Restacking the chips—pros and cons of EMV options.

Have you formed an opinion yet on the topic of chip-and-PIN versus chip-and-signature cards? Maybe you saw the recent news that many U.S. banks are leaning more toward the latter, which is less secure. I wondered about the reasons for this since other countries have already predominantly adopted the more secure chip-and-PIN. However, before diving in further, we cannot forget that any card with a smart chip and the EMV security standards is more secure than cards with only a magnetic stripe.  

On the PIN vs. signature topic, I found some great insights in an article by Brian Krebs of Krebs on Security in which he interviews industry experts from Aite Group and Gartner Inc. I highly recommend you read it, but following is a summary of two key considerations at play.

Ease of Use

Chip-and-signature takes the lead, being quicker and easier to use at the point of sale. Chip-and-PIN requires the extra step of entering the correct PIN (personal identification number). If the cardholder forgets the PIN, he or she would need to pay a different way or abandon the purchase altogether. These are not good outcomes for the card-issuing bank or your card program. 

Then there is the issue noted by Jack Jania, Gemalto Inc., during my 2014 interview with him: limitations of the current U.S. ATM infrastructure to manage card PINs in the field. Since the PIN is tied to the smart chip, it is not easy to reset. As a last resort, the bank might need to reissue the card, which is another hassle for everyone.

 

Protection for Lost or Stolen Cards

The advantage here goes to chip-and-PIN since a lost or stolen card would require a fraudster to enter the correct PIN in order to use it. With a chip-and-signature card, a fraudster could forge the cardholder’s signature at the point of sale and/or use the card at an unmanned kiosk or terminal. 

  Is it a gamble or good business decision for banks to go the chip-and-signature route? Probably a mix of both.

Given the above plus other nuances, each bank needs to decide what makes the most sense for its business. If you are an end-user organization, ensure you understand what type of card you have, requirements for usage, what could go wrong and how to resolve any issues.
