Boarding passes are handed out to passengers just before their departure.

Right before boarding, it’s like our lives depended on it.

But as we enter the cabin, the apparent use of boarding passes suddenly diminishes. They’re not needed to claim our luggage or any other purpose, although they may be needed when buying merchandise at the Duty Free shop at the arrival.

So with less importance, we slip our boarding passes at pockets on cabin seats, leave them at the hotel desk or simply throw them at the next available trash bin.

Such careless act could land us into trouble.

An unsuspecting piece of paper has a QR code embedded on it. When decoded, there can be so much personal information revealed from that QR code: your home address, banking info, email address, phone number.

Watch the video and share this to others, so next time everyone will avoid making the same mistake of discarding their boarding pass everywhere.
