Most American Express cards are chip-and-PIN, but some use chip-and-signature technology instead. Credit cards issued by American Express all have chip-and-PIN capability, including the Amex Blue Cash Everyday, Cash Magnet, and Platinum cards. But it varies among cards on the American Express network that are issued by other banks. For example, the Wells Fargo Propel American Express Card is a chip-and-PIN credit card, while the US Bank Cash 365 Amex is a chip-and-signature card. Both types comply with EMV (Euro Mastercard Visa) standards for chip-based cards.
Chip cards are embedded with a computer chip for added security. The difference is in the cards’ verification method: the cardholder’s signature or a 4-digit PIN. Chip-and-PIN cards are more secure than chip-and-signature cards because signatures required for purchases can easily be forged, and often go unchecked. Guessing someone’s PIN isn’t so easy. Both types of chip cards still provide better protection than cards that only have magnetic stripes. That’s because chip cards are encrypted in a way that makes it nearly impossible for anyone to access the card’s information, so long as the card is inserted into a reader rather than swiped.
Most chip cards issued in the U.S. are chip-and-signature cards. Chip-and-PIN cards, however, are the standard in most other countries. But you can still use a chip-and-signature card abroad with few issues.
A chip-and-PIN credit card works a lot like a traditional debit card at an ATM. Rather than swiping a magnetic stripe credit card, you insert (or “dip”) a chip-and-PIN card into a payment terminal and follow the prompt to input your PIN. The PIN is then compared to information stored on the embedded computer chip, and the transaction is either approved or denied.… read full answer
Such transactions are the norm in many countries and are becoming increasingly common in the United States, as the country transitions to EMV payments. But chip-based cards still come with magnetic stripes because there are many places where you won’t be able to use the chip-and-PIN feature. You will have to swipe your card, like with a normal credit card.
The main difference between magnetic stripe and chip-and-PIN credit cards lies with their fraud prevention technology.
Magnetic stripe credit cards store personal financial information on magnetic stripes. Upon being swiped at the point of sale, the information contained on this magnetic stripe is cross-checked against a database of known fraudulent credit card accounts and is subsequently either approved or denied.… read full answer
Chip-and-PIN credit cards require consumers to enter a Personal Identification Number (PIN) that must match the information on a computer chip embedded within the card for a transaction to be approved.
Chip-and-pin credit cards are considered to be more secure than magnetic stripe cards. Cards with both a chip and a magnetic stripe, which is becoming the norm in the U.S., are somewhere in between.
