I am working on an e-commerce website and I'm looking for a user-friendly means for the customer to affirm agreement (sign). I really don't want to subject potential customers to printing the form from the internet, signing it, and faxing it back. Having gone this route myself before, I don't want to subject the customer to this hassle and delay.
The only thing I have come up with is services that offer "digital signatures" or whatever, but honestly, even though I have an engineering degree I do not understand all the stuff about millions of bits of encyption, public keys, and other gibberish. I'm not really sure what they are or what they do, but it certainly isn't a signature (as nearly as I can tell). I just want something that produces a real graphical signature online, maybe something like a point-of-sale terminal at the supermarket. Does anyone know of any script or widget that could do this?
