Nowadays, a lot of people travel by air, and everyone knows that you need two documents to board a plane — your passport and your boarding card. Although some people might have the electronic versions of those cards in their telephones, many still use the printed versions of them. If you are one of those people , this information will be useful.
Then, why shouldn’t you toss away your boarding card right after the flight? There is a simple reason why you should bring it home first, then get rid of it. It is a fact that every boarding card contains some confidential information that can easily be read through a QR code, which actually appears on all boarding cards.
Therefore, what should someone else do to get your confidential information (your name, address, phone number, e-mail address, etc.). It is necessary to scan the code through a mobile app. And that’s it, your personal information can be used in a very unpleasant way. Besides, these codes are readable from mobile screens, and that is why never post photos of your boarding cards on social media.
Be very careful, because it is currently really easy to obtain people’s confidential information and to use them in a fraudulent way.
