What potential pitfalls should be considered when choosing an e-payment provider for virtual goods?

One potential pitfall to consider when choosing an e-payment provider for virtual goods is the security of the payment process. It is important to ensure that the provider has robust security measures in place to protect both your customers' sensitive information and your business from fraud. Additionally, consider the fees associated with using the provider, as high transaction fees can eat into your profits.

// Example code for checking the security of an e-payment provider before integrating it into your website

// Make sure to research the provider's security measures and reputation
$provider = "example_provider";
if($provider == "example_provider"){
    echo "This provider has strong security measures in place.";
} else {
    echo "Proceed with caution, further research is needed on this provider's security measures.";
}
