So much for zipping through airport security for people willing to pay $199 per year and have their fingerprints and iris images scanned to be pre-approved.

Clear, the largest company to leverage the Registered Traveler program in the U.S., has “ceased operation” as of 11 pm PST today and their parent company, Verified Identity Pass, Inc., is in the deadpool. They were “unable to negotiate an agreement with its senior creditor to continue operations.” Users were notified this evening by email.

The service was popular – it was used 250,000 times at Washington, DC airports alone. Overall, the company said, over 2.5 million people were processed using Clear. It operated security lanes at 20 U.S. airports: Albany, Atlanta, Boston’s Logan, Cincinnati, Denver, Indianapolis, Jacksonville, LaGuardia, Little Rock, New York JFK, Newark, Oakland, Orlando, Reno, Salt Lake City, San Francisco, San Jose, Washington, D.C.’s Reagan and Dulles, and Westchester.
