.
We do NOT store any bank or credit card information you input into Gameflip. All of our transactions go through Stripe, a trusted payment processing company.
