I've used PayPal for a few years now and like the service very much. Their bank account registration is really very good and quite secure. During the registration process, they actually make a very small deposit into your account. To complete the registration process, you have to check your account and report back to them the exact amount of the deposit. That way they are assured anyone signing up for bank transfer actually has access to the account they're registering.

I've used it just to send money to people via email as well as eBay and other online purchases. I'ts far and away my favorite way to pay online.
