I run a decent size website that sells digital products for $10-30. We have a merchant account with Visa and Mastercard, and we also have a Paypal payment "button".
I'd like to start accepting BTC as payment, but I have 2 big questions:
1. How the heck do I know who paid me? At minimum I need an email address to send an acknowledgment and a username/password so they can download what they just bought. This is fully automated for Visa, Mastercard, and Paypal, and I expect BTC to be a manual process for a while, but I need a way to either integrate BTC into the shopping cart or have some address of the sender.
2. Have there been any dirty tricks by visa and mastercard (or Bank of America, my credit card processor) to hassle their merchants who accept BTC? I cannot afford to lose my merchant account, or have it suspended for any reason.
