What Are EMV Cards: Chip & Pin and Chip & Signature Cards

EMV stands for Europay, Mastercard and VISA. EMV cards are joint effort by these three companies to create better cards for safety of cardholders. While the regular debit cards have a magnetic stripe containing all the account information of the card holder, the EMV cards have a chip instead. The chips are harder to clone and hence the protection of cards is better when compared to magnetic strip cards. This article looks at EVM cards that are of two types: Chip & PIN and Chip & Signature cards.

EMV Credit Cards

What Are EMV Credit Cards

While the rest of world has been using EMV cards for a long time now, US has been late to adopt the cards – due to costs involved in changing the terminals that can read EMV cards. The information in cards with magnetic cards can easily be stolen by fraudsters who later use the information for own benefit by shopping or selling off the information on the darknet.

The change to EMV credit cards is happening primarily because of the massive data leaks seen at large brick-and-mortar and online retailers. Chip cards will make it nearly impossible to do anything with illegally acquired credit card numbers because of the increased security protocols.

EMV cards are also known as IC (Integrated circuits) cards as the chip is basically a firmware type chip containing the information required to conduct debit and credit transactions. As of now, the following companies provide and support EMV cards:

  1. Mastercard (includes EuroPay)
  2. VISA
  3. JCB
  4. American Express
  5. China UnionPay and
  6. Discover

With so many companies offering compatibility with the EMVs, the cards can be useful anywhere in the world. Only recently did the US ask institutions to provide chip based cards to their users. Some such institutions are American Express, Bank of America, Barclay Card, Capital One, JP Morgan, Citibank and Discover among others. You can get your magnetic card replaced or get one EMV card as an addition to the existing card, depending upon your needs.

The EMV Cards are of two types:

  1. Chip and PIN
  2. Chip and Signature

Chip and PIN Cards

To counter illegal use of cards, each transaction must be followed by some activity by the cardholder. This activity could be entering a PIN similar to the debit card PINs or can be card holder’s signature. Based on what needs to be accompanied, EMV cards are categorized into Chip and PIN or Chip and Signature cards.

A Chip and PIN card requires the card holder to enter a four digit PIN similar to the ones used in ATM with debit cards. However, not every institution accepts CHIP and PIN cards. They are better used at unmanned terminals such as parking places, automatic ticketing etc. The card holder just swipes the card and enters a print.

Chip and PIN cards are useful when there are no attendants present at the transaction terminals. Majority of other traders prefer card holders’ signature.

CHIP and Signature Cards

As evident from the name, Chip and Signature cards require the cardholders to sign on a piece of paper that comes up after a machine reads the card’s chip. Most traders prefer signature to a PIN because a signature would mean better guarantee of anti-theft cards. Where there are attendants such as the supermarkets, Chip and signature EMV cards are used more.

Most of the banks offer you the Chip and Signature card as they are more secure compared to Chip and PIN. Even Chip and PIN are secure as the data is erased from card readers as soon as the transaction is complete.

Both “Chip and PIN” and “Chip and Signature” cards increase the level of security over regular cards with magnetic strips. With EVM cards, one need not worry about data being stolen.

Merchants need to upgrade their point-of-sale (POS) terminals and ATMs. The new cards and card readers require the use of a PIN or signature. But some terminals only allow PIN authentication, rather than a signature. These sorts of terminals are common in kiosks in Europe and may grow in popularity. And it’s these terminals that won’t be able to process cards without PINs—such as our current magnetic stripe cards, says Microsoft.

    Please hold a decent tone in here.

    This article is relevant in here, and therefore not “spam”
    And you have clearly not read the article you refer to, or do not understand the “sensational tone” in that article.

    It is not possible to compromise the chip-n-pin are still secure, you have to use the four digit pin code. And therefore are this part more secure than the magnetic strip.
    I won’t start a long discussion in here, but please read the comments to the article you are linking to, and you will see many of the comments

    And finally: Kim Zettler had to make this correction on his article.
    Update 11.5.14: To add statement from Visa and to emphasize that the flaw appears only in the contactless feature of the cards.
