Impact on sales of using external site for payment processing?
m_eiman: You should look at PCI DSS, the new requirements for processing credit card purchases. I haven't looked into it very deeply, but according to the reporting about it you'll no longer be able to use a simple form on your own site to handle credit cards - you'll have to go through an external payment processing site (or implement it yourself and have it audited - expensive!).Compliance with these new rules will be mandatory beginning next year.More info at https://www.pcisecuritystandards.org/
