There’s a new way passengers are trying to bring weapons onto planes! KCCI’s Kim St. Onge is LIVE at the Des Moines Airport with how people are doing this and what’s being done to stop it. These weapons kind of resemble this credit card…except they’re a little thicker and a very sharp blade slides out from the side. Here’s what they look like. In most cases the cards are black and can be folded to make it smaller. They’re a fit easily into a wallet … Just like a regular credit card. Since the beginning of the year, airport officials across the country have confiscated about 500 credit card knives …. And say it’s becoming an increasing problem. Most of those were found in airports on the west coast, but Des Moines officials have found some here. TSA officials say in most cases, passengers simply forget they have them when they walk through the security check point. If a security officials finds one, you’ll be given the option to either take it out and mail it, check it or get rid of it. But, a reminder that they are considered weapons so having one in your possession at the checkpoint could result in a civil penalty. so always a good reminder to double check all your bags before you even leave for the airport!
