You may want to rethink tossing your airline boarding pass in the trash.
Security experts are warning people about personal information hidden in the barcodes. That, combined with the information that people put on social media, can create a lot of damage if hackers get ahold of it.
Airline barcodes contain more information than you think—including names, record locator and frequent flyer number and more. If a boarding pass gets into the hands of a clever thief, they can use that information to answer security questions on websites and hack into accounts.
Or, even worse, hackers can use that information, and combine it with other easily accessible personal information, to assume a person’s entire identity online.
Some advice: treat boarding passes like any other important document as a precaution.
