In March, the Department of Homeland Security announced that passengers must have a REAL ID to board domestic flights without a passport. Created in response to the 9/11 attacks, the REAL ID Act sets stricter standards for state-issued IDs, raising the bar on identity verification to bolster national security. Applicants must present documents to prove their identity, legal presence in the U.S., Social Security number, and address. This reduces the chance of fake IDs or identity fraud. Now the TSA is shutting down a popular hack that’s happening at airports around the world — air travelers attempting to use their Costo cards as valid ID. The TSA took to Facebook this week to make it clear that a Costco membership card cannot act as a substitute for a REAL ID. “We love hot dogs and rotisserie chicken as much as the next person, but please stop telling people their Costco card counts as REAL ID because it absolutely does not,” the agency wrote. Needless to say, the comments on social media were hilarious, with one commenter writing: “What’s more American that using a card that gives you access to hot dogs?” Another chimed in, “Do you take Uncle Sam’s Club card, though?” The TSA specified that acceptable alternatives to a REAL ID are limited to a valid passport, passport card, or Department of Homeland Security trusted-traveler cards Global Entry and Nexus. Those who don’t have a REAL ID can still obtain one through their local DMV.
