ELI5: Why can some businesses swipe my card without any verification(PIN/signature) from me?

There is usually a threshold set by the card companies above which a signature is required. Small purchases are less likely to be fraudulent since people with a stolen card are going to run the card up as fast as possible before it gets reported. Now that cards are more common than cash, not requiring a signature for every purchase adds convenience for the consumer and efficiency for the retailer. Security is great, but it adds more work and people are always looking for that balance.
