>You can ask to see the receipt that you signed in case of fraud.
I understand that's how it's supposed to work, but what does the signature accomplish in practice? If anything, a "signature" that even contained recognizable letters, much less anything that looked like my name, would be a sure sign of fraud, because I never enter anything that resembles a real signature.
Most justice systems have a practice of verifying signatures of documents. I believe it's generally based on comparing the disputed signature to a body of your regular signatures and, in contentious cases, handwriting experts.
I'm not sure how it would play out in court if you intentionally make random unattributable scribblings each time. Sounds like something that might be seen as intentional obfuscation.
