The Fenty administration on Tuesday backed off plans to require that District residents use a new identification credential, a card that can track a person’s use of city services, to access D.C. recreation centers.

Ward 3 D.C. Councilwoman Mary Cheh sounded the alarm, she said, after angry constituents reported they were told they would need a DC One Card to enter the new Wilson Aquatic Center. Many didn’t have or want the ID, Cheh said Tuesday. Others were concerned about the potential for privacy invasion.
