The Pennsylvania Department of Transportation nearly has replaced more than 450,000 driver's licenses and identification cards that may have contained a defective security feature.
Most of the affected cardholders have received replacement licenses and IDs, a PennDOT spokeswoman Jan McKnight said Friday.
PennDOT began mailing replacements in early March.
"It should resolve itself fairly quickly," McKnight said. "Anybody who has one of those (defective cards), it's not crucial. It's a flaw, but it's being corrected."
PennDOT determined that between 450,000 and 475,000 licenses and identification cards issued between November and Feb. 25 may have a faulty security feature. One of the security features embedded in the laminate — and visible only by black light — was inverted in some cards.
The faulty cards display "AP" instead of "PA" when viewed by a black light.
PennDOT says affected cards may not be accepted by businesses that use black light devices to verify identification cards. But the issue does not impact Transportation Security Administration checkpoints or driving privileges.
The cards are being replaced free of charge by the vendor.
