Detecting Cloned Cards at the ATM, Register

Recent research conducted at the University of Florida has found that many bank and gift cards that are cloned have a greater variance in digital bit placement on a card's magnetic strip. This is likely due to cloned cards being created by hand with inexpensive encoding machines contrary to legitimate cards which are created in automated and machine driven processes. The University of Florida tested a new technology that can be incorporated into point-of-sale systems and can detect legitimate from cloned gift cards with 99.3 percent accuracy. This still leaves the possibility of the system to flag a "false positive" result. However, with further testing the technology was able to detect a cloned bank card with "virtually zero false positives" due to the variation in the magnetic strip on counterfeit cards. Until chip readers are 100 percent adopted across all platforms, this type of fraud will be an issue for businesses. To mitigate this sort of fraud, businesses and consumers are urged by the FBI to use and look for sealed cards in stores and store cards behind counters with limited access. Banks are encouraged to make the transition to chip embedded cards due to their improved security. Educate customers and ensure employees are also trained on stop loss.
