Well, the most important reason for safety is "exemption from liability", which exempts the cardholder from liability and the risk is borne by the card company. Like I said in your other post.

The teller occasionally checks the cardholder's ID, but the signature cannot be compared at all.

It is not certain that debit cards are safe. In the United States, credit cards are basically used. Sometimes, debit cards are also treated as credit cards and can be used without a password. transaction (my friend encountered this when we went to California. I have never understood how this happened), and often there is no "exemption" from debit cards.

So, debit cards are not necessarily safe.
