Although radio-frequency identification, or RFID, systems are attractive to retailers looking for ways to track merchandise, provide a quicker transaction and offer new payment methods, they appear to be fizzling with consumers, at least locally. For two years, ExxonMobil's Speedpass, the nation's largest system, and other RFID programs have been available in the Triangle. Analysts say many consumers are unwilling to dangle something else with their keys and uninterested in adopting yet another way to pay -- especially one that doesn't feel secure. At the gas station, it's almost as fast and easy to swipe a credit card at the pump. Plus, not many consumers are even aware that the program exists.
