What's in your wallet may not be the most secure, antifraud credit card available.
A new study of credit cards from 25 of the largest issuers found that many still fall short of protecting users from fraud.
The report, released by Javelin Strategy & Research, a Pleasanton, Calif.-based financial services research firm, found that
while almost all card issuers do well in helping their customers after fraud or theft occurs, many need to upgrade their identity
fraud detection tools.
Among the key deficiencies:
* 56% of the 25 card issuers surveyed continue to require full Social Security numbers to help identify their customers, whether
by phone, online or by mail. "This is a risky practice that unnecessarily increases the customer's exposure to identity fraud,"
the report states.
* Consumers are not allowed to set transaction limits or block certain types of transactions using their credit cards, such
as restricting card use to purchases only made with U.S. vendors, according to the study. In fact, only 24% of the surveyed
card issuers allow consumers to set so-called user-defined limits and/or prohibitions (UDLAP) on their accounts to help prevent
unauthorized use, the study concluded.
* While more card issuers now offer consumers e-mail or telephone "transaction alerts" to advise them of account activity,
the number of participating card companies is still small -- about 8%.
Not all of the news is bad, however.
Customers do appear to be safer logging into their accounts online than they have been in the past, because of the widespread
use of multifactor login processes, which require a username, password, identifying information such as photograph placed
by the user and a correct answer for a challenge question, according to the study. More than 80% of the surveyed card issuers
are now using authentication processes with a multifactor approach.
The Javelin report rated the card issuers using three criteria: prevention, detection and resolution. The top safety scorecard
honor went to Bank of America's Visa Platinum card, which received 69 out of a possible 80 points, earning high marks for
prevention techniques. The American Express Blue card finished second with 66 points, winning high ratings for detection protections
for cardholders.
Two card issuers tied for third place with 64 points each -- the Discover Platinum Card and First National Bank Omaha's Platinum
Edition Visa Card.
Rachel Kim, a Javelin risk and fraud analyst who wrote the study, said credit card security continues to evolve. "We're seeing
that issuers are always going to be doing a great job in resolution," she said. "But detection is where they need to amp up
their efforts."
The continued use of easy-to-steal and easy-to-obtain Social Security numbers as identification criteria by credit card issuers
is "pretty scary," Kim said. "They don't have any need to use the entire Social Security number. They can just use the last
four digits. It's just something they have been doing for so long. I am sure that over the next few years we will see a decrease
in usage."
