What Is Chip and PIN Authentication?

Remember, that PIN works like your debit card. You’re required to enter it when you go to make a purchase. That helps prevent people from stealing your physical card and using it to rack up fraudulent charges. If they don’t have the PIN, they probably can’t use the card — even if they have the card in hand. When given the option, make sure you opt for chip-and-PIN cards over chip-and-signature cards. The PIN is what stops people who may take your actual card and use it without your authorization.
