Episode notes
Credit Card Signatures
- You don't have to sign the back of your credit card, it's a misconception.
- It was originally for a promise to the bank, not authentication.
Signature Security
- Handwritten signatures have poor security properties and are easy to forge.
- Modern security wouldn't rely on such easily reproducible methods.
Trust in Transactions
- Trust bank tellers more than waitresses, but a robust system protects you regardless.
- Focus less on individual malfeasance and more on systemic safeguards.
