What’s in a Boarding Pass Barcode? A Lot...The next time you’re thinking of throwing away a used boarding pass with a barcode on it, consider tossing the boarding pass into a document shredder instead. Two-dimensional barcodes and QR codes can hold a great deal of information, and the codes printed on airline boarding passes may allow someone to discover more about you, your future travel plans, and your frequent flyer account.

If the bar code reflects the data printed on the boarding pass, what is all the hoopla about? This story is only intended to create hysteria about nothing.
It really only affects people who post their boarding pass with what they think is sensitive plain text redacted. Not realizing it's encoded in the barcodes.
You beat me to the punch. I don't see anything that is 'encoded' that is not otherwise printed on the boarding pass.
Saw a picture of a naked lady in mine once.
Should I shred my iPhone then?
That information on these documents will not lead anyone to your private information anywhere. There are still other factors you need in order to steal someone's identity or hijack your frequent flyer account, unless you are careless enough to have a simple password for your account; in which case, the barcode info is the least of your problems. It is a good idea to destroy the boarding pass but not only because of the barcode.
