ELI5: How are chip-readers more secure than magnetic strips?
gpt
It's not necessarily the reader, but the card itself.   

In an eli5 sense, a magnetic stripe says "I am X" when swiped.    It is extremely easy to create a copy of the card that also says "I am X".  

A chip card, when read, initiates a conversation like "If you say you are card X, please complete this math problem using your secret ID number and give me the result".    Because the whole card's information is not transmitted during a transaction, it is much harder to create a copy.

If a second authentication factor (such as a PIN) is not used, chip cards are still weak to physical theft and malicious usage of a card, neither do they protect against fradulent online usage.
